opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce

1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.
2 linker command line options are added:
1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

x86: Support Intel IBT with IBT property and IBT-enable PLT
To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
#define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002
#define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)
are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.
GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.
The followings changes are made to the Procedure Linkage Table (PLT):
1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

x86: Support Intel IBT with IBT property and IBT-enable PLT
To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
#define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002
#define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)
are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.
GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.
The followings changes are made to the Procedure Linkage Table (PLT):
1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.
2 linker command line options are added:
1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library. This patch defines them conditionally with PROVIDE, since a
shared library might need the local value. An example is glibc ld.so
local access to "_begin", "_etext" and "_end". (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)
We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable. An
example is freebsd libc dynamic access to "_end".

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

Add R_X86_64_[REX_]GOTPCRELX support to gas and ld
This patch adds support for the R_X86_64_GOTPCRELX and
R_X86_64_REX_GOTPCRELX relocations proposed in
https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0
to gas and ld. It updates gas to generate R_X86_64_GOTPCRELX,
R_X86_64_REX_GOTPCRELX if there is a REX prefix, relocation for memory
operand, foo@GOTPCREL(%rip). With the locally defined symbol, foo, we
convert
mov foo@GOTPCREL(%rip), %reg
to
lea foo(%rip), %reg
and convert
call/jmp *foo@GOTPCREL(%rip)
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg, foo@GOTPCREL(%rip)
to
test $foo, %reg
and convert
binop foo@GOTPCREL(%rip), %reg
to
binop $foo, %reg
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

x86-64: Add -z mark-plt and -z nomark-plt
The PLT entry in executables and shared libraries contains an indirect
branch, like
jmp *foo@GOTPCREL(%rip)
push $index_foo
jmp .PLT0
or
endbr64
jmp *foo@GOTPCREL(%rip)
NOP padding
which is used to branch to the function, foo, defined in another object.
Each R_X86_64_JUMP_SLOT relocation has a corresponding PLT entry.
The dynamic tags have been added to the x86-64 psABI to mark such PLT
entries:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/6d824a52a42d173eb838b879616c1be5870b593e
Add an x86-64 linker option, -z mark-plt, to mark PLT entries with
#define DT_X86_64_PLT (DT_LOPROC + 0)
#define DT_X86_64_PLTSZ (DT_LOPROC + 1)
#define DT_X86_64_PLTENT (DT_LOPROC + 3)
1. DT_X86_64_PLT: The address of the procedure linkage table.
2. DT_X86_64_PLTSZ: The total size, in bytes, of the procedure linkage
table.
3. DT_X86_64_PLTENT: The size, in bytes, of a procedure linkage table
entry.
and set the r_addend field of the R_X86_64_JUMP_SLOT relocation to the
memory offset of the indirect branch instruction. The dynamic linker
can use these tags to update the PLT section to direct branch.

ld: sframe: do not generate .sframe for PLT if no .sframe is in input BFDs
GNU ld creates SFrame stack trace info for the PLT. For x86 the linker-
created .sframe section is created in setup_gnu_properties. For s390 it
is created in create_dynamic_sections. For both, the section data is
itself emitted a bit later in late_size_sections. Note that for aarch64 the
linker does not create .sframe for PLT yet.
Recall that a previous patch 832ca9ef670 uncoupled
--no-ld-generated-unwind-info from the linker-generated .sframe
sections. This means that the linker now generates .sframe section (for
.plt*) for the first input BFD enthusiatically even when none of the
input BFDs have any .sframe section, unless --discard-sframe is also
added. The issue is that these (unexpected) linker-generated .sframe
sections (on x86_64, and s390) may now trip the linking process, e.g.,
when using --orphan-handling=error together with a linker script that
treats .sframe differently than the default linker script.
https://sourceware.org/pipermail/binutils/2026-January/147826.html
Further, with SFrame sections to be soon marked KEEP for fixing
GC/SFrame (PR ld/32769), the presence of these linker generated SFrame
sections will also cause emission of an empty .sframe (for x86_64 and
s390x), even when all input bfd's have no .sframe section.
This patch avoids creation of .sframe for .plt* if none of the input
BFDs had any .sframe section. This then avoids creation of empty
.sframe in linked objects on x86_64 and s390x, when none of the inputs
have SFrame sections. This also fixes PR ld/33830.
For the code changes:
Reviewed-by: Jens Remus <jremus@linux.ibm.com>
New testcases have (since the above Reviewed-by) been added. Since
--no-ld-generated-unwind-info is not supported on aarch64, add
target-specific ld tests. Additionally add a generic test (for all
targets that support SFrame) to ensure no output .sframe is generated if
users says no --gsframe or similar.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

x86: Support Intel IBT with IBT property and IBT-enable PLT
To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
#define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002
#define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)
are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.
GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.
The followings changes are made to the Procedure Linkage Table (PLT):
1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.
2 linker command line options are added:
1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

Add R_X86_64_[REX_]GOTPCRELX support to gas and ld
This patch adds support for the R_X86_64_GOTPCRELX and
R_X86_64_REX_GOTPCRELX relocations proposed in
https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0
to gas and ld. It updates gas to generate R_X86_64_GOTPCRELX,
R_X86_64_REX_GOTPCRELX if there is a REX prefix, relocation for memory
operand, foo@GOTPCREL(%rip). With the locally defined symbol, foo, we
convert
mov foo@GOTPCREL(%rip), %reg
to
lea foo(%rip), %reg
and convert
call/jmp *foo@GOTPCREL(%rip)
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg, foo@GOTPCREL(%rip)
to
test $foo, %reg
and convert
binop foo@GOTPCREL(%rip), %reg
to
binop $foo, %reg
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

x86-64: Improve PLT generation and synthetic PLT symbols
On x86-64, the procedure linkage table (PLT) is used to
1. Call external function.
2. Call internal IFUNC function. The best implementation is selected
for the target processor at run-time.
3. Act as the canonical function address.
4. Support LD_AUDIT to audit external function calls.
5. Support LD_PROFILE to profile external function calls.
PLT looks like:
PLT0: push GOT[1]
jmp *GOT[2]
nop
PLT1: jmp *GOT[name1_index]
push name1_reloc_index
jmp PLT0
GOT is an array of addresses. Initially the GOT entry of name1 is
filled with the address of the "push name1_reloc_index" instruction.
The function, name1, is called via "jmp *GOT[name1]" in the PLT entry.
Even when lazy binding is disabled by "-z now", the PLT0 entry may
still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for
canonical function address.
When linker is invoked with "-z bndplt", a different PLT layout in .plt
is used:
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
PLT1: push name1_reloc_index
bnd jmp PLT0
nop
together with a second PLT section, .pl.bnd:
PLT1: bnd jmp *GOT[name1_index]
nop
where the GOT entry of name1 is filled with the address of the push
instruction of the corresponding entry in .plt.
1. With lazy binding, when the external function, name1, is called the
first time, dynamic linker is called via PLT0 to update GOT[name1_index]
with the actual address of name1 and transfers control to name1
afterwards.
2. PLT is also used to call a local IFUNC function, name1, run-time
loader updates GOT[name1_index] when loading the module.
This patch
1. Remove PLT layout configurations from x86-64 backend_data.
2. Add generic, lay and non-lazy PLT layout configurations to x86-64
link_hash_table. Generic PLT layout includes the PLT entry templates,
information how to update the first instruction in PLT and PLT eh_frame
informaton, which are initialized in x86-64 setup_gnu_properties, based
on "-z bndplt" and target selection. PLT section alignment is also set
to PLT entry size for non-NaCl target.
3. Remove elf_x86_64_create_dynamic_sections. create_dynamic_sections
isn't always called, but GOT relocations need GOT relocations. Instead,
create all x86-64 specific dynamic sections with alignment to their entry
size in x86-64 setup_gnu_properties, which initializes elf.dynobj, so
that x86-64 check_relocs can be simplified.
4. Rewrite elf_x86_64_get_synthetic_symtab to check PLT sections against
all dynamic relocations to support both lazy and non-lazy PLTs.
There is no change in PLT. The only externally visible change is the
improvement of synthetic PLT symbols for .plt.got.

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

I've deliberately not fixed the "out of memory" errors since it's very

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.
Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages. For now I'm punting on this
one.
Changes to readelf output require lots of testsuite adjustment..

ELF: Add support for unique section ID to assembler
Clang's integrated assembler supports multiple section with the same
name:
.section .text,"ax",@progbits,unique,1
nop
.section .text,"ax",@progbits,unique,2
nop
"unique,N" assigns the number, N, as the section ID, to a section. The
valid values of the section ID are between 0 and 4294967295. It can be
used to distinguish different sections with the same section name.
This is useful with -fno-unique-section-names -ffunction-sections.
-ffunction-sections by default generates .text.foo, .text.bar, etc.
Using the same string can save lots of space in .strtab.
This patch adds section_id to bfd_section and reuses the linker
internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler
internal use to mark valid section_id. It also updates objdump to
compare section pointers if 2 sections comes from the same file since
2 different sections can have the same section name.

On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared

_GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on

On x86-64, for 32-bit PC-relative branches, we can generate PLT32

a marker for 32-bit PC-relative branches. Linker can always reduce
PLT32 relocation to PC32 if function is defined locally. Local

x86-64: Generate branch with PLT32 relocation
Since there is no need to prepare for PLT branch on x86-64, generate
R_X86_64_PLT32, instead of R_X86_64_PC32, if possible, which can be
used as a marker for 32-bit PC-relative branches.

From: "H.J. Lu" <hjl.tools@gmail.com>
Subject: [PATCH] x86: Treat R_X86_64_PLT32 as R_X86_64_PC32
On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared
objects must use PIC PLT. To use PIC PLT, you need to load
_GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on
x86-64 since x86-64 uses PC-relative PLT.
On x86-64, for 32-bit PC-relative branches, we can generate PLT32
relocation, instead of PC32 relocation, which can also be used as
a marker for 32-bit PC-relative branches. Linker can always reduce
PLT32 relocation to PC32 if function is defined locally. Local
functions should use PC32 relocation. As far as Linux kernel is
concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32
since Linux kernel doesn't use PLT.

x86: Update GNU_PROPERTY_X86_XXX macros
This patch updates GNU_PROPERTY_X86_XXX macros:
1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_AND_LO 0xc0000002
#define GNU_PROPERTY_X86_UINT32_AND_HI 0xc0007fff
2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000
#define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff
3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000
#define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff
4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.
GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined. The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

#define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000
#define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff
3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.

GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined. The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

x86: Update GNU_PROPERTY_X86_XXX macros
This patch updates GNU_PROPERTY_X86_XXX macros:
1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_AND_LO 0xc0000002
#define GNU_PROPERTY_X86_UINT32_AND_HI 0xc0007fff
2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000
#define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff
3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000
#define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff
4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.
GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined. The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Update GNU_PROPERTY_X86_XXX macros
This patch updates GNU_PROPERTY_X86_XXX macros:
1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_AND_LO 0xc0000002
#define GNU_PROPERTY_X86_UINT32_AND_HI 0xc0007fff
2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000
#define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff
3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000
#define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff
4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.
GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined. The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

x86: Update GNU_PROPERTY_X86_XXX macros
This patch updates GNU_PROPERTY_X86_XXX macros:
1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_AND_LO 0xc0000002
#define GNU_PROPERTY_X86_UINT32_AND_HI 0xc0007fff
2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000
#define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff
3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000
#define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff
4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.
GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined. The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

x86-64: Fix TLSDESC relaxation for x32
For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix
even if it isn't required. Otherwise linker can’t safely perform
GDesc -> IE/LE optimization. X32 TLSDESC sequences can be:
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
...

or the same sequence as LP64:
48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg
...

We need to support both sequences for x32. For both GDesc -> IE/LE
transitions,
67 ff 10 call *x@TLSCALL(%eax)

x86-64: Fix TLSDESC relaxation for x32
For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix
even if it isn't required. Otherwise linker can’t safely perform
GDesc -> IE/LE optimization. X32 TLSDESC sequences can be:
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
...
67 ff 10 call *x@TLSCALL(%eax)
or the same sequence as LP64:
48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg
...
ff 10 call *foo@TLSCALL(%rax)
We need to support both sequences for x32. For both GDesc -> IE/LE
transitions,
67 ff 10 call *x@TLSCALL(%eax)
should relaxed to
0f 1f 00 nopl (%rax)
For GDesc -> LE transition,
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
should relaxed to
40 c7 c0 fc ff ff ff rex movl $x@tpoff, %reg

x86-64: Fix TLSDESC relaxation for x32
For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix
even if it isn't required. Otherwise linker can’t safely perform
GDesc -> IE/LE optimization. X32 TLSDESC sequences can be:
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
...
67 ff 10 call *x@TLSCALL(%eax)
or the same sequence as LP64:
48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg
...
ff 10 call *foo@TLSCALL(%rax)
We need to support both sequences for x32. For both GDesc -> IE/LE
transitions,
67 ff 10 call *x@TLSCALL(%eax)
should relaxed to
0f 1f 00 nopl (%rax)
For GDesc -> LE transition,
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
should relaxed to
40 c7 c0 fc ff ff ff rex movl $x@tpoff, %reg

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support Intel IBT with IBT property and IBT-enable PLT
To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
#define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002
#define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)
are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.
GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.
The followings changes are made to the Procedure Linkage Table (PLT):
1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.
2 linker command line options are added:
1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

x86: Support Intel IBT with IBT property and IBT-enable PLT
To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
#define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002
#define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)
are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.
GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.
The followings changes are made to the Procedure Linkage Table (PLT):
1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.
2 linker command line options are added:
1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

[SFrame-V3] ld: add --discard-sframe command line option
Add a new command line option --discard-sframe to the linker.
This option allows users to prevent the linker from generating an output
.sframe section.
The rationale for this option is: Consider the case when say, the distro
is shipped with SFrame sections in the installed binaries/libraries. A
user application using these installed libraries, but not enabling
.sframe for itself just yet, will see an output .sframe corresponding to
the pulled in libraries. This is "partial" .sframe information for the
application. Adding such an option to the linker, gives user a way to
turn off the .sframe section completely without relying on a linker
script.
Previously, the existing --no-ld-generated-unwind-info option
controlled whether (not just .eh_frame for PLT entries, but also) SFrame
for PLT entries. The new command line option,
--discard-sframe now decouples SFrame from other unwind
formats (like .eh_frame), allowing for more control over the output
binary's SFrame data.
The option is added for architectures that currently support SFrame:
AArch64, s390x, and x86_64.

ld: sframe: do not generate .sframe for PLT if no .sframe is in input BFDs
GNU ld creates SFrame stack trace info for the PLT. For x86 the linker-
created .sframe section is created in setup_gnu_properties. For s390 it
is created in create_dynamic_sections. For both, the section data is
itself emitted a bit later in late_size_sections. Note that for aarch64 the
linker does not create .sframe for PLT yet.
Recall that a previous patch 832ca9ef670 uncoupled
--no-ld-generated-unwind-info from the linker-generated .sframe
sections. This means that the linker now generates .sframe section (for
.plt*) for the first input BFD enthusiatically even when none of the
input BFDs have any .sframe section, unless --discard-sframe is also
added. The issue is that these (unexpected) linker-generated .sframe
sections (on x86_64, and s390) may now trip the linking process, e.g.,
when using --orphan-handling=error together with a linker script that
treats .sframe differently than the default linker script.
https://sourceware.org/pipermail/binutils/2026-January/147826.html
Further, with SFrame sections to be soon marked KEEP for fixing
GC/SFrame (PR ld/32769), the presence of these linker generated SFrame
sections will also cause emission of an empty .sframe (for x86_64 and
s390x), even when all input bfd's have no .sframe section.
This patch avoids creation of .sframe for .plt* if none of the input
BFDs had any .sframe section. This then avoids creation of empty
.sframe in linked objects on x86_64 and s390x, when none of the inputs
have SFrame sections. This also fixes PR ld/33830.
For the code changes:
Reviewed-by: Jens Remus <jremus@linux.ibm.com>
New testcases have (since the above Reviewed-by) been added. Since
--no-ld-generated-unwind-info is not supported on aarch64, add
target-specific ld tests. Additionally add a generic test (for all
targets that support SFrame) to ensure no output .sframe is generated if
users says no --gsframe or similar.

x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

x86: Ignore CS/DS/ES/SS segment-override prefixes in 64-bit mode
"In 64-bit mode, the CS, DS, ES, and SS segment-override prefixes have
no effect. These four prefixes are not treated as segment-override
prefixes for the purposes of multiple-prefix rules. Instead, they are
treated as null prefixes." (AMD APM v2).
However, objdump disassembles instructions containing those ignored
prefixes by still generating that segment override:
66 66 2e 0f 1f 84 00 data16 nopw %cs:0x0(%rax,%rax,1)
00 00 00 00
Print those segment override prefixes as excessive ones:
66 66 2e 0f 1f 84 00 data16 cs nopw 0x0(%rax,%rax,1)
00 00 00 00
which is what they actually are - they have no effect and the decoding
hardware ignores them.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert

Support x86-64 TLS code sequences without PLT
We can generate x86-64 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *__tls_get_addr@GOTPCREL(%rip)
instead of direct call:
call __tls_get_addr[@PLT]
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, one 0x66 prefix before call instruction is
removed to make room for indirect call. For local dynamic model, we
simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and
generate a 5-byte nop, instead of 4-byte, before mov instruction in
32-bit. Since linker may convert
call *__tls_get_addr@GOTPCREL(%rip)
to
addr32 call __tls_get_addr
when producing static executable, both patterns are recognized.

(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
What this code does is add whitespace after the instruction mnemonic
and before the instruction operands.
The problem I ran into when working on this code can be seen by
assembling this input file:
.text
nop
retq
Now, when I disassemble, here's the output. I've replaced trailing
whitespace with '_' so that the issue is clearer:
Disassembly of section .text:
0000000000000000 <.text>:
0: 90 nop
1: c3 retq___
Notice that there's no trailing whitespace after 'nop', but there are
three spaces after 'retq'!
What happens is that instruction mnemonics are emitted into a buffer
instr_info::obuf, then instr_info::mnemonicendp is setup to point to
the '\0' character at the end of the mnemonic.
When we emit the whitespace, this is then added starting at the
mnemonicendp position. Lets consider 'retq', first the buffer is
setup like this:
'r' 'e' 't' 'q' '\0'
Then we add whitespace characters at the '\0', converting the buffer
to this:
'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
initially, the buffer is setup like this:
'x' 'c' 'h' 'g' '\0'
Then in NOP_Fixup we spot that we have an instruction that is an alias
for 'nop', and adjust the buffer to this:
'n' 'o' 'p' '\0' '\0'
The second '\0' is left over from the original buffer contents.
However, when we rewrite the buffer, we don't afjust mnemonicendp,
which still points at the second '\0' character.
Now, when we insert whitespace we get:
'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
Notice the whitespace is inserted after the first '\0', so, when we
print the buffer, the whitespace is not printed.
The fix for this is pretty easy, I can change NOP_Fixup to adjust
mnemonicendp, but now a bunch of tests start failing, we now produce
whitespace after the 'nop', which the tests don't expect.
So, I could update the tests to expect the whitespace....
...except I'm not a fan of trailing whitespace, so I'd really rather
not.
Turns out, I can pretty easily update the whitespace emitting code to
spot instructions that have zero operands and just not emit any
whitespace in this case. So this is what I've done.
I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
probably a good thing, though this is not really required any more.
I've then updated all the tests that I saw failing to adjust the
expected patterns to account for the change in whitespace.

opcodes/i386: remove trailing whitespace from insns with zero operands
While working on another patch[1] I had need to touch this code in
i386-dis.c:
ins->obufp = ins->mnemonicendp;
for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
oappend (ins, " ");
oappend (ins, " ");
(*ins->info->fprintf_styled_func)
(ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
