[SFrame-V3] libsframe: testsuite: add new testcases for SFRAME_FDE_TYPE_FLEX This patch adds two new tests for SFrame V3 changes, focusing on the newly added flexible FDE TYPE SFRAME_FDE_TYPE_FLEX. Following tests are added: - be-flipping-v3.c: Validates that big-endian SFrame V3 data is correctly endian flipped when run on little-endian hosts. It verifies the decoding of CFA offsets and the new V3 register/offset metadata bitfields using the SFRAME_V3_FLEX_FDE_OFFSET_REG_* macros. - findfre-flex-1.c: Tests a variety of sframe_find_fre lookup scenarios, apart from checking the basic encoder/decoder APIs. Documentation for the binary test data DATA-BE-V3 is provided in README-be-flipping-v3 to ensure reproducibility. libsframe/ * Makefile.in: Regenerate. * testsuite/libsframe.decode/DATA-BE-V3: New test data. * testsuite/libsframe.decode/README-be-flipping-v3: New file. * testsuite/libsframe.decode/be-flipping-v3.c: New test. * testsuite/libsframe.decode/decode.exp: Run be-flipping-v3. * testsuite/libsframe.decode/local.mk: Add be-flipping-v3. * testsuite/libsframe.find/find.exp: Run findfre-flex-1. * testsuite/libsframe.find/findfre-flex-1.c: New test. * testsuite/libsframe.find/local.mk: Add findfre-flex-1.

libsframe: add the SFrame library libsframe is a library that allows you to: - decode a .sframe section - probe and inspect a .sframe section - encode (and eventually write) a .sframe section. This library is currently being used by the linker, readelf, objdump. This library will also be used by the SFrame unwinder which is still to be upstream'd. The file include/sframe-api.h defines the user-facing APIs for decoding, encoding and probing .sframe sections. A set of error codes together with their error message strings are also defined. Endian flipping is performed automatically at read and write time, if cross-endianness is detected. ChangeLog: * Makefile.def: Add libsframe as new module with its dependencies. * Makefile.in: Regenerated. * binutils/Makefile.am: Add libsframe. * binutils/Makefile.in: Regenerated. * configure: Regenerated * configure.ac: Add libsframe to host_libs. * libsframe/Makefile.am: New file. * libsframe/Makefile.in: New file. * libsframe/aclocal.m4: New file. * libsframe/config.h.in: New file. * libsframe/configure: New file. * libsframe/configure.ac: New file. * libsframe/sframe-error.c: New file. * libsframe/sframe-impl.h: New file. * libsframe/sframe.c: New file. include/ChangeLog: * sframe-api.h: New file. testsuite/ChangeLog: * libsframe/testsuite/Makefile.am: New file. * libsframe/testsuite/Makefile.in: Regenerated. * libsframe/testsuite/libsframe.decode/Makefile.am: New file. * libsframe/testsuite/libsframe.decode/Makefile.in: Regenerated. * libsframe/testsuite/libsframe.decode/decode.exp: New file. * libsframe/testsuite/libsframe.encode/Makefile.am: Likewise. * libsframe/testsuite/libsframe.encode/Makefile.in: Regenerated. * libsframe/testsuite/libsframe.encode/encode.exp: New file. * libsframe/testsuite/libsframe.encode/encode-1.c: Likewise. * libsframe/testsuite/libsframe.decode/be-flipping.c: Likewise. * libsframe/testsuite/libsframe.decode/frecnt-1.c: Likewise. * libsframe/testsuite/libsframe.decode/frecnt-2.c: Likewise. * libsframe/testsuite/libsframe.decode/DATA-BE: New file. * libsframe/testsuite/libsframe.decode/DATA1: Likewise. * libsframe/testsuite/libsframe.decode/DATA2: Likewise.

tidy m4 plugin config support In CLANG_PLUGIN_FILE it is possible for plugin_file to be non-NULL when LLVMgold.so does not exist. configure output is messy, with results not printed against their "checking.." line, eg. checking for clang... (cached) yes checking for clang plugin file... checking for x86_64-pc-linux-gnu-ar... (cached) ar --plugin /usr/lib/llvm-20/lib/clang/20/../../LLVMgold.so /usr/lib/llvm-20/lib/clang/20/../../LLVMgold.so This patch fixes those problems, and a similar interposition of other configure output between AC_MSG_CHECKING and AC_MSG_RESULT in gcc-plugin.m4. It also tidies some of the message text, and makes similar code in gcc-plugin.m4 and clang-plugin.m4 a little more consistent. config/ * clang-plugin.m4 (CLANG_PLUGIN_FILE): Don't place checks for tools (llvm-config, ar) inside AC_MSG_CHECKING..AC_MSG_RESULT for clang plugin file.

[SFrame-V3] bfd: ld: sframe: avoid unnecessary decoding of SFrame FREs at link time At link time, in _bfd_elf_merge_section_sframe (), it suffices to bring over the all per-function stack trace metadata (all FREs) as a blob into the SFrame encoder object. There is no need to "decode" each SFrame FRE, only to add them in a serial fashion. This is an optimization, and not directly related to any SFrame V3 related changes to the specification. This should also bring us a step closer to supporting SFrame for targets which use linker relaxations. Removing the need to decode the input FREs can allow the linker to simply use the available set of FREs from (relocated) contents. To support targets using linker relaxations in SFrame, other changes in the SFrame parse functionality time may also be necessary, but this brings us just a step closer. Add two new APIs to accomplish this: - sframe_decoder_get_fres_buf, and - sframe_encoder_add_fres_buf bfd/ * elf-sframe.c (_bfd_elf_merge_section_sframe): Get all FRE data and add it all in bulk. libsframe/ * libsframe.ver: Add new APIs. * sframe.c (sframe_buf_fre_entry_size): New internal API to get size of one SFrame FRE at the indicated buffer location, without fully "decoding" the SFrame FRE.

[SFrame-V3] libsframe: bump so version to libsframe.so.3.0.0 Consolidate the 2.0 and 2.1 nodes into a new 3.0 node. In subsequent patches for releasing SFrame V3, libsframe APIs will be affected. A non-exhaustive list of noteworthy changes are mentioned next. Some existing APIs (breaking binary compatibility) by adding an additional arg to these: - sframe_fre_get_ra_offset - sframe_fre_get_fp_offset - sframe_fre_get_cfa_offset Change of argument type: - sframe_find_fre The behaviour of some APIs will change: - sframe_encoder_write now writes out V3. And lastly removal of two APIs: - sframe_decoder_get_funcdesc - sframe_encoder_add_funcdesc Above make this release of the library binary incompatible with previous release, hence a version bump and new version node 3.0. Reviewed-by: Jens Remus <jremus@linux.ibm.com> libsframe/ * libsframe.ver: Create a new 3.0 node. Remove the 2.0 node. * libtool-version: Bump the so version.

include: libsframe: rename SFrame V3 Flexible FDE macros to CTRLWORD The existing SFrame V3 macros for Flexible FDEs used the term 'OFFSET' to refer to the data word encoding control/register data word. This can be confusing, as the control data word (register ID, dereference flags) is distinct from a stack offset. This patch renames these macros to use 'CTRLWORD' to better reflect their purpose. It also updates the assembler and libsframe dumper to use the new nomenclature. No functional change.

README

libsframe is a support library for the GNU Binutils collection (currently used
by GNU ld, objdump, etc.) to read and write SFrame section data.

Note: This library is currently intended for internal use by GNU Binutils only.
Strict guarantees for ABI compatibility are not provided, and external projects
should not rely on the stability of these interfaces.
