Rainer Orth [PR build/29791] gnulib: Disable _GL_ATTRIBUTE_DEALLOC on Solaris 3y ago

0001-use-windows-stat

Do not adjust mtime timezone on Windows PR win32/25302 notes that gdb will crash when trying to "run" even a simple program on Windows. The essential bug here is that the BFD cache can easily be corrupted -- I have sent a separate patch for that. The particular reason that the cache is corrupted on Windows is that gnulib overrides "stat" to make it do timezone adjustment -- but BFD does not use this version of stat. The difference here triggers the latent cache bug, but can also cause other bugs as well; in particular it can cause spurious warnings about source files being newer. This patch simply removes the stat override on mingw, making gnulib and BFD agree. I tested this by backing out the local AdaCore changes to work around this bug and then verifying that I could reproduce it. Then, I applied this patch and verified that "run" works again. 2020-09-08 Tom Tromey <tromey@adacore.com> PR win32/25302: * update-gnulib.sh: Apply stat patch. * patches/0001-use-windows-stat: New file. * import/m4/stat.m4: Update. * configure: Rebuild.

0002-no-solaris-_gl_attribute_dealloc

[PR build/29791] gnulib: Disable _GL_ATTRIBUTE_DEALLOC on Solaris gdbsupport compilation badly fails with GCC 12 on Solaris, with errors like ../gnulib/config.h:1693:72: error: ‘malloc’ attribute argument 1 is ambiguous 1693 | # define _GL_ATTRIBUTE_DEALLOC(f, i) __attribute__ ((__malloc__ (f, i))) | ^ ../gnulib/config.h:1693:72: note: use a cast to the expected type to disambiguate We've not yet been able to determine where the ambiguity actually lies, so this patch works around the issue by disabling _GL_ATTRIBUTE_DEALLOC on Solaris, at least as a workaround for GDB 13. As Tom suggested in the PR, this is done using our infrastructure for local gnulib patches. Tested on sparcv9-sun-solaris2.11, amd64-pc-solaris2.11, and x86_64-pc-linux-gnu.
