--- Comment #16 from Sourceware Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <h...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=f752be8f916efa70aea9c2e4f664c75690fd136c commit f752be8f916efa70aea9c2e4f664c75690fd136c Author: H.J. Lu <hjl.to...@gmail.com> Date: Tue Jul 22 14:09:48 2025 -0700 strip: Properly handle LLVM IR bitcode commit 717a38e9a02109fcbcb18bb2ec3aa251e2ad0a0d Author: H.J. Lu <hjl.to...@gmail.com> Date: Sun May 4 05:12:46 2025 +0800 strip: Add GCC LTO IR support added "-R .gnu.lto_.*" to strip to remove all GCC LTO sections. When "-R .gnu.lto_.*" is used, the plugin target is ignored so that all LTO sections are stripped as the regular sections. It works for the slim GCC LTO IR since the GCC LTO IR is stored in the regular sections. When the plugin target is ignored, the GCC LTO IR can be recognized as the normal object files. But it doesn't work for the slim LLVM IR which is stored in a standalone file. 1. Add bfd_check_format_matches_lto and bfd_check_format_lto to take an argument, lto_sections_removed, to indicate if all LTO sections should be removed. 2. Update strip to always enable the plugin target so that the plugin target is enabled when checking for bfd_archive. 3. Update strip to ignore the plugin target for bfd_object when all LTO sections should be removed. If the object is unknown, copy it as an unknown file without any messages. 4. Treat the "-R .llvm.lto" strip option as removing all LTO sections. bfd/ PR binutils/33198 * format.c (bfd_check_format_lto): New function. (bfd_check_format): Call bfd_check_format_matches_lto. (bfd_check_format_matches): Renamed to ... (bfd_check_format_matches_lto): This. Add an argument, lto_sections_removed, to indicate if all LTO sections should be removed and don't match the plugin target if lto_sections_removed is true. (bfd_check_format_matches): Call bfd_check_format_matches_lto. * bfd-in2.h: Regenerated. binutils/ PR binutils/33198 * objcopy.c (copy_archive): Call bfd_check_format_lto, instead of bfd_check_format, and pass lto_sections_removed. Remove the non-fatal message on unknown element since it will be copied as an unknown file. (copy_file): Don't check lto_sections_removed when enabling LTO plugin in strip. (copy_file): Ignore the plugin target first if all LTO sections should be removed. Try with the plugin target next if ignoring the plugin target failed to match the format. (strip_main): Also set lto_sections_removed for -R .llvm.lto. * testsuite/binutils-all/x86-64/pr33198.c: New file. * testsuite/binutils-all/x86-64/x86-64.exp (run_pr33198_test): New. Run binutils/33198 tests. * testsuite/lib/binutils-common.exp (llvm_plug_opt): New. (CLANG_FOR_TARGET): New. Set to "clang" for native build if "clang -v" reports "clang version". Signed-off-by: H.J.
