From c74f7d1c6c5a968330208757f476c67a4bb66643 Mon Sep 17 00:00:00 2001 From: Jon Turney Date: Tue, 7 Apr 2015 20:49:08 +0100 Subject: Allow gdb to find debug symbols file by build-id for PE file format also This promotes BFD's struct elf_build_id to the generic struct bfd_build_id, populated when an ELF or PE BFD is read. gdb is updated to use that, and to use the build-id to find symbols for PE files also. There is currently no generic way to extract the build-id from an object file, perhaps an option to objdump to do this might make sense? On x86_64-pc-cygwin, gdb's sepdebug.exp changes: -# of unsupported tests 1 +# of expected passes 90 I don't seem to get consistent testsuite runs on i686-linux-gnu, but there don't appear to be any regressions. bfd/ChangeLog: 2015-06-10 Jon Turney * elf-bfd.h : Remove struct elf_build_id. * bfd.c : Add struct bfd_build_id. * bfd-in2.h: Regenerate. * elf.c (elfobj_grok_gnu_build_id): Update to use bfd_build_id. * libpei.h: Add protoype and macros for bfd_XXi_slurp_codeview_record. * peXXigen.c (_bfd_XXi_slurp_codeview_record): Make public * peicode.h (pe_bfd_read_buildid): Add. (pe_bfd_object_p): Use pe_bfd_read_buildid(). gdb/ChangeLog: 2015-06-10 Jon Turney * build-id.c: Don't include elf-bfd.h. (build_id_bfd_get): Use bfd_build_id. (build_id_verify): Ditto. * build-id.h: Ditto. (find_separate_debug_file_by_buildid): Ditto. * python/py-objfile.c: Don't include elf-bfd.h. (objfpy_get_build_id) Use bfd_build_id. (objfpy_build_id_matches, objfpy_lookup_objfile_by_build_id): Ditto. * coffread.c: Include build-id.h. (coff_symfile_read): Try find_separate_debug_file_by_buildid. gdb/doc/ChangeLog: 2015-06-10 Jon Turney * gdb.texinfo (Separate Debug Files): Document that PE is also supported. gdb/testsuite/ChangeLog: 2015-06-10 Jon Turney * gdb.base/sepdebug.exp: Add EXEEXT where needed. * lib/gdb.exp (get_build_id): Teach how to extract build-id from a PE file. * lib/future.exp (gdb_find_objdump): Add gdb_find_objdump.
