2015-06-15Allow gdb to find debug symbols file by build-id for PE file format alsoJon Turney8-21/+137
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 <jon.turney@dronecode.org.uk> * 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.

2015-06-05ppc476 linker workaround shared lib fixesAlan Modra2-0/+58
When building a shared lib from non-PIC objects, we'll get dynamic text relocations. These need to move with any insns we move. Otherwise the dynamic reloc will modify the branch, resulting in crashes and other unpleasant behaviour. Also, ld -r --ppc476-workaround used with sufficiently aligned PIC objects needs a fix for emitted REL16 relocs. bfd/ * elf64-ppc.c (ppc_elf_relocate_section): Move dynamic text relocs with insns moved by --ppc476-workaround. Correct output of REL16 relocs. ld/testsuite/ * ld-powerpc/ppc476-shared.s, * ld-powerpc/ppc476-shared.lnk, * ld-powerpc/ppc476-shared.d, * ld-powerpc/ppc476-shared2.d: New tests. * ld-powerpc/powerpc.exp: Run them.
