From 7f3bf38453acbabf7286dd7f8ce2688282e7b9cd Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 27 Nov 2019 18:00:59 +1030 Subject: PR23652, Use symbols from debug bfd for _bfd_elf_find_function properly There were a number of problems with the previous patch. Firstly, _bfd_dwarf2_stash_syms didn't do anything when the original file had dynamic symbols, and secondly, info found by the symbol search didn't make it out of _bfd_elf_find_nearest_line except in the case of DWARF functions without external linkage. PR 23652 * dwarf2.c (_bfd_dwarf2_stash_syms): Break out of loop on finding matching section. (_bfd_dwarf2_find_nearest_line): Return an int, with value 2 when returning info from the symbol table. Do the _bfd_elf_find_function search also when !found. Call _bfd_dwarf2_stash_syms regardless of symbols. * elf64-alpha.c (elf64_alpha_find_nearest_line): Accept dwarf2 result of 1 only. * elfxx-mips.c (_bfd_mips_elf_find_nearest_line): Likewise. * libbfd-in.h (_bfd_dwarf2_find_nearest_line): Update prototype. * libbfd.h: Regenerate. --- bfd/ChangeLog | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'bfd/ChangeLog') diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 4a0852e..ab9174d 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,6 +1,21 @@ 2019-11-27 Alan Modra PR 23652 + * dwarf2.c (_bfd_dwarf2_stash_syms): Break out of loop on finding + matching section. + (_bfd_dwarf2_find_nearest_line): Return an int, with value 2 when + returning info from the symbol table.
