--- Comment #2 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alan Modra <amo...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=e76790600aeba4939225eda32e59642ed2813ac8 commit e76790600aeba4939225eda32e59642ed2813ac8 Author: Alan Modra <amo...@gmail.com> Date: Tue Nov 26 22:32:51 2019 +1030 PR23652, Use symbols from debug bfd for _bfd_elf_find_function Sometimes DWARF info for a function is incomplete, and the function can be retrieved by examining symbols. However, when separate debug files are used it may be that the original file is completely stripped of symbols. This patch teaches BFD to look at symbols from the debug file in that case. The patch also removes arm_elf_find_function, instead implementing elf_backend_maybe_function_sym. arm_elf_find_function was written before the generic _bfd_elf_find_function called maybe_function_sym. aarch64 copied arm, so that file gets the same treatment. There is some chance this will speed up arm and aarch64 lookup of function/line. PR 23652 * dwarf2.c (_bfd_dwarf2_stash_syms): New function. (_bfd_dwarf2_find_nearest_line): Use it here, passing syms to _bfd_elf_find_function. Call _bfd_elf_find_function in cases where _bfd_elf_find_nearest_line would do so. * elf.c (_bfd_elf_find_nearest_line): Omit _bfd_elf_find_function for dwarf2. * elfxx-mips.c (_bfd_mips_elf_find_nearest_line): Similarly. Tidy. * elf32-arm.c (elf32_arm_maybe_function_sym): New function. (elf_backend_maybe_function_sym): Define. (arm_elf_find_function, elf32_arm_find_nearest_line): Delete. (bfd_elf32_find_nearest_line): Don't define. * elfnn-aarch64.c (elfNN_aarch64_maybe_function_sym): New function. (elf_backend_maybe_function_sym): Define. (aarch64_elf_find_function, elfNN_aarch64_find_nearest_line): Delete. (bfd_elfNN_find_nearest_line): Don't define. -- You are receiving this mail because: You are on the CC list for the bug.
