From 6d6c25c8eaaf42755a759beeb2996502322b960c Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 18 Nov 2019 17:09:01 +1030 Subject: [PATCH] elf_backend_modify_headers This patch renames elf_backend_modify_program_headers and moves the elf.c code tweaking the ELF file header for -pie -Ttext-segment to a new function, _bfd_elf_modify_headers, which then becomes the default elf_backed_modify_headers and is called from any other target elf_backed_modify_headers. * elf-bfd.h (struct elf_backend_data ): Rename from elf_backend_modify_program_headers. (_bfd_elf_modify_headers): Declare. * elf.c (assign_file_positions_except_relocs): Set elf_program_header_size. Always call elf_backend_modify_headers. Extract code modifying file header.. (_bfd_elf_modify_headers): ..to here. New function. * elf32-arm.c (elf_backend_modify_headers): Renamed from elf_backend_modify_program_headers. * elf32-i386.c: Similarly. * elf64-x86-64.c: Similarly. * elfxx-target.h: Similarly. Default elf_backend_modify_headers to _bfd_elf_modify_headers. * elf-nacl.h (nacl_modify_headers): Rename from nacl_modify_program_headers. * elf-nacl.c (nacl_modify_headers): Rename from nacl_modify_program_headers and call _bfd_elf_modify_headers. * elf32-rx.c (elf32_rx_modify_headers): Similarly. * elf32-spu.c (spu_elf_modify_headers): Similarly. * elfnn-ia64.c (elfNN_ia64_modify_headers): Similarly. * elf32-sh.c (elf_backend_modify_program_headers): Don't undef. --- bfd/ChangeLog | 24 +++++++ bfd/elf-bfd.h | 4 +- bfd/elf-nacl.c | 123 +++++++++++++++++------------------ bfd/elf-nacl.h | 2 +- bfd/elf.c | 76 ++++++++++++---------- bfd/elf32-arm.c | 6 +- bfd/elf32-i386.c | 6 +- bfd/elf32-rx.c | 7 +- bfd/elf32-sh.c | 2 - bfd/elf32-spu.c | 155 +++++++++++++++++++++++---------------------- bfd/elf64-x86-64.c | 6 +- bfd/elfnn-ia64.c | 9 ++- bfd/elfxx-target.h | 6 +- 13 files changed, 230 insertions(+), 196 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 2184208038..a6705ef688 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,27 @@ +2019-11-18 Alan Modra + + * elf-bfd.h (struct elf_backend_data ): + Rename from elf_backend_modify_program_headers. + (_bfd_elf_modify_headers): Declare. + * elf.c (assign_file_positions_except_relocs): Set + elf_program_header_size.
