2016-05-03Add a do_assignments hook to ldemulH.J. Lu2-0/+130
When ELF relocation check is moved after lang_gc_sections, we should call bfd_elf_record_link_assignment before ELF relocation check so that linker defined symbols will be processed earlier to stabilize symbols.

2016-05-03[AArch64] Also puts value in place for R_AARCH64_RELATIVEJiong Wang4-5/+20
When handling absolute relocations for global symbols bind within the shared object, AArch64 will generate one dynamic RELATIVE relocation, but won't apply the value for this absolution relocations at static linking stage. This is different from AArch64 gold linker and x86-64. This is not a bug as AArch64 is RELA, there is only guarantee that relocation addend is placed in the relocation entry. But some system softwares originally writen for x86-64 might assume AArch64 bfd linker gets the same behavior as x86-64, then they could take advantage of this buy skipping those RELATIVE dynamic relocations if the load address is the same as the static linking address. This patch makes AArch64 BFD linker applies absolution relocations at static linking stage for scenario described above. Meanwhile old AArch64 android loader has a bug (PR19163) which relies on current linker behavior as a workaround, so the same option --no-apply-dynamic-relocs added.

2016-04-26add casts to avoid arithmetic on void *Trevor Saunders3-5/+11
arithmetic on void * is undefined in ISO C, so we should avoid it. In GNU C sizeof void * is defined as 1, and that is pretty clearly what this code wants, so change it to do arithmetic on bfd_byte *. Unfortunately most of the argument types come from virtual function interfaces so changing the types to bfd_byte * isn't trivial though it might make the code clearer. So for the moment its easiest to leave the variable types as void * and cast before doing arithmetic. bfd/ChangeLog: 2016-04-26 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * elf32-rx.c (rx_set_section_contents): Avoid arithmetic on void *. * mmo.c (mmo_get_section_contents): Likewise.

When check_relocs is called after gc-sections has run, _bfd_elf_link_create_dynstrtab may be called with an dynamic object and hash_table->dynobj may be NULL. We may not set dynobj, an input file holding linker created dynamic sections to the dynamic object, which has its own dynamic sections. We need to find a normal input file to hold linker created sections if possible. Otherwise ld will crash during LTO input rescan when linker created dynamic section overrides input dynamic section. * elflink.c (_bfd_elf_link_create_dynstrtab): Set dynobj to a normal input file if possible.

2016-04-14bfd/arc: Rename enum entries to avoid conflictsAndrew Burgess2-17/+25
In bfd/elf32-arc.c an enum is created that contains entries with generic names like 'NONE' and 'OFF'. This has been fine for now, but I had a need to include opcode/arc.h into bfd/elf32-arc.c. Unfortunately opcode/arc.h includes a different enum with identical generic names. Given that changing the enum in the header file could mean wide-ranging changes, while changing the enum in the .c file is limited to only changing the one file, I've added a prefix to the enum in the .c file. This commit does not add the new include, that will come later. There should be no functional change with this commit. bfd/ChangeLog: * elf32-arc.c (tls_got_entries): Add 'TLS_GOT_' prefix to all entries. (elf_arc_relocate_section): Update enum uses. (elf_arc_check_relocs): Likewise. (elf_arc_finish_dynamic_symbol): Likewise.
