2016-05-13ld -z combreloc reloc sortingAlan Modra2-2/+6
PLT relocs don't appear in .rela.dyn, at least not when using normal linker scripts. However, if they do, then they ought to be placed last rather than in the middle of other relocs. * elf-bfd.h (elf_reloc_type_class): Put reloc_class_plt last.

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.
