2017-09-10PowerPC64 --plt-alignAlan Modra2-3/+21
This changes the PowerPC64 --plt-align option to perform the usual alignment of code as suggested by its name, as well as the previous behaviour of padding so as to reduce boundary crossing. The old behaviour is had by using a negative parameter. The default is also changed to align plt stub code by default to 32 byte boundaries, the point being to get better bctr branch prediction on power8 and power9 hardware. bfd/ * elf64-ppp.c (plt_stub_pad): Handle positive and negative plt_stub_align. ld/ * ld.texinfo (--plt-align): Describe new behaviour of option. * emultempl/ppc64elf.em (params): Default plt_stub_align to 5. * testsuite/ld-powerpc/powerpc.exp: Pass --no-plt-align for selected tests. * testsuite/ld-powerpc/relbrlt.d: Pass --no-plt-align. * testsuite/ld-powerpc/elfv2so.d: Adjust expected output.

2017-09-09x86: Properly handle __ehdr_startH.J. Lu5-23/+77
After _bfd_i386_elf_convert_load and _bfd_x86_64_elf_convert_load are removed, elf_i386_convert_load_reloc and elf_x86_64_convert_load_reloc see __ehdr_start as an undefined symbol when they are called from check_relocs to convert GOT relocations against local symbols. But __ehdr_start will be defined as a hidden symbol by linker at the later stage if it is referenced. This patch marks __ehdr_start as a defined local symbol at the start of check_relocs if it is referenced and not defined. bfd/ PR ld/22115 * elf32-i386.c (elf_i386_convert_load_reloc): Check linker_def.

2017-09-07RISC-V: Support PCREL_* relocations agaist weak undefined symbolsPalmer Dabbelt2-5/+76
I recently modified our Linux port's base address such the absolute address 0 is no longer addressable as a 32-bit PC-relative offset. Since Linux links a weak undefined symbol in an intermediate binary, it needs to be able to reference absolute address 0. This patch changes R_RISCV_PCREL_* relocations to absolute relocations while resolving them in order to allow these symbols to be referenced in PC-relative programs linked at high addresses. Note that this doesn't apply to PIC, which also uses PC-relative relocations, just to position-dependent objects, which we use to allow programs to be linked at high addresses. In case some of our embedded users are using R_RISCV_PCREL_* as a hacked up method of getting position-independent binaries (which can work if you have very simple programs), we only convert the relocations when the PC-relative version would overflow. bfd/ChangeLog: 2017-09-07 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv.c (riscv_zero_pcrel_hi_reloc): New function.

Instead of converting GOT relocations when sizing dynamic sections, we convert GOT relocations during relocation check.

elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are very similar, except for the followings: 1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH. elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE for both i386 and x86-64. 2, x86-64 sets tlsdesc_plt, but i386 doesn't.
