2017-09-19PowerPC64 stubs don't match calculated sizeAlan Modra2-6/+7
After the PR 21411 fix, the linker generated .eh_frame for ppc64 glink can be edited by the generic code. The sequence of events goes something like: 1) Some object file adds .eh_frame aligned to 8, making the output .eh_frame aligned to at least 8, so linker generated .eh_frame FDE is padded to an 8 byte boundary. 2) All .eh_frame past the glink .eh_frame is garbage collected. 3) Generic code detects that last FDE (the glink .eh_frame) doesn't need to be padded to an 8 byte boundary, reducing size from 88 to 84. 4) elf64-ppc.c check fails. PR 21441 * elf64-ppc.c (ppc64_elf_build_stubs): Don't check glink_eh_frame size.
2017-09-19PR22150, ld keeps a version reference for gc'd symbolsAlan Modra2-117/+118
elf_gc_sweep_symbol should run after verdefs are calculated, since the verdef code creates symbols for the versions. However, elf_gc_sweep_symbol needs to run before verrefs so as to not emit useless verrefs for symbols that are gc'd. I've also removed a _bfd_elf_link_renumber_dynsyms calls added by Maciej after I fussed about it when reviewing. On further examination the call appears to be unnecessary. Looking at renumber_dynsyms also made me realize that the test to exclude .gnu.version has been wrong since 2016-04-26 (git commit d5486c4372), so fix that too. PR 22150 * elflink.c (bfd_elf_size_dynamic_sections): Garbage collect symbols before calculating verrefs. Don't renumber dynsyms after gc. Exclude .gnu.version when zero or one dynsym.

2017-09-15Error when 32-bit ar tries to handle 4G or larger filesAlan Modra2-0/+12
We used to silently truncate the size returned by stat() to 32 bits. While it is possible to make binutils handle a 64-bit off_t on a 32-bit host, to me the effort needed doesn't seem worth the benefit. Instead, error if we truncate the size.

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.

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.

Lu <hjl.tools@gmail.com> Date: Fri Oct 21 15:13:37 2011 +0000 Put IRELATIVE relocations after JUMP_SLOT. bfd/ 2011-10-21 H.J. Lu <hongjiu.lu@intel.com> PR ld/13302 * elf32-i386.c (elf_i386_link_hash_table): Add next_jump_slot_index and next_irelative_index. (elf_i386_link_hash_table_create): Initialize next_jump_slot_index and next_irelative_index. (elf_i386_allocate_dynrelocs): Increment reloc_count instead of next_tls_desc_index. (elf_i386_size_dynamic_sections): Set next_tls_desc_index and next_irelative_index from reloc_count. (elf_i386_finish_dynamic_symbol): Put R_386_IRELATIVE after R_386_JUMP_SLOT. changed it back to use reloc_count again. So it is correct to use if (s != htab->elf.srelplt) s->reloc_count = 0; for both i386 and x86-64 now. 4. i386 and x86-64 use different DT_XXXs. They are handled by adding them to elf_x86_link_hash_table. With these changes, we can share _bfd_x86_elf_size_dynamic_sections in elf32-i386.c and elf64-x86-64.c. * elf32-i386.c (elf_i386_convert_load): Renamed to ... (_bfd_i386_elf_convert_load): This.
