2019-09-05PowerPC64 GOT_PCREL relocsAlan Modra2-53/+31
PC-relative relocs typically use the addend in adjusting what they are relative to. For example: bcl 20,31,1f 1: mflr 12 addi 12,12,xxx-1b generates "R_PPC64_REL16 xxx+0x4" for the addi (when little-endian). The addend reflects the fact that you want the offset relative to the previous insn not the current one in this case. So the question is, will we ever want to do something like that for an instruction using R_PPC64_GOT_PCREL34? I thought so at the time I first implemented support in ld but at the time I think the hardware was possibly going to support pcrel+offset+reg addressing. In which case you might want something like: load_big_offset_into_r2 pld 3,sym-big_offset@got@pcrel(2) which would be a way of supporting more than 8G offsets from code to the GOT. We could do the same with load_big_offset_into_r2 pla 9,sym-big_offset@got@pcrel ldx 3,9,2 However, this is really a poor version of TOC-pointer relative code. So let's go with an addend on R_PPC64_GOT_PCREL34 meaning that sym+addend should be put in a GOT entry, and the relocation calculate the pc-relative offset to that GOT entry. Note that this is an extension to the ABI, which says (by the expression given for GOT relocs) that non-zero addends on GOT and PLT relocs are ignored. This is true for all GOT/PLT relocs, not just the pcrel ones. * elf64-ppc.c (ppc64_elf_check_relocs): Interpret an addend in GOT_PCREL and PLT_PCREL relocs as affecting the value stored in the GOT/PLT entry rather than affecting the offset to that GOI/PLT entry.

2019-08-28RISC-V: Fix a gp relaxation reloc overflow error.Jim Wilson2-7/+16
This was broken when I changed how we compute the value for the gp register. It used to be computed inside the sdata section. Now it is computed at the end which makes it an abs section symbol. There is code that tries to use the alignment of the section that the gp value is in, but this does not work if it is in the abs section, as the abs section has alignment of 1 byte. There are people using alternative linker scripts that still define it in the sdata section, so the code is still useful. Thus adding a check to disable this when gp is in the abs section. bfd/ * elfnn-riscv.c (_bfd_riscv_relax_lui): Add check to exclude abs section when setting max_alignment. Update comment.

2019-08-29PR24891, objdump memory leaks when parsing malformed archiveAlan Modra4-3/+24
BFD was leaking memory in bfd_check_format_matches. As part of deciding the proper format of an archive, BFD looks at the format of the first file stored. That file's bfd was left open for reasons given in a comment removed in git commit 0e71e4955cd1 that said: /* We ought to close `first' here, but we can't, because we have no way to remove it from the archive cache. It's close to impossible to figure out when we can release bfd_ardata. FIXME. */ Well, things have changed since that comment was true and we now can remove files from the archive cache. Closing the first file is good and cures some of the leaks. Other leaks are caused by bfd_check_format_matches throwing away bfd tdata before trying a new match. That lost the element cache set up when format checking the first element in the archive. The easiest and cleanest fix is to simply disable the caching when checking the first element. PR 24891 * bfd.c (struct bfd): Add no_element_cache. * archive.c (_bfd_get_elt_at_filepos): Don't add element to archive cache when no_element_cache.

2019-08-22AArch64: Fix LD crash on weak and undefined TLS symbols. (PR/24602).Tamar Christina4-23/+88
This patch fixes a few linker crashes due to TLS code reaching an assert when it shouldn't. The first scenario is with weak TLS symbols that remain weak during linking. In this case the mid-end would not have seen a TLS symbol and so wouldn't have allocated the TLS section. We currently assert here and the linker crashes with a not very useful message. This patch changes this to return the value 0 for the TLS symbol in question emulating what lld and gold and other BFD targets do. However because weak TLS is implementation defined and we don't define any behavior for it I also emit a warning to the user to inform them of such. Secondly when a strong TLS reference is undefined. The linker crashes even after it correctly reported that there is an undefined reference. This changes it so that it gracefully exits and reports a useful error. bfd/ChangeLog: PR ld/24601 * elfnn-aarch64.c (aarch64_relocate): Handle weak TLS and undefined TLS.

2019-08-22ARM CMSE symbolsAlan Modra2-20/+14
This patch removes use of st_target_internal to cache the result of comparing symbol names against CMSE_PREFIX. The problem with setting a bit in st_target_internal in swap_symbol_in is that calling bfd_elf_sym_name from swap_symbol_in requires symtab_hdr, and you don't know for sure whether swap_symbol_in is operating on dynsyms (and thus elf_tdata (abfd)->dynsymtab_hdr should be used) or on the normal symtab (thus elf_tdata (abfd)->symtab_hdr). You can make an educated guess based on abfd->flags & DYNAMIC but that relies on knowing a lot about calls to bfd_elf_get_elf_syms, and is fragile in the face of possible future changes. include/ * elf/arm.h (ARM_GET_SYM_CMSE_SPCL, ARM_SET_SYM_CMSE_SPCL): Delete. bfd/ * elf32-arm.c (cmse_scan): Don't use ARM_GET_SYM_CMSE_SPCL, instead recognize CMSE_PREFIX in symbol name.

2019-08-19Fix N^2 behavior in _bfd_dwarf2_find_symbol_biasTom Tromey2-10/+51
A customer reported a case where addr2line was very slow. We tracked this down to some N^2 behavior in _bfd_dwarf2_find_symbol_bias in the unusual case where no function can be found. This patch fixes the bug, and reduces the runtime for a particular request from 127 seconds to 1 second. bfd/ChangeLog 2019-08-19 Tom Tromey <tromey@adacore.com> * dwarf2.c (_bfd_dwarf2_find_symbol_bias): Create hash table holding symbols.
2019-08-19PowerPC64 ha/lo insn checksAlan Modra2-72/+109
These are done in ppc64_elf_edit_toc, which now also garbage collects unused GOT entries. The checks for legitimate instructions weren't being done for the GOT relocs, unless the file also happened to have a toc section. * elf64-ppc.c (struct ppc64_elf_obj_tdata): Rename has_gotrel to has_optrel. (struct _ppc64_elf_section_data): Likewise. (ppc64_elf_check_relocs): Set has_optrel for more relocs. (ppc64_elf_edit_toc): Do ha/lo insn checks in GOT loop rather than TOC loop. Check PLT16 insns too.
