2017-11-07ngettext supportAlan Modra3-23/+51
binutils has lacked proper pluralization of output messages for a long time, for example, readelf will display information about a section that "contains 1 entries" or "There are 1 section headers". Fixing this properly requires us to use ngettext, because other languages have different rules to English. This patch defines macros for ngettext and friends to handle builds with --disable-nls, and tidies the existing nls support. I've redefined gettext rather than just defining "_" as dgettext in bfd and opcodes in case someone wants to use gettext there (which might conceivably happen with generated code). bfd/ * sysdep.h: Formatting, comment fixes.

2017-11-05Proper bound check in _bfd_doprnt_scanAlan Modra2-6/+12

2017-11-05PR22397, BFD internal error when message locale isn't CAlan Modra2-31/+317
This adds positional parameter support to the bfd error handler, something that was lost 2017-04-13 when _doprnt was added with commit c08bb8dd. The number of format args is now limited to 9, which is sufficient for current _bfd_error_handler messages.

2017-11-05hppa-linux TLS relocsAlan Modra2-111/+170
This patch fixes various problems with TLS relocations. 1) Report an error if a symbol has both TLS and normal GOT entries. 2) The GOT entry size calculation was obscure and made use of the fact that a symbol shouldn't have both normal and TLS GOT entries. 3) The second word of a GD GOT entry sometimes omitted a dynamic reloc, which was fine except that doing so makes it impossible for ld.so to differentiate GD and LD entries. Also, a NONE reloc was emitted. 4) Unnecessary relocs were emitted for GOT entries. 5) GOT relocs didn't take note of UNDEFWEAK_NO_DYNAMIC_RELOC. * elf32-hppa.c (enum _tls_type): Move.

2017-11-05PR22394, hppa-linux-ld fails to emit dynamic relocationsAlan Modra2-37/+94
gcc -mfast-indirect-calls emits a function pointer initialization without a P% (plabel) modifier. ld does not create the necessary dynamic relocations for this to work. It turns out that the problem is caused by the non_got_ref symbol flag. This flag is set for non-pic by check_relocs to indicate that the symbol might need copy relocations or dynamic relocations. Later, the backend adjust_dynamic_symbol clears the flag to indicate dynamic relocations are needed, but leaves it set when copy relocations were created. The inversion in meaning is insane, but it's that way because the backend adjust_dynamic_symbol function doesn't get to look at all symbols.. Anyway, the insanity works for non-function symbols. However, the flag is left set on any function symbol with a dynamic relocation. This patch fixes the non_got_ref handling for function symbols, adds -z nocopyreloc for hppa-elf, reports where textrel occurs, and expands comments. The check_relocs change just stops creation of dyn_relocs we always threw away later. PR 22394 * elf32-hppa.c (elf32_hppa_check_relocs): Don't create dyn_relocs for plabels when non-pic.

I noticed when looking at pr22300 that before calling check_relocs we have an elf_object_id test (added for pr11933) as well as the relocs_compatible test. I believe backend gc_mark_hook and gc_sweep_hook ought to be protected similarly from being confused by unexpected relocations (for example, both elf64-ppc.c and elf32-ppc.c use _bfd_elf_relocs_compatible, so I think it would be possible for the ppc64 gc_mark_hook to be presented with a ppc32 relocatable object). * elflink.c (elf_gc_sweep): Test elf_object_id in addition to relocs_compatible.

2017-10-28PR22300, Abort in elf32_hppa_relocate_section building polymlAlan Modra5-5/+11
polyml produces object files with the wrong OS/ABI for hppa-linux. This, along with the fact that elf32-hppa.c is using the strictest backend relocs_compatible, results in wrong merging of ELF symbols. So, remove the relocs_compatible check in _bfd_elf_merge_symbol. _bfd_elf_merge_symbol is only called nowadays from within blocks protected by is_elf_hash_table, so "we are doing an ELF link" as the removed comment says, is true. Also relax relocs_compatible for hppa and powerpc. relocs_compatible is used for more than just merging symbols, as the name suggests. This allows objects that are in fact reasonably compatible to be linked.

2017-10-23MIPS: Preset EF_MIPS_ABI2 with n32 ELF objectsMaciej W. Rozycki2-1/+25
Fix a bug in MIPS n32 ELF object file generation and make such objects consistent with the n32 BFD requested, by presetting the EF_MIPS_ABI2 flag in the `e_flags' member of the newly created ELF file header, as it is this flag that tells n32 objects apart from o32 objects. This flag will then stay set through to output file generation for writers such as GAS or GDB's `generate-core-file' command. Readers will overwrite the whole of `e_flags' along with the rest of the ELF file header in `elf_swap_ehdr_in' and then verify in `mips_elf_n32_object_p' that the flag is still set before accepting an input file as an n32 object.

2017-10-19RISC-V: Relax RISCV_PCREL_* to RISCV_GPREL_*Palmer Dabbelt2-7/+297
In the medany code model the compiler generates PCREL_HI20+PCREL_LO12 relocation pairs against local symbols because HI20+LO12 relocations can't reach high addresses. We relax HI20+LO12 pairs to GPREL relocations when possible, which is an important optimization for Dhrystone. Without this commit we are unable to relax PCREL_HI20+PCREL_LO12 pairs to GPREL when possible, causing a 10% permormance hit on Dhrystone on Rocket. Note that we'll now relax la gp, __global_pointer$ to mv gp, gp which probably isn't what you want in your entry code. Users who want gp-relative symbols to continue to resolve should add ".option norelax" accordingly. Due to this, the assembler now pairs PCREL relocations with RELAX relocations when they're expected to be relaxed just like every other relaxable relocation. bfd/ChangeLog 2017-10-19 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv.c (riscv_pcgp_hi_reloc): New structure.

2017-10-19RISC-V: Add R_RISCV_DELETE, which marks bytes for deletionPalmer Dabbelt2-3/+40
We currently delete bytes by shifting an entire BFD backwards to overwrite the bytes we no longer need. The result is that relaxing a BFD is quadratic time. This patch adds an additional relocation that specifies a byte range that will be deleted from the final object file, and adds a relaxation pass (between the existing passes that delete bytes and the alignment pass) that actually deletes the bytes. Note that deletion is still quadratic time, and nothing uses R_RISCV_DELETE yet. I've been meaning to go convert all the other relaxations to use R_RISCV_DELETE and then make it faster, but this patch has been sitting around for months so it looks like that won't happen for a bit. The PCREL->GPREL relaxation that comes next uses this, and since we've been using these two patches out of tree since I wrote them months ago I figure it's better to just get them in now. I (or someone else :)) can convert all the relocations later... R_RISCV_DELETE will never be emitted into ELF objects, so therefor isn't exposed to the rest of binutils. As such, we're not considering this as part of the ABI. bfd/ChangeLog 2017-10-19 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv (R_RISCV_DELETE): New define.
