2020-10-09[GOLD] Power10 segv due to wild r2Alan Modra2-16/+45
Calling non-pcrel functions from pcrel code requires a stub to set up r2. Gold created the stub, but an "optimisation" made the stub jump to the function local entry, ie. r2 was not initialised. This patch fixes that long branch stub problem, and another that might occur for plt call stubs to local functions. bfd/ * elf64-ppc.c (write_plt_relocs_for_local_syms): Don't do local entry offset optimisation. gold/ * powerpc.cc (Powerpc_relobj::do_relocate_sections): Don't do local entry offset optimisation for lplt_section.

2020-10-08[GOLD] Increase --split-stack-adjust-sizeAlan Modra2-1/+5
For functions with small (< 256 bytes) stack frames, the current x86 do_calls_non_split ignores --split-stack-adjust-size and, in combination with __morestack_non_split, supplies a non-split-stack function with at least 0x100000 (1M) available stack. On powerpc64, a default of 0x4000 is not large enough to reliably work with the golang testsuite. This increase the default size to the defacto x86 value. * options.h (split_stack_adjust_size): Default to 0x100000.

2020-08-24PowerPC TPREL_HA/LO optimisationAlan Modra2-88/+181
ppc64 ld optimises sequences like the following addis 3,13,wot@tprel@ha lwz 3,wot@tprel@l(3) to nop lwz 3,wot@tprel(13) when "wot" is located near enough to the thread pointer. However, the ABI doesn't require that R_PPC64_TPREL16_HA always be on an addis rt,13,imm instruction, and while ld checked for that on the high-part instruction it didn't disable the optimisation on the low-part instruction. This patch fixes that problem, disabling the tprel optimisation globally if high-part instructions don't pass sanity checks. The optimisation is also enabled for ppc32, where before ld.bfd had the code in the wrong place and ld.gold had it in a block only enabled for ppc64. bfd/ * elf32-ppc.c (ppc_elf_check_relocs): Set has_tls_reloc for high part tprel16 relocs.

2020-06-26libctf, elfcpp, gold: do not assume that <byteswap.h> contains bswap_*Nick Alcock4-46/+102
At least one C library (uclibc-ng) defines some of these only when the compiler is GCC. We might as well test for all three cases and handle any of them being missing. Very similar code exists in libctf and split between elfcpp and gold: fix both. (Also sync up elfcpp with a change made to libctf swap.h a few months ago: since there is no out-of-line definition of the bswap replacements, they should be declared static inline, not just inline, to prevent the linker generating out-of-line references to them.)

2019-11-19[GOLD] OSABI not set when STT_GNU_IFUNC or STB_GNU_UNIQUE symbols outputAlan Modra4-4/+52
This patch arranges to have OSABI set to ELFOSABI_GNU (if not set to some other non-zero value) when gold outputs an ifunc local or global symbol, or a unique global symbol to either .dynsym or .symtab. STT_GNU_IFUNC and STB_GNU_UNIQUE have values in the LOOS to HIOS range and therefore require interpretation according to OSABI. I'm not sure why parameters->target() is const Target& while parameters->sized_target() is Sized_target*, but it's inconvenient to use the latter in Symbol_table::finalize. So this patch adds another const_cast complained about in layout.cc and gold.cc. PR 24853 * symtab.h (set_has_gnu_output, has_gnu_output_): New. * symtab.cc (Symbol_table::Symbol_table): Init has_gnu_output_. (Symbol_table::finalize): Set ELFOSABI_GNU when has_gnu_output_.
