* PowerPC TPREL_HA/LO optimisationAlan Modra2020-08-242-88/+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.

* libctf, elfcpp, gold: do not assume that <byteswap.h> contains bswap_*Nick Alcock2020-06-264-46/+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.)

* [GOLD] OSABI not set when STT_GNU_IFUNC or STB_GNU_UNIQUE symbols outputAlan Modra2019-11-194-4/+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_.

| | | | | | | | | | | | An R_386_GOTOFF relocation has an addend, typically used when a symbol can be replaced by its section symbol plus an offset. psymval->value(object,0) is quite wrong then, fix it.

* PowerPC64, error on unsupported dynamic relocationAlan Modra2019-09-202-1/+6
| | | | | | | | | | | | | | | | This patch corrects the set of dynamic relocations recognised by gold as supported by glibc, and teaches ld.bfd to report an error similar to the gold error. Note that ld --noinhibit-exec can be used to produce an output, supporting older ld with newer glibc if the set of supported glibc dynamic relocations changes. bfd/ * elf64-ppc.c (ppc64_glibc_dynamic_reloc): New function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I get some spurious changes when running autoconf/automake for various projects in the tree. This is likely because they were generated using distro-patched tools last time. I ran `autoreconf -f` in the various automake projects of the binutils-gdb tree, and this is the result.

| | | | | | | | | | Relocations with right shifts were calculating wrong overflow status. Since the addr34 split-field reloc is implemented as an 18-bit high part with value shifted right by 16 and a 16-bit low part, most of the pc-relative relocs were affected. * powerpc.cc (Powerpc_relocate_functions::rela, rela_ua): Perform signed right shift for signed overflow check.
