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. (ppc_elf_tls_optimize): Sanity check high part tprel16 relocs. Clear do_tls_opt on odd instructions. (ppc_elf_relocate_section): Move TPREL16_HA/LO optimisation later. Don't sanity check them here. * elf64-ppc.c (ppc64_elf_check_relocs): Set has_tls_reloc for high part tprel16 relocs. (ppc64_elf_tls_optimize): Sanity check high part tprel16 relocs. Clear do_tls_opt on odd instructions. (ppc64_elf_relocate_section): Don't sanity check TPREL16_HA. ld/ * testsuite/ld-powerpc/tls32.d: Update for TPREL_HA/LO optimisation. * testsuite/ld-powerpc/tlsexe32.d: Likewise. * testsuite/ld-powerpc/tlsldopt32.d: Likewise. * testsuite/ld-powerpc/tlsmark32.d: Likewise. * testsuite/ld-powerpc/tlsopt4_32.d: Likewise. * testsuite/ld-powerpc/tprel.s, * testsuite/ld-powerpc/tprel.d, * testsuite/ld-powerpc/tprel32.d: New tests. * testsuite/ld-powerpc/tprelbad.s, * testsuite/ld-powerpc/tprelbad.d: New test. * testsuite/ld-powerpc/powerpc.exp: Run them. gold/ * powerpc.cc (Target_powerpc): Add tprel_opt_ and accessors.
