For add name@gottpoff(%rip), %reg mov name@gottpoff(%rip), %reg add # define R_X86_64_CODE_4_GOTTPOFF 44 and for lea name@tlsdesc(%rip), %reg add # define R_X86_64_CODE_4_GOTPC32_TLSDESC 45 if the instruction starts at 4 bytes before the relocation offset. They are similar to R_X86_64_GOTTPOFF and R_X86_64_GOTPC32_TLSDESC, respectively. Linker can covert GOTTPOFF to add $name@tpoff, %reg mov $name@tpoff, %reg and GOTPC32_TLSDESC to mov $name@tpoff, %reg mov name@gottpoff(%rip), %reg if the instruction is encoded with the REX2 prefix when possible. bfd/ * elf64-x86-64.c (x86_64_elf_howto_table): Add R_X86_64_CODE_4_GOTTPOFF and R_X86_64_CODE_4_GOTPC32_TLSDESC. (R_X86_64_standard): Updated. (x86_64_reloc_map): Add BFD_RELOC_X86_64_CODE_4_GOTTPOFF and BFD_RELOC_X86_64_CODE_4_GOTPC32_TLSDESC.

(md_assemble): Handle BFD_RELOC_X86_64_CODE_4_GOTTPOFF. (output_insn): Don't add empty REX prefix with REX2 prefix. (output_disp): Handle BFD_RELOC_X86_64_CODE_4_GOTTPOFF and BFD_RELOC_X86_64_CODE_4_GOTPC32_TLSDESC. (md_apply_fix): Likewise. (i386_validate_fix): Generate BFD_RELOC_X86_64_CODE_4_GOTTPOFF or BFD_RELOC_X86_64_CODE_4_GOTPC32_TLSDESC if ixp->fx_tcbit3 is set. (tc_gen_reloc): Handle BFD_RELOC_X86_64_CODE_4_GOTTPOFF and BFD_RELOC_X86_64_CODE_4_GOTPC32_TLSDESC. * testsuite/gas/i386/x86-64-gottpoff.d: New file. * testsuite/gas/i386/x86-64-gottpoff.s: Likewise. * testsuite/gas/i386/x86-64-tlsdesc.d: Likewise. * testsuite/gas/i386/x86-64-tlsdesc.s: Likewise. include/ * elf/x86-64.h (elf_x86_64_reloc_type): Add R_X86_64_CODE_4_GOTTPOFF and R_X86_64_CODE_4_GOTPC32_TLSDESC ld/ * testsuite/ld-x86-64/tlsbindesc.d: Updated. * testsuite/ld-x86-64/tlsbindesc.rd: Likewise. * testsuite/ld-x86-64/tlsbindesc.s: Add R_X86_64_CODE_4_GOTTPOFF and R_X86_64_CODE_4_GOTPC32_TLSDESC tests. |
