For mov name@GOTPCREL(%rip), %reg test %reg, name@GOTPCREL(%rip) binop name@GOTPCREL(%rip), %reg where binop is one of adc, add, add, cmp, or, sbb, sub, xor instructions, add # define R_X86_64_CODE_4_GOTPCRELX 43 if the instruction starts at 4 bytes before the relocation offset. It similar to R_X86_64_GOTPCRELX. Linker can treat R_X86_64_CODE_4_GOTPCRELX as R_X86_64_GOTPCREL or convert the above instructions to lea name(%rip), %reg mov $name, %reg test $name, %reg binop $name, %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_GOTPCRELX. (R_X86_64_standard): Updated. (x86_64_reloc_map): Add BFD_RELOC_X86_64_CODE_4_GOTPCRELX. (elf_x86_64_convert_load_reloc): Handle R_X86_64_CODE_4_GOTPCRELX. (elf_x86_64_scan_relocs): Likewise.

(i386_validate_fix): Generate BFD_RELOC_X86_64_CODE_4_GOTPCRELX if fixp->fx_tcbit3 is set. * config/tc-i386.h (TC_FORCE_RELOCATION_LOCAL): Add BFD_RELOC_X86_64_CODE_4_GOTPCRELX.
