For add %reg1, name@gottpoff(%rip), %reg2 and add name@gottpoff(%rip), %reg1, %reg2 add #define R_X86_64_CODE_6_GOTTPOFF 50 if the instruction starts at 6 bytes before the relocation offset. They are similar to R_X86_64_GOTTPOFF. Linker can covert GOTTPOFF to add $name@tpoff, %reg1, %reg2 Rewrite fx_tcbit, fx_tcbit2 and fx_tcbit3 usage to generate R_X86_64_GOTPCRELX, R_X86_64_REX_GOTPCRELX, R_X86_64_CODE_4_GOTPCRELX, R_X86_64_CODE_4_GOTTPOFF, R_X86_64_CODE_4_GOTPC32_TLSDESC and R_X86_64_CODE_6_GOTTPOFF. NB: There is no need to check BFD_RELOC_X86_64_CODE_4_GOTTPOFF in md_assemble since there is only BFD_RELOC_X86_64_GOTTPOFF at this stage, which will be converted to BFD_RELOC_X86_64_CODE_4_GOTTPOFF or BFD_RELOC_X86_64_CODE_6_GOTTPOFF in i386_validate_fix. 5 relocations: #define R_X86_64_CODE_5_GOTPCRELX 46 #define R_X86_64_CODE_5_GOTTPOFF 47 #define R_X86_64_CODE_5_GOTPC32_TLSDESC 48 #define R_X86_64_CODE_6_GOTPCRELX 49 #define R_X86_64_CODE_6_GOTPC32_TLSDESC 51 are added for completeness and they are unused. bfd/ * elf64-x86-64.c (x86_64_elf_howto_table): Add R_X86_64_CODE_5_GOTPCRELX, R_X86_64_CODE_5_GOTTPOFF, R_X86_64_CODE_5_GOTPC32_TLSDESC, R_X86_64_CODE_6_GOTPCRELX, R_X86_64_CODE_6_GOTTPOFF and R_X86_64_CODE_6_GOTPC32_TLSDESC.
