H.J. Lu 56ceb5b540 Add R_X86_64_[REX_]GOTPCRELX support to gas and ld ... This patch adds support for the R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 to gas and ld. It updates gas to generate R_X86_64_GOTPCRELX, R_X86_64_REX_GOTPCRELX if there is a REX prefix, relocation for memory operand, foo@GOTPCREL(%rip). With the locally defined symbol, foo, we convert mov foo@GOTPCREL(%rip), %reg to lea foo(%rip), %reg and convert call/jmp *foo@GOTPCREL(%rip) to nop call foo/jmp foo nop When PIC is false, convert test %reg, foo@GOTPCREL(%rip) to test $foo, %reg and convert binop foo@GOTPCREL(%rip), %reg to binop $foo, %reg where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions. bfd/ * elf64-x86-64.c: Include opcode/i386.h.
