Gold: Handle R_X86_64_CODE_4_GOTPC32_TLSDESC/R_X86_64_CODE_4_GOTTPOFF
Handle R_X86_64_CODE_4_GOTTPOFF and R_X86_64_CODE_4_GOTPC32_TLSDESC.
Convert
add name@gottpoff(%rip), %reg
mov name@gottpoff(%rip), %reg
to
add $name@tpoff, %reg
mov $name@tpoff, %reg
and
lea name@tlsdesc(%rip), %reg
to
mov $name@tpoff, %reg
mov name@gottpoff(%rip), %reg
if the instruction is encoded with the REX2 prefix when possible.
