x86: limit RegRex64 use The special property really only applies to the "extended" byte regs having legacy word/dword counterparts. While touching involved code also drop redundant byte checks from a conditional in establish_rex(): The other remaining RegRex64 uses only exist on registers which can't be used as register operands anyway. Hence RegRex64 as an attribute of a (valid) register operand implies that it's a byte reg.
