20 # NOTE: This is a NaCl x86-64, validator specific, flag that is used to

21 # mark operands that can be used for address masking since

22 # they zero extend. It is added only if NaCl allows it for

23 # this context. See zero_extends.c for more details on this.

27 # Allow both G operand and opcode in modrm, as special case.
