# Some older versions of GAS dont produce correct opcodes for the
# variants of movzx and movsx, where a 16-bit value gets expanded
# into a 32-bit value. Those GAS versions have to use the data32
# prefix, and are identified by configure with NEED_DATA32. We define
# macros here to allow for easy usage of these instructions.
