However, on most machines (those with neither BYTE_LOADS_ZERO_EXTEND - nor BYTES_LOADS_SIGN_EXTEND defined), we cannot perform a + nor BYTE_LOADS_SIGN_EXTEND defined), we cannot perform a narrower operation that requested since the high-order bits will be undefined. On machine where BYTE_LOADS_*_EXTEND is defined, however, this transformation is safe as long as M1 and M2 have
