+ * config/tc-i386.c (REGISTER_WARNINGS): Delete.

+ 64-bit-only warning.
+ (check_word_reg): Consistently error on mismatching register
+ size and suffix.
+ * testsuite/gas/i386/general.s: Replace dword GPR with word one
+ for movw. Replace suffix / GPR for orb.
+ * testsuite/gas/i386/inval.s: Add tests for movw with dword and
+ byte GPRs as well as ones for inb/outb with a word accumulator.

* config/tc-i386.c (operand_type_register_match): Also fall

operand. Adjust comment.
