llvm/test/CodeGen/X86/sse42.ll
Kevin Enderby b46b03b36f Fixed the encoding problems of the crc32 instructions. All had the Operand size
override prefix and only the r/m16 forms should have had that.  Also for variant
one, the AT&T syntax, added suffixes to all forms.  Also added the missing
64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.
