             Bug #: 15104
           Summary: [MC x86 Disassembler] MOV r/m32, imm32 not recognized

          Platform: PC
        OS/Version: Linux
            Status: NEW

          Priority: P

$ echo '0xc7 0xc2 0x00 0x00 0x00 0x00 ' | ./llvm-mc -disassemble -triple
i686-pc-linux-gnu emble -triple i686-pc-linux-gnu     
<stdin>:1:1: warning: invalid instruction encoding
0xc7 0xc2 0x00 0x00 0x00 0x00 
^

that would be "mov    $0x0,%edx" 

Opcode "0xC7" should be decoded as "MOV r/m32, imm32" instruction. But the
dissembler seems only recognize this when it follows the "mov m32 imm32"
pattern.
