           Summary: [x86 disassembler] movs comes up blank with intel
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: X86
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: kkhoo at perfwizard.com
                CC: llvmbugs at cs.uiuc.edu

>From the "Intel® 64 and IA-32 Architectures Software Developer’s Manual
Volume 2 (2A & 2B): Instruction Set Reference, A-Z", p. 3-713:
A4 MOVS m8, m8

$ echo '0xa4'| ./llvm-mc -disassemble -triple="x86_64" -x86-asm-syntax=intel

$ echo '0xa4'| ./llvm-mc -disassemble -triple="x86_64"

This should show as "MOVS" with Intel syntax, but there's no output. AT&T
syntax looks ok.
