            Bug ID: 17471
           Summary: -x86-asm-syntax parameter is not respected by llvm-mc
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: kkhoo at perfwizard.com

$ ./llvm-mc -help
OVERVIEW: llvm machine code playground
...
  -x86-asm-syntax                  - Choose style of code to emit from X86
backend:
    =att                           -   Emit AT&T-style assembly
    =intel                         -   Emit Intel-style assembly

$ echo '0x8f 0x00' | ./llvm-mc -disassemble -triple=x86_64 -x86-asm-syntax=att
    .text
    popq    (%rax)
$ echo '0x8f 0x00' | ./llvm-mc -disassemble -triple=x86_64
-x86-asm-syntax=intel
    .text
    popq    (%rax)


The expected output with Intel syntax should be something like:
    pop    qword ptr [rax]


This is with:
$ ./llvm-mc -version
LLVM (http://llvm.org/):
  LLVM version 3.4svn
  DEBUG build with assertions.
  Built Oct  3 2013 (11:08:29).
