           Summary: LLVM-GCC on PowerPC doesn't support the -mmmx option
           Product: new-bugs
           Version: unspecified
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: isanbard at gmail.com


For this program:

#include <mmintrin.h>

void foo()
{
  _mm_empty();
}

GCC compiles it like so:

$  gcc -arch i386 -mmmx -S t.c
$

But LLVM-GCC gives an error:

$ llvm-gcc -arch i386 -mmmx -S t.c
cc1: error: invalid option 'mmx'
$

This is almost certainly a front-end issue.
