             Bug #: 14894
           Summary: c++-analyzer does not define __SSE3__
           Product: clang
           Version: 3.2
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: giulio.eulisse at cern.ch
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Checking:

#ifdef __SSE3__                                                                 
void bar();
#endif

void
foo()
{
  bar();
}

with:

c++-analyzer -c foo.cc -msse3

triggers an error:

foo.cc:8:3: error: use of undeclared identifier 'bar'
  bar();
  ^
1 error generated.
Use of uninitialized value in concatenation (.) or string at c++-analyzer line
96.

however using __SSE2__ works just fine as expected.
