             Bug #: 13001
           Summary: SSE4.1 header don't load
           Product: clang
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: roland at utk.edu
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


test.c:
#include "smmintrin.h"

$ccc-analyzer  -c test.c -msse4.1

gives:
.../lib/clang/3.2/include/smmintrin.h:28:2: error: "SSE4.1 instruction set not
enabled"
#error "SSE4.1 instruction set not enabled"

With clang instead of ccc-analyzer it works fine. This is with checker-266. A
workaround is to add "-D __SSE4_1__"
