--- Comment #6 from Eric Christopher <echristo at gmail.com> ---
I fixed this a while back:

echristo-macbookpro2:~/tmp> cat foo.c
#include <smmintrin.h>

int main(int argc, char** argv)
{
  __m128 y = _mm_set1_ps(argc);
  y = _mm_blendv_ps(y, y, y);
  return y[0];
}
echristo-macbookpro2:~/tmp> ~/builds/build-llvm/Debug+Asserts/bin/clang++ -flto
-msse4.1 foo.c
clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is
deprecated
