I've also reproduced this bug on Kubuntu 7.10 (llvm-gcc compiled with gcc 4.1.3 20070929)

Problem is discussed in previous URL. Should be fixed soon.

Here's a possible testcase:

$ cat testcase.i
typedef short __v8hi attribute((vector_size(16)));
typedef long long __m128i attribute((vector_size(16), may_alias));

static __inline __m128i
attribute((always_inline, nodebug)) _mm_or_si128(__m128i __A, __m128i __B) {
}

typedef int attribute((vector_size(16))) vSInt32;
void swapVec4ui(vSInt32 * vsi) {
vsi[0] = _mm_or_si128((__m128i) __builtin_ia32_psllwi128((__v8hi) (vsi[0]), 8),
(__m128i) __builtin_ia32_psrlwi128((__v8hi) (vsi[0]), 8));
}

$ llvm-gcc-4.2 -x c -arch i386 -msse3 -c testcase.i
