[Chris Lattner]

Changes in directory llvm/test/Regression/Transforms/ScalarRepl:

2006-11-07-InvalidArrayPromote.ll added (r1.1)
---
Log message:

scalarrepl should not split the two elements of the vsiidx array:
int func(vFloat v0, vFloat v1) {
	int ii;
	vSInt32 vsiidx[2];
	vsiidx[0] = _mm_cvttps_epi32(v0);
	vsiidx[1] = _mm_cvttps_epi32(v1);
	ii = ((int *) vsiidx)[4];
	return ii;
}
