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;
}
