Changes in directory llvm/test/Regression/Transforms/ScalarRepl:
vector_promote.ll added (r1.1)
---
Log message:
New testcase, checking to see we can turn this code:
void test(vector float *F, float f) {
vector float G = *F + *F;
*((float*)&G) = f;
*F = G + G;
}
void test2(vector float *F, float f) {
vector float G = *F + *F;
((float*)&G)[2] = f;
*F = G + G;
}
void test3(vector float *F, float *f) {
vector float G = *F + *F;
*f = ((float*)&G)[2];
}
void test4(vector float *F, float *f) {
vector float G = *F + *F;
*f = *((float*)&G);
}
into insert/extract element operations with no memory traffic.
