@ -527,33 +527,6 @@ Add hooks to commute some CMPP operations.
//===---------------------------------------------------------------------===//
Implement some missing insert/extract element operations without going through
the stack. Testcase here:
CodeGen/X86/vec_ins_extract.ll
corresponds to this C code:
typedef float vectorfloat __attribute__((vector_size(16)));
void test(vectorfloat *F, float f) {
vectorfloat G = *F + *F;
*((float*)&G) = f;
*F = G + G;
}
void test2(vectorfloat *F, float f) {
vectorfloat G = *F + *F;
((float*)&G)[2] = f;
*F = G + G;
}
void test3(vectorfloat *F, float *f) {
vectorfloat G = *F + *F;
*f = ((float*)&G)[2];
}
void test4(vectorfloat *F, float *f) {
vectorfloat G = *F + *F;
*f = *((float*)&G);
}
//===---------------------------------------------------------------------===//
Apply the same transformation that merged four float into a single 128-bit load
to loads from constant pool.
