[LLVMdev] Loop-specific optimizations
...ion. We do this in the front end already: void test_noise(int x, int* in, int* out) { __attribute__((noise("inline(fn) licm wfv-vectorize(4) unroll(4)"))) for (int i=0; i<16; ++i) { out[i] = in[i] + fn(x); } } This results in IR similar to this code: void test_noise_result(int x, int* in, int* out) { // Code of "fn" (assuming it was loop invariant). int F = ... out[0-3] = <in[0],in[1],in[2],in[3]> + <F,F,F,F>; out[4-7] = <in[4],in[5],in[6],in[7]> + <F,F,F,F>; out[8-11] = <in[8],in[9],in[10],in[11]> + <F,...

That definitely sounds interesting. Do you add these attributes to
