Hi folks, cool project!
I was trying out a few of my code snippets but can't seem to get them to work. Here's an example:
#include <x86intrin.h>
__m512 huge = _mm512_set1_pd(2);
__m512 tiny = _mm512_set1_pd(-2);
__m512 one = _mm512_set1_pd(1.0);
void sgm(__m512& prodv, __m512& scales, __m512 const incoming) {
prodv = _mm512_mul_pd(prodv, incoming);
auto pgeh = _mm512_cmp_pd_mask(prodv, huge, _CMP_GE_OQ);
auto plet = _mm512_cmp_pd_mask(prodv, tiny, _CMP_LE_OQ);
prodv = _mm512_mask_mul_pd(prodv, pgeh, prodv, tiny);
prodv = _mm512_mask_mul_pd(prodv, plet, prodv, huge);
scales = _mm512_mask_add_epi64(scales, pgeh, scales, one);
scales = _mm512_mask_sub_epi64(scales, plet, scales, one);
}Removing the & in the parameter list and making it return prodv gets it a bit further, but not much. All of the instructions are reported as "unsupported command".
