// - running filter_h_avx2 transposed (one col of 32 pixels per iteration, top // to bottom) instead of scanline-ordered should be faster since then the // if (have_left) and similar conditions run only once instead of per line; // - filter_v_avx2 currently runs 16 pixels per iteration, it should be possible // to run 32 (like filter_h_avx2), and then all vpermqs can go; // - maybe split out the top/bottom filter_h_avx2 from the main body filter_h_avx2, // since then the have_left condition can be inlined; // - consider having the wrapper (wiener_filter_${ext}) also in hand-written // assembly, so the setup overhead is minimized. #define WIENER_FILTER(ext) \ \ void dav1d_wiener_filter_h_##ext(int16_t *dst, const pixel (*left)[4], \ const pixel *src, ptrdiff_t stride, \ const int16_t fh[7], const intptr_t w, \ int h, enum LrEdgeFlags edges);
