I get fate error related to the patch: make fate-checkasm-vf_gblur checkasm: using random seed 227700911 SSE: - vf_gblur.postscale_slice [OK] SSE4.1: - vf_gblur.horiz_slice [OK] test failed comparing 297.388 with 190 (abs diff=107.388 with EPS=0.01) AVX2: horiz_slice_avx2 (vf_gblur.c:47) - vf_gblur.horiz_slice [FAILED] - vf_gblur.postscale_slice [OK] src/tests/fate-run.sh: line 78: 40217 Illegal instruction: 4 $target_exec $target_path/"$@“ The last one "Illegal instruction: 4” exist before the patch. I have tested on two macbook: mbp 2015 and MacBook Pro (16-inch, 2019).
