Subject: [FFmpeg-devel] [PATCH] avcodec/x86/vp9: Add AVX-512ICL for 16x16 and 32x32 8bpc inverse transforms
Date: Sat, 17 May 2025 00:59:31 +0200

Placed in a new separate file as the existing combined MMX/SSE/AVX
file is humongous and takes forever to assemble as is.
This adds ~16 KiB of .text. The existing 8bpc asm is ~240 KiB of which
the corresponding AVX2 functions makes up ~42 KiB.
Tested to pass FATE on Linux and Windows.
Checkasm numbers vs AVX2 on Zen 5 (Strix Halo):
vp9_inv_adst_adst_16x16_sub16_add_8_avx2: 209.3
vp9_inv_adst_adst_16x16_sub16_add_8_avx512icl: 99.5
