Subject: [FFmpeg-devel] [PATCH] tests/checkasm/checkasm: Don't test 3dnow (PR #21120)
Date: Sun, 07 Dec 2025 16:09:09 -0000
Message-ID: <176512374988.39.18093802134609659579@2cb04c0e5124> (raw)
PR #21120 opened by mkver
URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/21120
Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/21120.patch
The last 3dnow functions have been removed in commit
5ef613bcb0508f16bd5b190168183326391de9b0, so don't test
it in checkasm.
(This will affect only one test, namely scalarproduct_and_madd_int16
from lossless_audiodsp: It does not use an SSSE3 function when
the 3dnow flag is set. So for old AMDs (which advertise support for
3dnow), said SSSE3 function is never tested. Now it will.)
