commit 54cab38faba72ac1bc2ccb2defd21fb78d9b5934 Author: Andreas Rheinhardt <[email protected]> AuthorDate: Mon Aug 10 18:33:09 2026 +0200 Commit: Andreas Rheinhardt <[email protected]> CommitDate: Tue Aug 11 04:35:09 2026 +0200 avutil/x86/tx_float: Don't use vextractf128 to write lower lane Just use vmovaps with an xmm register. This is faster on some systems and in any case saves codesize (by 688B).
