commit 3a1e63e007f1906ba23ca145f5ebd04ee094b768 Author: Andreas Rheinhardt <[email protected]> AuthorDate: Thu Mar 19 14:38:57 2026 +0100 Commit: Andreas Rheinhardt <[email protected]> CommitDate: Mon Mar 30 13:51:53 2026 +0200 avcodec/x86/vvc/alf: Avoid zeroing unnecessarily In case of >8bpp, there is already a zero register available (for clipping); in case of Unix64, one can simply use an unused register. Doing so reduces codesize.
