Comment 2 ernsteiswuerfel archtester 2019-12-03 00:15:46 UTC
Out of curiosity I run the full testsuite (built v1.8.1 from upstream git) and reported the bug upstream.

Comment 3 Rolf Eike Beer archtester 2021-06-12 18:30:06 UTC
The alignment test also shows that this doesn't handle alignment properly as seen on sparc:

    media-libs/libvpx: add 1.11.0
    
    Notably now forcing specific targets only where we
    know libvpx works well and otherwise using
    the generic implementation due to
    runtime breakage (and extensive test failures).

    media-libs/libvpx: drop to ~sparc
    
    Too many test failures. Unclear if it truly works at runtime.

Comment 9 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-05-11 00:50:41 UTC
ernsteiswuerfel, does it work OK at runtime or should we try drop it somehow for stable ppc?
