Subject: [chunkset_neon] Don't use signed vector types.
X-Git-Tag: 2.1.0-beta1~560
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=46af2953a7b79904bb3a9e143ad66564a1d6d0eb;p=thirdparty%2Fzlib-ng.git

[chunkset_neon] Don't use signed vector types.
* There is no need to convert between unsigned and signed vector types. All relevant intrinsics have versions for all unsigned vector types.
