Subject: [PATCH v4 0/2] xor-neon: Remove GCC warn & pragmas
Date: Tue, 19 Jan 2021 15:17:22 +0200 [thread overview]
Message-ID: <20210119131724.308884-1-adrian.ratiu@collabora.com> (raw)
Dear all,
In v4 a Clang-specific vectorization warning was added at
Arnd suggestion.
This series does not address the Clang vectorize not working
bug itself which is a known pre-existing issued documented
at [1] [2] [3]. Clang vectorization needs to be investigated
in more deepth and fixed separately. The purpouse of this is
to only fix some low-hanging-fruit GCC related isues.
Tested on next-20210118 using GCC 10.2.0 and Clang 10.0.1.

Kind regards,
Adrian
