Recent llvm trunk is failing a few tests when ffmpeg is compiled with:
-O3 -polly -polly-vectorizer=stripmine
or
-O3 -polly
Disabling the optimizer causes the tests to pass:
-O3 -polly -polly-optimizer=none
The failing tests are:
opus-testvector01
opus-testvector05
opus-testvector06
opus-testvector07
opus-testvector08
opus-testvector09
opus-testvector10
opus-testvector11
opus-tron.6ch.tinypkts</pre>
