Bug ID: 28568
Summary: polly optimizer causes opus tests in ffmpeg to fail
Product: Polly
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Optimizer
Assignee: polly-...@googlegroups.com
Reporter: jerem...@apple.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified

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
