Dimitry Andric b5e99283f4 Pull in r271548 from upstream llvm trunk (by me): ... Only attempt to detect AVG if SSE2 is available Summary: In PR29973 Sanjay Patel reported an assertion failure when a certain loop was optimized, for a target without SSE2 support. It turned out this was because of the AVG pattern detection introduced in rL253952. Prevent the assertion failure by bailing out early in `detectAVGPattern()`, if the target does not support SSE2. Also add a minimized test case. Reviewers: congh, eli.friedman, spatel Subscribers: emaste, llvm-commits Differential Revision: http://reviews.llvm.org/D20905 This should fix assertion failures ("Requires at least SSE2!") when building the games/0ad port with CPUTYPE=pentium3.
