* [DivergenceAnalysis] Separated definition of class into header.Marcello Maggioni2015-09-211-54/+25
| | | | | | | | | | | | The definition of the DivergenceAnalysis pass was in a CPP file and wasn't accessible to users of the analysis to get it through "getAnalysis<>()". This patch extracts the definition into a separate header that can be used by users of the analysis to fetch the results. Patch by Volkan Keles (vkeles@apple.com) llvm-svn: 248186

* Divergence analysis for GPU programsJingyue Wu2015-04-101-0/+337
Summary: Some optimizations such as jump threading and loop unswitching can negatively affect performance when applied to divergent branches. The divergence analysis added in this patch conservatively estimates which branches in a GPU program can diverge. This information can then help LLVM to run certain optimizations selectively.
