...be used by PolyhedralInfo pass as mentioned below. 2: Decouple DependenceInfo object from pass and create two passes. Same as above. 3: Create the interface PolyhedralInfo, which will extract Memory Access wise dependence information from Polly and provide few simple interfaces like isParallel(), isVectorizable(), tripCount(Loop&). Please feel free to post your comments and suggestions on this.

Hi Devs, I am looking at the bug https://bugs.llvm.org/show_bug.cgi?id=43953 and found that following piece of ir %arrayidx = getelementptr inbounds float, float* %Vec0, i64 %idxprom %0 = load float, float* %arrayidx, align 4, !tbaa !2 %arrayidx2 = getelementptr inbounds float, float* %Vec1, i64 %idxprom %1 = load float, float* %arrayidx2, align 4, !tbaa !2 %sub = fsub fast float %0, %1

...t;). Implemented isParallel(Loop *) interface to check parallelism of a loop. Pending Work: 1. Complete the interface - PolyhederalInfo pass. Currently I am working on providing more interfaces to check whether a loop is vectorizable or not and to get loop trip count. - isVectorizable(Loop *L, *MinDepDistance) - getLoopTripCount(Loop *) 2. Work on caching Polly's analysis results properly and provide methods to invalidate the analysis results when the SCoP changes. 3. Demonstrate the power and usefulness of the interface by integrating it...

** *Hi everyone,As you may know, stock LLVM does not provide the kind of advanced loop transformations necessary to provide good performance on many applications. LLVM's Polly project provides many of the required capabilities, including loop transformations such as fission, fusion, skewing, blocking/tiling, and interchange, all powered by state-of-the-art dependence analysis. Polly also
