...l optimization opportunities: - Tile bands that are 'permutable' and have at least 2 loops - Optionally vectorize the first innermost 'coincident' loop - Detect matrix-multiplication access patterns and apply a special optimization [5] H) Code Generation (IslAstInfo/CodeGeneration/PPCGCodeGeneration) Isl can transform a schedule tree representation into an AST representation, with loops and if-conditions. CodeGeneration versions the original SCoP region using the tracked assumptions and emits the AST representation. For a statement in the AST, it copies the instructions from the instruction...

** *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
