See `llvm/docs/README.txt` for more information. - Loop Vectorizer - --------------- - We've continued the work on the loop vectorizer. The loop vectorizer now has the following features: - # Loops with unknown trip count. - # Runtime checks of pointers - # Reductions, Inductions - # If Conversion - # Pointer induction variables - # Reverse iterators - # Vectorization of mixed types - # Vectorization of function calls - # Partial unrolling during vectorization - - We've also improved the X86 and ARM cost model. - - TargetTransformInfo - ------------------- - TargetTransformInto (TTI) is a new interface that can be used by IR-level passes - to obtain target-specific information, such as the costs of instructions.
