[LLVMdev] [RFC] Invariants in LLVM
...s.llvm.org/D4511 - Adds invariant awareness to LazyValueInfo (so invariants can be used by jump threading and related optimizations) http://reviews.llvm.org/D4491 - Adds basic canonicalization of the invariant intrinsics themselves (splitting invariant(a && b), etc.) http://reviews.llvm.org/D181 - This adds a scalar-evolution-powered pass, run late in the pipeline, to do more sophisticated updating of pointer alignments based on invariants. http://reviews.llvm.org/D4490 - An update to computeKnownBits and other functions in ValueTracking, and almost all callers of these functions, to use i...
