Andrew Trick c7b0b7dc8f Add support to indvars for optimizing sadd.with.overflow. ... Split sadd.with.overflow into add + sadd.with.overflow to allow analysis and optimization. This should ideally be done after InstCombine, which can perform code motion (eventually indvars should run after all canonical instcombines). We want ISEL to recombine the add and the check, at least on x86. This is currently under an option for reducing live induction variables: -liv-reduce. The next step is reducing liveness of IVs that are live out of the overflow check paths. Once the related optimizations are fully developed, reviewed and tested, I do expect this to become default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197926 91177308-0d34-0410-b5e6-96231b3b80d8		2013-12-23 23:31:49 +00:00
