| | | | | | | PredicatePassProbability is a better name for what LikelyBranchWeight was trying to express. llvm-svn: 269999
* [Guards] Add branch metadata when loweringSanjoy Das2016-05-171-0/+10
| | | | | | | Guards are expected to basically never fail. Reflect this in the branch probabilities in their lowered form. llvm-svn: 269791
* [LowerGuardIntrinsics] Keep track of !make.implicit metadataSanjoy Das2016-04-301-0/+3
| | | | | | | | | | If a guard call being lowered by LowerGuardIntrinsics has the `!make.implicit` metadata attached, then reattach the metadata to the branch in the resulting expanded form of the intrinsic. This allows us to implement null checks as guards and still get the benefit of implicit null checks. llvm-svn: 268148

Summary: As discussed on llvm-dev[1]. This change adds the basic boilerplate code around having this intrinsic in LLVM: - Changes in Intrinsics.td, and the IR Verifier - A lowering pass to lower @llvm.experimental.guard to normal control flow - Inliner support [1]: http://lists.llvm.org/pipermail/llvm-dev/2016-February/095523.html Reviewers: reames, atrick, chandlerc, rnk, JosephTremoulet, echristo Subscribers: mcrosier, llvm-commits Differential Revision: http://reviews.llvm.org/D18527 llvm-svn: 264976
