* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

* [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
