From 46c5f79789947b75ff3b0cc107f133fb0c5ffb5e Mon Sep 17 00:00:00 2001 From: Nadav Rotem Date: Tue, 4 Dec 2012 23:25:24 +0000 Subject: LoopVectorizer: Increase the number of pointers that can be tested at runtime. If we cant prove statically that the pointers are disjoint then we add the runtime check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169334 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Vectorize/LoopVectorize.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/Transforms/Vectorize/LoopVectorize.cpp') diff --git a/lib/Transforms/Vectorize/LoopVectorize.cpp b/lib/Transforms/Vectorize/LoopVectorize.cpp index 20e073b1b9..166ad33cac 100644 --- a/lib/Transforms/Vectorize/LoopVectorize.cpp +++ b/lib/Transforms/Vectorize/LoopVectorize.cpp @@ -90,7 +90,7 @@ const unsigned TinyTripCountThreshold = 16; /// When performing a runtime memory check, do not check more than this /// number of pointers.
