From a8f026e2d4e2e0dfc32d027ef69fafc963fd2208 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. llvm-svn: 169334 --- llvm/lib/Transforms/Vectorize/LoopVectorize.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'llvm/lib/Transforms/Vectorize/LoopVectorize.cpp') diff --git a/llvm/lib/Transforms/Vectorize/LoopVectorize.cpp b/llvm/lib/Transforms/Vectorize/LoopVectorize.cpp index 20e073b1b94..166ad33cac4 100644 --- a/llvm/lib/Transforms/Vectorize/LoopVectorize.cpp +++ b/llvm/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.
