From 8e0d1c03ca7fd86e6879b4e37d0d7f0e982feef6 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Wed, 29 Aug 2012 15:32:21 +0000 Subject: Make MemoryBuiltins aware of TargetLibraryInfo. This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162841 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Scalar/JumpThreading.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/Transforms/Scalar/JumpThreading.cpp') diff --git a/lib/Transforms/Scalar/JumpThreading.cpp b/lib/Transforms/Scalar/JumpThreading.cpp index dd42c59059..20844c6cd5 100644 --- a/lib/Transforms/Scalar/JumpThreading.cpp +++ b/lib/Transforms/Scalar/JumpThreading.cpp @@ -1455,7 +1455,7 @@ bool JumpThreading::ThreadEdge(BasicBlock *BB, // At this point, the IR is fully up to date and consistent.
