Sink another variable down to where its used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208913 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/Transforms/Utils/InlineFunction.cpp b/lib/Transforms/Utils/InlineFunction.cpp index 5b7a5dc88d7..e01d0c38ec4 100644 --- a/lib/Transforms/Utils/InlineFunction.cpp +++ b/lib/Transforms/Utils/InlineFunction.cpp @@ -529,13 +529,6 @@ bool llvm::InlineFunction(CallSite CS, InlineFunctionInfo &IFI, CalledFunc->isDeclaration() || // call, or call to a vararg function!
