From 6cb8c23db1c3becdce6dfbf1b7f1677faca4251e Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Thu, 26 Aug 2010 15:41:53 +0000 Subject: Reapply r112091 and r111922, support for metadata linking, with a fix: add a flag to MapValue and friends which indicates whether any module-level mappings are being made. In the common case of inlining, no module-level mappings are needed, so MapValue doesn't need to examine non-function-local metadata, which can be very expensive in the case of a large module with really deep metadata (e.g. a large C++ program compiled with -g). This flag is a little awkward; perhaps eventually it can be moved into the ClonedCodeInfo class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112190 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Utils/InlineFunction.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'lib/Transforms/Utils/InlineFunction.cpp') diff --git a/lib/Transforms/Utils/InlineFunction.cpp b/lib/Transforms/Utils/InlineFunction.cpp index b7677b5a3c..88979e862d 100644 --- a/lib/Transforms/Utils/InlineFunction.cpp +++ b/lib/Transforms/Utils/InlineFunction.cpp @@ -365,7 +365,8 @@ bool llvm::InlineFunction(CallSite CS, InlineFunctionInfo &IFI) { // have no dead or constant instructions leftover after inlining occurs // (which can happen, e.g., because an argument was constant), but we'll be // happy with whatever the cloner can do. - CloneAndPruneFunctionInto(Caller, CalledFunc, VMap, Returns, ".i", + CloneAndPruneFunctionInto(Caller, CalledFunc, VMap, + /*ModuleLevelChanges=*/false, Returns, ".i", &InlinedFunctionInfo, IFI.TD, TheCall); // Remember the first block that is newly cloned over. -- cgit v1.2.3-18-g5258
