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 --- include/llvm/Transforms/Utils/ValueMapper.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'include/llvm/Transforms/Utils/ValueMapper.h') diff --git a/include/llvm/Transforms/Utils/ValueMapper.h b/include/llvm/Transforms/Utils/ValueMapper.h index b219e8e..5274112 100644 --- a/include/llvm/Transforms/Utils/ValueMapper.h +++ b/include/llvm/Transforms/Utils/ValueMapper.h @@ -22,8 +22,10 @@ namespace llvm { class Instruction; typedef ValueMap ValueToValueMapTy; - Value *MapValue(const Value *V, ValueToValueMapTy &VM); - void RemapInstruction(Instruction *I, ValueToValueMapTy &VM); + Value *MapValue(const Value *V, ValueToValueMapTy &VM, + bool ModuleLevelChanges); + void RemapInstruction(Instruction *I, ValueToValueMapTy &VM, + bool ModuleLevelChanges); } // End llvm namespace #endif -- cgit v1.1
