From 23b4c68f465373f5c82551e42725af5dc150221f Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Wed, 4 Feb 2004 01:19:43 +0000 Subject: Give CloneBasicBlock an optional function argument to specify which function to add the cloned block to. This allows the block to be added to the function immediately, and all of the instructions to be immediately added to the function symbol table, which speeds up the inliner from 3.7 -> 3.38s on the PR209. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11107 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Utils/CloneFunction.cpp | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'lib/Transforms/Utils/CloneFunction.cpp') diff --git a/lib/Transforms/Utils/CloneFunction.cpp b/lib/Transforms/Utils/CloneFunction.cpp index 17ad8c5175..4aa1aaa0d2 100644 --- a/lib/Transforms/Utils/CloneFunction.cpp +++ b/lib/Transforms/Utils/CloneFunction.cpp @@ -42,8 +42,8 @@ static inline void RemapInstruction(Instruction *I, // CloneBasicBlock - See comments in Cloning.h BasicBlock *llvm::CloneBasicBlock(const BasicBlock *BB, std::map &ValueMap, - const char *NameSuffix) { - BasicBlock *NewBB = new BasicBlock(""); + const char *NameSuffix, Function *F) { + BasicBlock *NewBB = new BasicBlock("", F); if (BB->hasName()) NewBB->setName(BB->getName()+NameSuffix); // Loop over all instructions copying them over... @@ -82,8 +82,7 @@ void llvm::CloneFunctionInto(Function *NewFunc, const Function *OldFunc, const BasicBlock &BB = *BI; // Create a new basic block and copy instructions into it! - BasicBlock *CBB = CloneBasicBlock(&BB, ValueMap, NameSuffix); - NewFunc->getBasicBlockList().push_back(CBB); + BasicBlock *CBB = CloneBasicBlock(&BB, ValueMap, NameSuffix, NewFunc); ValueMap[&BB] = CBB; // Add basic block mapping. if (ReturnInst *RI = dyn_cast(CBB->getTerminator())) -- cgit v1.2.3-18-g5258
