From 0774cb84719f2aea3016493a2bbd9a02aa3e0541 Mon Sep 17 00:00:00 2001 From: John McCall Date: Sun, 15 May 2011 01:53:33 +0000 Subject: Use arrays and SmallVectors instead of std::vectors when building function types. Also, cache a translation of 'void' in CGM and provide a ptrdiff_t alias. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131373 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CodeGenModule.cpp | 35 ++++++++++++++--------------------- 1 file changed, 14 insertions(+), 21 deletions(-) (limited to 'lib/CodeGen/CodeGenModule.cpp') diff --git a/lib/CodeGen/CodeGenModule.cpp b/lib/CodeGen/CodeGenModule.cpp index eff41c17cd..84fa4af669 100644 --- a/lib/CodeGen/CodeGenModule.cpp +++ b/lib/CodeGen/CodeGenModule.cpp @@ -90,9 +90,10 @@ CodeGenModule::CodeGenModule(ASTContext &C, const CodeGenOptions &CGO, // Initialize the type cache. llvm::LLVMContext &LLVMContext = M.getContext(); - Int8Ty = llvm::Type::getInt8Ty(LLVMContext); - Int32Ty = llvm::Type::getInt32Ty(LLVMContext); - Int64Ty = llvm::Type::getInt64Ty(LLVMContext); + VoidTy = llvm::Type::getVoidTy(LLVMContext); + Int8Ty = llvm::Type::getInt8Ty(LLVMContext); + Int32Ty = llvm::Type::getInt32Ty(LLVMContext); + Int64Ty = llvm::Type::getInt64Ty(LLVMContext); PointerWidthInBits = C.Target.getPointerWidth(0); PointerAlignInBytes = C.toCharUnitsFromBits(C.Target.getPointerAlign(0)).getQuantity(); @@ -342,8 +343,7 @@ void CodeGenModule::AddGlobalDtor(llvm::Function * Dtor, int Priority) { void CodeGenModule::EmitCtorList(const CtorList &Fns, const char *GlobalName) { // Ctor function type is void()*. - llvm::FunctionType* CtorFTy = - llvm::FunctionType::get(llvm::Type::getVoidTy(VMContext), false); + llvm::FunctionType* CtorFTy = llvm::FunctionType::get(VoidTy, false); llvm::Type *CtorPFTy = llvm::PointerType::getUnqual(CtorFTy); // Get the type of a ctor entry, { i32, void ()* }. @@ -856,7 +856,7 @@ CodeGenModule::GetOrCreateLLVMFunction(llvm::StringRef MangledName, if (isa(Ty)) { FTy = cast(Ty); } else { - FTy = llvm::FunctionType::get(llvm::Type::getVoidTy(VMContext), false); + FTy = llvm::FunctionType::get(VoidTy, false); IsIncompleteFunction = true; } @@ -2269,14 +2269,11 @@ llvm::Constant *CodeGenModule::getBlockObjectDispose() { } // Otherwise construct the function by hand. - const llvm::FunctionType *FTy; - std::vector ArgTys; - const llvm::Type *ResultType = llvm::Type::getVoidTy(VMContext); - ArgTys.push_back(Int8PtrTy); - ArgTys.push_back(llvm::Type::getInt32Ty(VMContext)); - FTy = llvm::FunctionType::get(ResultType, ArgTys, false); + const llvm::Type *args[] = { Int8PtrTy, Int32Ty }; + const llvm::FunctionType *fty + = llvm::FunctionType::get(VoidTy, args, false); return BlockObjectDispose = - CreateRuntimeFunction(FTy, "_Block_object_dispose"); + CreateRuntimeFunction(fty, "_Block_object_dispose"); } llvm::Constant *CodeGenModule::getBlockObjectAssign() { @@ -2291,15 +2288,11 @@ llvm::Constant *CodeGenModule::getBlockObjectAssign() { } // Otherwise construct the function by hand. - const llvm::FunctionType *FTy; - std::vector ArgTys; - const llvm::Type *ResultType = llvm::Type::getVoidTy(VMContext); - ArgTys.push_back(Int8PtrTy); - ArgTys.push_back(Int8PtrTy); - ArgTys.push_back(llvm::Type::getInt32Ty(VMContext)); - FTy = llvm::FunctionType::get(ResultType, ArgTys, false); + const llvm::Type *args[] = { Int8PtrTy, Int8PtrTy, Int32Ty }; + const llvm::FunctionType *fty + = llvm::FunctionType::get(VoidTy, args, false); return BlockObjectAssign = - CreateRuntimeFunction(FTy, "_Block_object_assign"); + CreateRuntimeFunction(fty, "_Block_object_assign"); } llvm::Constant *CodeGenModule::getNSConcreteGlobalBlock() { -- cgit v1.2.3-70-g09d2
