From c0bf462cf35fe050bddbd8bff967298e4a67e79d Mon Sep 17 00:00:00 2001 From: John McCall Date: Tue, 23 Feb 2010 00:48:20 +0000 Subject: Perform two more constructor/destructor code-size optimizations: 1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96842 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CodeGenModule.cpp | 22 +--------------------- 1 file changed, 1 insertion(+), 21 deletions(-) (limited to 'lib/CodeGen/CodeGenModule.cpp') diff --git a/lib/CodeGen/CodeGenModule.cpp b/lib/CodeGen/CodeGenModule.cpp index 41575e41e5..f819382a93 100644 --- a/lib/CodeGen/CodeGenModule.cpp +++ b/lib/CodeGen/CodeGenModule.cpp @@ -1195,28 +1195,8 @@ static void ReplaceUsesOfNonProtoTypeWithRealFunction(llvm::GlobalValue *Old, void CodeGenModule::EmitGlobalFunctionDefinition(GlobalDecl GD) { - const llvm::FunctionType *Ty; const FunctionDecl *D = cast(GD.getDecl()); - - if (const CXXMethodDecl *MD = dyn_cast(D)) { - bool isVariadic = D->getType()->getAs()->isVariadic(); - - Ty = getTypes().GetFunctionType(getTypes().getFunctionInfo(MD), isVariadic); - } else { - Ty = cast(getTypes().ConvertType(D->getType())); - - // As a special case, make sure that definitions of K&R function - // "type foo()" aren't declared as varargs (which forces the backend - // to do unnecessary work). - if (D->getType()->isFunctionNoProtoType()) { - assert(Ty->isVarArg() && "Didn't lower type as expected"); - // Due to stret, the lowered function could have arguments. - // Just create the same type as was lowered by ConvertType - // but strip off the varargs bit. - std::vector Args(Ty->param_begin(), Ty->param_end()); - Ty = llvm::FunctionType::get(Ty->getReturnType(), Args, false); - } - } + const llvm::FunctionType *Ty = getTypes().GetFunctionType(GD); // Get or create the prototype for the function. llvm::Constant *Entry = GetAddrOfFunction(GD, Ty); -- cgit v1.2.3-70-g09d2
