From b03527a9a395168762ad8e25e59a7a272dd74561 Mon Sep 17 00:00:00 2001 From: John McCall Date: Wed, 17 Oct 2012 04:53:31 +0000 Subject: Set a special flag in class metadata when an Objective-C class has ivars that require destruction, but none that require anything except zero-initialization. This is common in ARC and (when true throughout a class hierarchy) permits the elimination of an unnecessary message-send during allocation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166088 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CodeGenModule.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/CodeGen/CodeGenModule.cpp') diff --git a/lib/CodeGen/CodeGenModule.cpp b/lib/CodeGen/CodeGenModule.cpp index e9344a1351..95753d540e 100644 --- a/lib/CodeGen/CodeGenModule.cpp +++ b/lib/CodeGen/CodeGenModule.cpp @@ -2541,7 +2541,7 @@ void CodeGenModule::EmitObjCIvarInitializations(ObjCImplementationDecl *D) { /*isDefined=*/false, ObjCMethodDecl::Required); D->addInstanceMethod(DTORMethod); CodeGenFunction(*this).GenerateObjCCtorDtorMethod(D, DTORMethod, false); - D->setHasCXXStructors(true); + D->setHasDestructors(true); } // If the implementation doesn't have any ivar initializers, we don't need @@ -2565,7 +2565,7 @@ void CodeGenModule::EmitObjCIvarInitializations(ObjCImplementationDecl *D) { ObjCMethodDecl::Required); D->addInstanceMethod(CTORMethod); CodeGenFunction(*this).GenerateObjCCtorDtorMethod(D, CTORMethod, true); - D->setHasCXXStructors(true); + D->setHasNonZeroConstructors(true); } /// EmitNamespace - Emit all declarations in a namespace. -- cgit v1.2.3-70-g09d2
