From ffb945ffb5d29b80fd93649c3572b6d87abce3fc Mon Sep 17 00:00:00 2001 From: Anders Carlsson Date: Sat, 14 May 2011 23:26:09 +0000 Subject: When emitting the destructor for a class with a vtable, if we can determine that the destructor body is trivial and that all member variables also have either trivial destructors or trivial destructor bodies, we don't need to initialize the vtable pointers since no virtual member functions will be called on the destructor. Fixes PR9181. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131368 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CGCXX.cpp | 13 +------------ 1 file changed, 1 insertion(+), 12 deletions(-) (limited to 'lib/CodeGen/CGCXX.cpp') diff --git a/lib/CodeGen/CGCXX.cpp b/lib/CodeGen/CGCXX.cpp index 4390f3a3e3..f6fc202eaa 100644 --- a/lib/CodeGen/CGCXX.cpp +++ b/lib/CodeGen/CGCXX.cpp @@ -28,17 +28,6 @@ using namespace clang; using namespace CodeGen; -/// Determines whether the given function has a trivial body that does -/// not require any specific codegen. -static bool HasTrivialBody(const FunctionDecl *FD) { - Stmt *S = FD->getBody(); - if (!S) - return true; - if (isa(S) && cast(S)->body_empty()) - return true; - return false; -} - /// Try to emit a base destructor as an alias to its primary /// base-class destructor. bool CodeGenModule::TryEmitBaseDestructorAsAlias(const CXXDestructorDecl *D) { @@ -47,7 +36,7 @@ bool CodeGenModule::TryEmitBaseDestructorAsAlias(const CXXDestructorDecl *D) { // If the destructor doesn't have a trivial body, we have to emit it // separately. - if (!HasTrivialBody(D)) + if (!D->hasTrivialBody()) return true; const CXXRecordDecl *Class = D->getParent(); -- cgit v1.2.3-70-g09d2
