Detailed Description

Information for lazily generating a cleanup.

Subclasses must be POD-like: cleanups will not be destructed, and they will be allocated on the cleanup stack and freely copied and moved around.

Cleanup implementations should generally be declared in an anonymous namespace.

Member Function Documentation

◆ Emit()

virtual void clang::CodeGen::EHScopeStack::Cleanup::Emit ( CodeGenFunction CGF,
Flags  flags 
pure virtual

Emit the cleanup.

For normal cleanups, this is run in the same EH context as when the cleanup was pushed, i.e. the immediately-enclosing context of the cleanup scope. For EH cleanups, this is run in a terminate context.

Implemented in clang::CodeGen::CatchRetScope, clang::CodeGen::CodeGenFunction::CallLifetimeEnd, and clang::CodeGen::CodeGenFunction::OMPBuilderCBHelpers::OMPAllocateCleanupTy.
