class CodeGenFunction::RunCleanupsScope

Declaration

class CodeGenFunction::RunCleanupsScope { /* full declaration omitted */ };

Description

Enters a new scope for capturing cleanups, all of which will be executed once the scope is exited.

Method Overview

• public void ForceCleanup(std::initializer_list<llvm::Value **> ValuesToReload = {})
• private RunCleanupsScope(const clang::CodeGen::CodeGenFunction::RunCleanupsScope &)
• public RunCleanupsScope(clang::CodeGen::CodeGenFunction & CGF)
• public bool requiresCleanups() const
• public ~RunCleanupsScope()

Methods

¶void ForceCleanup(
    std::initializer_list<llvm::Value**>
        ValuesToReload = {})

Description

Force the emission of cleanups now, instead of waiting until this object is destroyed.

Declared at: clang/lib/CodeGen/CodeGenFunction.h:917

Parameters

std::initializer_list<llvm::Value**> ValuesToReload = {}

- A list of values that need to be available at the insertion point after cleanup emission. If cleanup emission created a shared cleanup block, these value pointers will be rewritten. Otherwise, they not will be modified.

¶RunCleanupsScope(
    const clang::CodeGen::CodeGenFunction::
        RunCleanupsScope&)

Declared at: clang/lib/CodeGen/CodeGenFunction.h:880

Parameters

const clang::CodeGen::CodeGenFunction:: RunCleanupsScope&

¶RunCleanupsScope(
    clang::CodeGen::CodeGenFunction& CGF)

Description

Enter a new cleanup scope.

Declared at: clang/lib/CodeGen/CodeGenFunction.h:888

Parameters

clang::CodeGen::CodeGenFunction& CGF

¶bool requiresCleanups() const

Description

Determine whether this scope requires any cleanups.

Declared at: clang/lib/CodeGen/CodeGenFunction.h:907

¶~RunCleanupsScope()

Description

Exit this cleanup scope, emitting any accumulated cleanups.
