Detailed Description

Constructor & Destructor Documentation

◆ CodeGenAction()

CodeGenAction::CodeGenAction ( unsigned  _Act,
llvm::LLVMContext *  _VMContext = nullptr 
)
protected

Create a new code generation action.

If the optional _VMContext parameter is supplied, the action uses it without taking ownership, otherwise it creates a fresh LLVM context and takes ownership.

Definition at line 796 of file CodeGenAction.cpp.

◆ ~CodeGenAction()

CodeGenAction::~CodeGenAction ( )
override

Definition at line 800 of file CodeGenAction.cpp.

Member Function Documentation

◆ CreateASTConsumer()

StringRef  InFile 
)
overrideprotectedvirtual

◆ EndSourceFileAction()

void CodeGenAction::EndSourceFileAction ( )
overrideprotectedvirtual

Callback at the end of processing a single input.

This is guaranteed to only be called following a successful call to BeginSourceFileAction (and BeginSourceFile).

Reimplemented from clang::FrontendAction.

Definition at line 808 of file CodeGenAction.cpp.

◆ ExecuteAction()

void CodeGenAction::ExecuteAction ( )
overrideprotectedvirtual

◆ hasIRSupport()

bool CodeGenAction::hasIRSupport ( ) const
overrideprotectedvirtual

Does this action support use with IR files?

Reimplemented from clang::FrontendAction.

Definition at line 806 of file CodeGenAction.cpp.

◆ takeLLVMContext()

llvm::LLVMContext * CodeGenAction::takeLLVMContext ( )

Take the LLVM context used by this action.

Definition at line 821 of file CodeGenAction.cpp.

◆ takeModule()

std::unique_ptr< llvm::Module > CodeGenAction::takeModule ( )

Take the generated LLVM module, for use after the action has been run.

The result may be null on failure.
