Protected Member Functions
bool BeginSourceFileAction (CompilerInstance &CI) override
Callback at the start of processing a single input.
CodeGenAction (unsigned _Act, llvm::LLVMContext *_VMContext=nullptr)
Create a new code generation action.
bool hasIRSupport () const override
Does this action support use with IR files?
std::unique_ptr< ASTConsumer > CreateASTConsumer (CompilerInstance &CI, StringRef InFile) override
Create the AST consumer object for this action, if supported.
void ExecuteAction () override
Callback to run the program action, using the initialized compiler instance.

Callback at the end of processing a single input.
- Protected Member Functions inherited from clang::ASTFrontendAction
void ExecuteAction () override

virtual bool PrepareToExecuteAction (CompilerInstance &CI)
Prepare to execute the action on the given CompilerInstance.
virtual bool BeginInvocation (CompilerInstance &CI)
Callback before starting processing a single input, giving the opportunity to modify the CompilerInvocation or do some other action before BeginSourceFileAction is called.
virtual bool shouldEraseOutputFiles ()
Callback at the end of processing a single input, to determine if the output files should be erased or not.

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 866 of file CodeGenAction.cpp.

◆ ~CodeGenAction()

CodeGenAction::~CodeGenAction ( ) override

◆ BeginSourceFileAction()

◆ CreateASTConsumer()

Create the AST consumer object for this action, if supported.

This routine is called as part of BeginSourceFile(), which will fail if the AST consumer cannot be created. This will not be called if the action has indicated that it only uses the preprocessor.

Parameters

Returns

The new AST consumer, or null on failure.

Implements clang::FrontendAction.

◆ EndSourceFileAction()

void CodeGenAction::EndSourceFileAction ( ) overrideprotectedvirtual

◆ ExecuteAction()

void CodeGenAction::ExecuteAction ( ) overrideprotectedvirtual

Callback to run the program action, using the initialized compiler instance.

This is guaranteed to only be called between BeginSourceFileAction() and EndSourceFileAction().

Implements clang::FrontendAction.
