virtual TranslationUnitKind getTranslationUnitKind ()
For AST-based actions, the kind of translation unit we're handling.
virtual bool hasPCHSupport () const
Does this action support use with PCH?
virtual bool hasASTFileSupport () const
Does this action support use with AST files?
virtual bool hasIRSupport () const
Does this action support use with IR files?
virtual bool hasCodeCompletionSupport () const
Does this action support use with code completion?
bool PrepareToExecute (CompilerInstance &CI)
Prepare the action to execute on the given compiler instance.
bool BeginSourceFile (CompilerInstance &CI, const FrontendInputFile &Input)
Prepare the action for processing the input file Input.
llvm::Error Execute ()
Set the source manager's main input file, and run the action.
virtual void EndSourceFile ()
Perform any per-file post processing, deallocate per-file objects, and run statistics and output file cleanup code.
Protected Member Functions
std::unique_ptr< ASTConsumer > CreateASTConsumer (CompilerInstance &CI, StringRef InFile) override
Provide a default implementation which returns aborts; this method should never be called by FrontendAction clients.

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 BeginSourceFileAction (CompilerInstance &CI)
Callback at the start of processing a single input.
virtual void ExecuteAction ()=0
Callback to run the program action, using the initialized compiler instance.
virtual void EndSourceFileAction ()
Callback at the end of processing a single input.
virtual bool shouldEraseOutputFiles ()
Callback at the end of processing a single input, to determine if the output files should be erased or not.

◆ CreateASTConsumer()

std::unique_ptr< ASTConsumer > PreprocessorFrontendAction::CreateASTConsumer ( CompilerInstance & CI, StringRef InFile ) overrideprotectedvirtual

◆ usesPreprocessorOnly()

bool clang::PreprocessorFrontendAction::usesPreprocessorOnly ( ) const inlineoverridevirtual

Does this action only use the preprocessor?

If so no AST context will be created and this action will be invalid with AST file inputs.

Implements clang::FrontendAction.
