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.

Callback at the end of processing a single input, to determine if the output files should be erased or not.

Frontend action adaptor that merges ASTs together.

This action takes an existing AST file and "merges" it into the AST context, producing a merged context. This action is an action adaptor, which forwards most of its calls to another action that will consume the merged context.

ASTMergeAction::ASTMergeAction ( std::unique_ptr< FrontendAction > AdaptedAction,
ArrayRef< std::string > ASTFiles
)

◆ ~ASTMergeAction()

ASTMergeAction::~ASTMergeAction ( ) 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.

Definition at line 20 of file ASTMerge.cpp.

◆ EndSourceFileAction()

void ASTMergeAction::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 83 of file ASTMerge.cpp.

◆ ExecuteAction()

void ASTMergeAction::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.

Definition at line 33 of file ASTMerge.cpp.

◆ hasPCHSupport()

bool ASTMergeAction::hasPCHSupport ( ) const overridevirtual

◆ usesPreprocessorOnly()

bool ASTMergeAction::usesPreprocessorOnly ( ) const overridevirtual

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.
