emitError() [1/2]

Token mlir::pdll::Lexer::emitError	(	const char *	loc,
		const Twine &	msg
	)

emitError() [2/2]

Token Lexer::emitError	(	SMRange	loc,
		const Twine &	msg
	)

Emit an error to the lexer with the given location and message.

emitErrorAndNote()

Token Lexer::emitErrorAndNote	(	SMRange	loc,
		const Twine &	msg,
		SMRange	noteLoc,
		const Twine &	note

getDiagEngine()

ast::DiagnosticEngine& mlir::pdll::Lexer::getDiagEngine ( )

inline

Return a reference to the diagnostic engine used by the lexer.

Definition at line 177 of file Lexer.h.

getSourceMgr()

llvm::SourceMgr& mlir::pdll::Lexer::getSourceMgr ( )

inline

Return a reference to the source manager used by the lexer.

Definition at line 174 of file Lexer.h.

lexToken()

Token mlir::pdll::Lexer::lexToken

(

)

Lex the next token and return it.

pushInclude()

LogicalResult Lexer::pushInclude	(	StringRef	filename,
		SMRange	includeLoc
	)

Push an include of the given file.

This will cause the lexer to start processing the provided file. Returns failure if the file could not be opened, success otherwise.

Definition at line 108 of file Lexer.cpp.

References mlir::failure(), and mlir::success().

resetPointer()

void mlir::pdll::Lexer::resetPointer ( const char *  newPointer )

inline

Change the position of the lexer cursor.

The next token we lex will start at the designated point in the input.
