		ExtensionDirectiveHandler	Handler
	)

pure virtual

virtual void llvm::MCAsmParser::checkForValidSection ( )

pure virtual

checkForValidSection - Ensure that we have a valid section set in the streamer. Otherwise, report an error and switch to .text.

virtual void llvm::MCAsmParser::eatToEndOfStatement ( )

pure virtual

eatToEndOfStatement - Skip to the end of the current statement, for error recovery.

virtual bool llvm::MCAsmParser::Error	(	SMLoc	L,
		const Twine &	Msg,
		ArrayRef< SMRange >	Ranges = `None`
	)

pure virtual

Error - Emit an error at the location L, with the message Msg.

Returns: The return value is always true, as an idiomatic convenience to clients.

virtual bool llvm::MCAsmParser::parseAbsoluteExpression ( int64_t & Res )

pure virtual

parseAbsoluteExpression - Parse an expression which must evaluate to an absolute value.

Parameters

Res	- The value of the absolute expression. The result is undefined on error.

Returns: - False on success.

virtual bool llvm::MCAsmParser::parseEscapedString ( std::string & Data )

pure virtual

parseEscapedString - Parse the current token as a string which may include escaped characters and return the string contents.

pure virtual

parseExpression - Parse an arbitrary expression.

Parameters

pure virtual

parsePrimaryExpr - Parse a primary expression.

Parameters

Res	- The value of the expression. The result is undefined on error.

Returns: - False on success.

virtual StringRef llvm::MCAsmParser::parseStringToEndOfStatement ( )

pure virtual

Parse up to the end of statement and return the contents from the current token until the end of the statement; the current token on exit will be either the EndOfStatement or EOF.
