◆ parseDialectSymbolBody() [2/2]

ParseResult Parser::parseDialectSymbolBody	(	StringRef &	body,
		bool &	isCodeCompletion
	)

Parse the body of a dialect symbol, which starts and ends with <>'s, and may be recursive.

pretty-dialect-sym-body ::= '<' pretty-dialect-sym-contents+ '>' pretty-dialect-sym-contents ::= pretty-dialect-sym-body | '(' pretty-dialect-sym-contents+ ')' | '[' pretty-dialect-sym-contents+ ']' | '{' pretty-dialect-sym-contents+ '}' | '[^[<({>])}\0]+'

Return with the 'body' StringRef encompassing the entire body. isCodeCompletion is set to true if the body contained a code completion location, in which case the body is only populated up to the completion.

◆ parseDimensionListRanked()

ParseResult Parser::parseDimensionListRanked	(	SmallVectorImpl< int64_t > &	dimensions,
		bool	allowDynamic = `true`,
		bool	withTrailingX = `true`
	)

Parse a dimension list of a tensor or memref type.

This populates the dimension list, using ShapedType::kDynamic for the ? dimensions if allowDynamic is set and errors out on ? otherwise. Parsing the trailing x is configurable.

dimension-list ::= eps | dimension (x dimension)* dimension-list-with-trailing-x ::= (dimension x)* dimension ::= ? | decimal-literal

When allowDynamic is not set, this is used to parse:

static-dimension-list ::= eps | decimal-literal (x decimal-literal)* static-dimension-list-with-trailing-x ::= (dimension x)*

inline

Reset the parser to the given lexer position.

Resetting the parser/lexer position does not update 'state.lastToken'. 'state.lastToken' is the last parsed token, and is used to provide the scope end location for OperationDefinitions. To ensure the correctness of the end location, the last consumed token of an OperationDefinition needs to be the last token belonging to it.
