Match()

size_t FileCheckPattern::Match	(	StringRef	Buffer,
		size_t &	MatchLen,
		StringMap< StringRef > &	VariableTable
	)		const

Matches the pattern string against the input buffer Buffer.

This returns the position that is matched or npos if there is no match. If there is a match, the size of the matched string is returned in MatchLen.

The VariableTable StringMap provides the current values of filecheck variables and is updated if this match defines new values.

ParsePattern()

bool FileCheckPattern::ParsePattern	(	StringRef	PatternStr,
		StringRef	Prefix,
		SourceMgr &	SM,
		unsigned	LineNumber,
		const FileCheckRequest &	Req
	)

Parses the given string into the Pattern.

Prefix provides which prefix is being matched, SM provides the SourceMgr used for error reports, and LineNumber is the line number in the input file from which the pattern string was read. Returns true in case of an error, false otherwise.
