CanonicalizeFile()

StringRef FileCheck::CanonicalizeFile	(	MemoryBuffer &	MB,
		SmallVectorImpl< char > &	OutputBuffer
	)

Canonicalizes whitespaces in the file.

Line endings are replaced with UNIX-style '
'.

checkInput()

bool FileCheck::checkInput	(	SourceMgr &	SM,
		StringRef	Buffer,
		std::vector< FileCheckDiag > *	Diags = nullptr
	)

Checks the input to FileCheck provided in the Buffer against the expected strings read from the check file and record diagnostics emitted in Diags.

Errors are recorded against SM.

Returns

false if the input fails to satisfy the checks.

readCheckFile()

bool FileCheck::readCheckFile	(	SourceMgr &	SM,
		StringRef	Buffer,
		std::pair< unsigned, unsigned > *	ImpPatBufferIDRange = nullptr
	)

Reads the check file from Buffer and records the expected strings it contains.

Errors are reported against SM.

If ImpPatBufferIDRange, then the range (inclusive start, exclusive end) of IDs for source buffers added to SM for implicit patterns are recorded in it. The range is empty if there are none.
