Member Function Documentation

addRecord() [1/2]

void InstrProfWriter::addRecord	(	NamedInstrProfRecord &&	I,
		uint64_t	Weight,
		function_ref< void(Error)>	Warn
	)

Add function counts for the given function.

If there are already counts for this function and the hash and number of counts match, each counter is summed. Optionally scale counts by Weight.
