Member Function Documentation

std::error_code InstrProfWriter::addFunctionCounts	(	StringRef	FunctionName,
		uint64_t	FunctionHash,
		ArrayRef< uint64_t >	Counters
	)

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.
