◆ mergeThreadCountUpperBound()

void mergeThreadCountUpperBound	(	int32_t &	UpperBound,
		int32_t	Val )

static

Merge the thread count upper bound Val into UpperBound.

UpperBound is -1 while no thread limiting clause has been seen, 0 once one has been seen whose value is not known at compile time, and otherwise the smallest constant bound found so far.

Thread limiting clauses compose by taking the minimum, so a constant bound stays valid whatever the clauses that are not compile time constants evaluate to. That makes it correct to replace the 0 marker with Val, and necessary to keep a clause from raising a smaller bound found earlier.
