Assembly output from JRuby 'fib'

[Charles Oliver Nutter]

Well, that's a good question. We would want it for any operation that could overflow. I do not know about such things...someone more familiar with machine/JVM overflow and checks for it would want to flesh out details.

Perhaps something like Math.isCarry(long operand1, long operand2, long result, MathOperation op) where MathOperation is an enum of operations for which we want to detect overflow. Enums don't present any sort of barrier to intrinsification, do they?
