(GSO) A function sequence generator that uses an exhaustive generate-and-test approach to find the shortest instruction sequence for a given function. Written by Torbjorn Granlund <firstname.lastname@example.org> and Tom Wood. You have to tell the superoptimiser which function and which CPU you want to get code for. This is useful for compiler writers.
