I've run the SAS 5.10 global optimizer on a 20,000 line (non-comments) C 
program that does graphics, MIDI I/O, hardware timer interrupts, and other
goodies, and the results are just peachy.  I'd call that program non-trivial.

Of course, I did hit the #pragma bug (odd constants passed to system calls with
lots of args will crash the compiler), but once I got beyond that, no problems.
Ever since Lattice introduced the global optimizer, it has produced code that
works the same as without the optimizer, and the code is smaller and presumably
faster (though I haven't really noticed a speed difference in the programs
I've tried).
