All benchmarks were done in a pentium 200 with 64MB RAM and NT 4.0. This impressed me for several reasons. Given that the team for all the system in lcc-win32 is only three people, this is a reason to be proud of. Nothing executes faster than a deleted instruction.
Smaller code fits better in the cache, and reduces main memory access.
In the future and if time permits, I will try to improve it by adding CSE and loop peephole register allocation.
