> ps: gcc has a very large number of passes over its trees, at least when optimizing.

according to the documentation, there
are around 100 SSA form optimization passes and 70 RTL optimization passes
-O2 and -O3 are noticably slower than -O0.
  (and -enable-checking=all is much slower again, and we do still have problems there..)

Bing for "gcc internal passes" and you should find it.
