Hi!Initially I meant to optimize GCC, that includes runtime and memory usage, of course.
Sure. I meant that we have testcases that are good to test your work on. Profile GCC running them and fix the hotspots: this may show quadratic algorithms, and the like.
For example, see the patch and thread at http://permalink.gmane.org/gmane.comp.gcc.patches/137697
I hope this clarifies my earlier message! Paolo
