I don't distribute the builds. I only build the C and gfortran compilers, because I'm actively contributing to gfortran. g77 has been removed from GCC. Bootstrapping C and gfortran takes 2 to 3 hours on my 1.2 GHz athlon with 1.5 GB memory and SCSI disks. I've never built g++ or java, but I'm willing to bet that it takes a long, long time. > > >For those that do not know, the entire middle-end and much > >of the back-end of GCC has been re-written in 3.5. > > This is interesting.

To learn more about tree-ssa, which is the guts of 3.5, see http://gcc.gnu.org/projects/tree-ssa/ It's my understanding that once tree-ssa settles down, it will offer many more opportunities for high level optimizations. -- Steve
