[Q] Optimization for Sun SPARC.

Hi,

I'm about to compile GCC 3.3 on Solaris 2.8.  I thought that it'd be a 
good idea to optimize GCC *itself* to make future compilations faster.

I'm trying to figure out how to get the most optimization possible out of 
GCC.  I was thinking of "-O3 -fmove-all-movables".  Is there anything I 
should add to that?

I know that "-ffast-math" can cause problems with some programs.  Can I 
use "-ffast-math" to compile GCC itself?

Also, I need help figuring out the architacture-specific flag 
"-mcpu=cpu_type".  How do I find out what cpu type my computer has?

Thanks for the help.
