Hi!

I successfully compiled and installed egcs 1.0 on a RedHat 5.0 system.

The hardware is a Dual PPro 166 w. 128 Megs. I guess compile took around
half an hour (although I didn't time it).


I did a little timing on a molecular dynamics simulation tool, comparing
the performance when compiled with standard GCC and with EGCS.

Options used with GCC:
-m486 -O3 -fexpensive-optimizations -fomit-frame-pointer

Options used with EGCS:
-march=3Di686 -O3 -fexpensive-optimizations -fomit-frame-pointer

I experienced no real speedup, but that was expected since the program is
very memory intensive, so I guess most of the time in the program is spent
waiting on cache-misses. Especially because the program runs on both CPUs.
That really gives the crappy PC memory subsystem something to work with!

Regrettably I do not have time to test egcs on more CPU intensive programs
for the time being.


Virtual beer to the Egcs people!  We sure needed a GCC with a pentium
optimizer.
