To cut down compilation times (bootstrapping the Ada and C front ends
currently requires well over three hours over here), I think I've got
to acquire a new piece of hardware. Ordinary benchmarks from credible
parties are usually run on Microsoft Windows, and involve software
compiled by dozens of compilers, but not GCC.
So my question: Which of the two available x86 implementations should
I choose, in order to minimize bootstrapping time? FPU performance
and so on does not matter.
Price vs. performance is probably not so much an issue. However,
non-x86 architectures are a bit too expensive. :-/

You can find a lot of kernel compile time information on Athlon vs
Pentium, eg:
<http://www.linuxhardware.org/features/01/07/13/145249.shtml>
IIRC in most tests I've seen, Athlon is better at compiling the kernel
and cheaper as well.
For reference, on my P3 1GHz laptop, i686-pc-linux-gnu bootstrap for
"c,ada" takes 45 minutes, "ada,c,c++,f77" takes 1 hour,
gnatlib_and_tools is an additional 5 minutes. For "c,c++,f77", make
check is 45 minutes, and ACATS is 35 minutes.
Hope this helps,

For the record, on P3 1GHz, bootstraping "c" takes 25 minutes, as does
make check.

After looking at the test results for Athlon XP processors and some
personal tests on a Dual 1 GHz Pentium III box (slightly under 40
minutes for Ada + C + GNAT tools), I decided to buy an Athlon-based
System (with 1.6 GHz clock speed), which compiles the C and Ada front
ends and the Ada library and tools in about 25 minutes, which is quite
impressive compared to over three long hours on my old system. :-)
(BTW: I'm typing this on the new system, please forgive any errors in
the mail setup.)
