Unfortunately, I didn't follow your instructions precisely, so perhaps
this doesn't count. I used the last snapshot tarball (20010910) instead of
direct from CVS.
Compiled one of the in-house C++ systems from scratch using 3.0.1 and
the snapshot last night:
gcc-3.0.1:
1853.43s user 45.26s system 50% cpu 1:02:46:71 total
gcc-3.0.1.1 [3.0.2 20010910 (prerelease)]:
1849.85s user 44.17s system 50% cpu 1:02:37:50 total
No check for difference in code generation, of course, just compile
times.
