GCC-4.5.0 comparison with previous releases and LLVM-2.7 on SPEC2000 for x86/x86_64

[Jan Hubicka]

Hi,
and for size, could you please also do -Os comparsions?  I am aware that -O2
inliner is tuned somewhat up at C++.  This is given by fact that we do have C++
benchmark suite we use to monitor inlining.

Programs there are a lot more aggressive on abstraction than whatever SPEC2k
and SPEC2k6 does.  I know I can tune the inliner down for SPEC but get
regression there... But given we can get 10% difference on normal C++ program
it might be interesting to consider some compromise, at least for -O2.
