There were of course complaints and discussions about this, and I even tried to tweak inlining parameters once. See the audit trails of PR7863 and PR8704. There were people telling me "well in branch XYZ we do so much better", as always, so I was not encouraged to persue this further. Anyway, I think we should try the patch on mainline and I'll plan to re-submit it together with a 10% lowering of the inlining parameters compared to 3.4 (this is conservative for the mean size change for C code, for C++ we're still too high). I personally cannot afford to do so much testing to please everyone. Richard.
