Thanks for the data point.
Don't forget the point that PCH negates it :). If it turns out that PCH on Windows is actually feasible now, I wouldn't consider that a blocker. > PS: what is the perf impact if any on GCC to use the pch include > layout (that is even the pch feature, but over-including headers) > If that overhead is not prohibitive then we could use that way of > doing include _always_... and therefore the pch layout would be > maintained 'naturally'. It about doubles the time for building xmloff (assuming I understood correctly that you meant using PCH include layout without GCC's PCH support activated). -- Lubos Lunak [email protected] _______________________________________________ LibreOffice mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/libreoffice
