The latest gcc-snapshot seems quite a bit better, but still much slower than g++-4.1: frobnitz:/tmp/buildd/python-qt3-3.17.3/build-2.4/qt# time g++-4.1 -c -O2 -pipe -fPIC -g -Wall -W -D_REENTRANT -DQT_THREAD_SUPPORT -I. -I/usr/include/python2.5 -I/usr/share/qt3/mkspecs/default -I/usr/share/qt3/include -I/usr/X11R6/include -o sipqtpart0.o sipqtpart0.cpp real 0m46.583s user 0m43.527s sys 0m1.052s frobnitz:/tmp/buildd/python-qt3-3.17.3/build-2.4/qt# time g++-4.2 -c -O2 -pipe -fPIC -g -Wall -W -D_REENTRANT -DQT_THREAD_SUPPORT -I. -I/usr/include/python2.5 -I/usr/share/qt3/mkspecs/default -I/usr/share/qt3/include -I/usr/X11R6/include -o sipqtpart0.o sipqtpart0.cpp real 58m56.571s user 50m55.711s sys 7m43.485s frobnitz:/tmp/buildd/python-qt3-3.17.3/build-2.4/qt# time /usr/lib/gcc-snapshot/bin/g++ -c -O2 -pipe -fPIC -g -Wall -W -D_REENTRANT -DQT_THREAD_SUPPORT -I. -I/usr/include/python2.5 -I/usr/share/qt3/mkspecs/default -I/usr/share/qt3/include -I/usr/X11R6/include -o sipqtpart0.o sipqtpart0.cpp In file included from /tmp/buildd/python-qt3-3.17.3/sip/qt/qimage.sip:139: /usr/share/qt3/include/qimage.h: In member function 'bool QImageTextKeyLang::operator<(const QImageTextKeyLang&) const': /usr/share/qt3/include/qimage.h:58: warning: suggest parentheses around && within || /tmp/buildd/python-qt3-3.17.3/sip/qt/qtabbar.sip: In function 'PyObject* meth_QTabBar_tabList(PyObject*, PyObject*)': /tmp/buildd/python-qt3-3.17.3/sip/qt/qtabbar.sip:255: warning: suggest explicit braces to avoid ambiguous 'else' real 8m47.002s user 8m37.520s sys 0m2.244s I'll attach the preprocessed source using gcc-snapshot 20070811 in a separate message. -- Daniel Schepler -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
