After repeatedly failing to compile x11-toolkits/qt{145,22} on
-CURRENT, I've finally come to conclusion that qt can't be compiled
with -O due to black magic of prereleased gcc-2.95.3.
with CXXFLAGS='-O -pipe', it fails at linking bin/moc as follows:
========
c++ -c -DQT_XFT -I/usr/obj/ports/home/k5/work/Z/qt22/work/qt-2.2.3/include -pthread -D_THREAD_SAFE -Wno-unused -Wno-parentheses -DQT_PREFIX=\"/usr/X11R6\" -O -pipe -DQT_NO_CODECS -DQT_LITE_UNICODE -I../../include -I../tools -I. -o qfile_unix.o ../tools/qfile_unix.cpp
c++ -o ./moc2 mocgen.o qbuffer.o qcollection.o qcstring.o qdatastream.o qdatetime.o qfile.o qgarray.o qgdict.o qglist.o qglobal.o qgvector.o qiodevice.o qregexp.o qstring.o qtextcodec.o qtextstream.o qfile_unix.o
qglist.o: In function `QGList::read(QDataStream &)':
qglist.o(.text+0x12b3): undefined reference to `L1341'
gmake[1]: *** [moc2] Error 1
========
but with CXXFLAGS='-O2 -pipe', it seems OK:
========
c++ -c -DQT_XFT -I/usr/obj/ports/home/k5/work/Z/qt22/work/qt-2.2.3/include -pthread -D_THREAD_SAFE -Wno-unused -Wno-parentheses -DQT_PREFIX=\"/usr/X11R6\" -pipe -O2 -DQT_NO_CODECS -DQT_LITE_UNICODE -I../../include -I../tools -I. -o qfile_unix.o ../tools/qfile_unix.cpp
c++ -o ./moc2 mocgen.o qbuffer.o qcollection.o qcstring.o qdatastream.o qdatetime.o qfile.o qgarray.o qgdict.o qglist.o qglobal.o qgvector.o qiodevice.o qregexp.o qstring.o qtextcodec.o qtextstream.o qfile_unix.o
gmake[1]: Leaving directory `/usr/obj/ports/home/k5/work/Z/qt22/work/qt-2.2.3/src/moc'
========
I wrote a cut'n'try script and got this result:
adding -frerun-cse-after-loop to CXXFLAGS is enough.
========
c++ -c -DQT_XFT -I/usr/obj/ports/home/k5/work/Z/qt22/work/qt-2.2.3/include -pthread -D_THREAD_SAFE -Wno-unused -Wno-parentheses -DQT_PREFIX=\"/usr/X11R6\" -O -pipe -frerun-cse-after-loop -DQT_NO_CODECS -DQT_LITE_UNICODE -I../../include -I../tools -I. -o qfile_unix.o ../tools/qfile_unix.cpp
c++ -o ./moc2 mocgen.o qbuffer.o qcollection.o qcstring.o qdatastream.o qdatetime.o qfile.o qgarray.o qgdict.o qglist.o qglobal.o qgvector.o qiodevice.o qregexp.o qstring.o qtextcodec.o qtextstream.o qfile_unix.o
gmake[1]: Leaving directory `/usr/obj/ports/home/k5/work/Z/qt22/work/qt-2.2.3/src/moc'
========
How about adding this workaround?
