(0) Restore DevTools to its original state
$ su
# rpm -e gcc2-with-g77
# rpm -e gcc-with-g77-symlinks
# rpm -e gcc-with-g77
# pushd <somewhere>
# rpm -ivh gcc-orig-1151-1a.ppc.rpm gcc-orig-symlinks-1151-1a.ppc.rpm
# rpm -ivh gcc2-orig-7-1a.ppc.rpm


(1) Decide the cvs-tag that corresponds to the distributed gcc3

$ mkdir tmp
$ cd tmp
$ cp /Volumes/December\ 2002\ Dev\ Tools/Packages/DevTools.pkg/Contents/Archive.pax.gz .
$ gunzip Archive.pax.gz 
$ pax -r -pe -f Archive.pax
$ usr/bin/gcc3 --version
gcc3 (GCC) 3.1 20020420 (prerelease)
Copyright (C) 2002 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
$ strings usr/bin/gcc3 | less
....
3.1 20020420 (prerelease)
1175
...

The tag should be gcc3-1175, which is in fearless-kitty-branch.
The version number can be confirmed by examining gcc/version.c.


(2) Install Dec2002 DevTools


(3) Backup original gcc2 and gcc3

$ su
# cd /usr/local/src/apple/SPECS
# rpm -qpl ../RPMS/ppc/gcc2-orig-7-1a.ppc.rpm > list.gcc2
# cat backup.sh
#!/bin/sh
list=$1
mkdir -p usr/{bin,include,lib,libexec}
mkdir -p usr/share/man/man1
for i in `cat $list`; do
   to=`echo $i | sed -e 's;^/;;'`
   if [ -d $i -a ! -h $i ]; then
      mkdir -p $to
   else
      cp -RPp $i $to
   fi
done
exit 0
# sh backup.sh list.gcc2
# tar -zcvf /usr/local/src/apple/SOURCES/gcc2-orig-7-1b-bin.tar.gz usr
# rm -rf usr
# rpmbuild -ba gcc2-orig.spec

# tar -ztvf gcc-with-g77-1175-1a-bin.tar.gz | cut -c49- | sed -e 's;^;/;' | sed -e 's; -> .*;;' | sort > list.gcc3
# sh backup.sh list.gcc3
# tar -zcvf /usr/local/src/apple/SOURCES/gcc-orig-1175-1a-bin.tar.gz usr
# rm -rf usr
# rpmbuild -ba gcc-orig.spec



(4) Get source tree from CVS

$ export CVSROOT=:pserver:fujiik@anoncvs.opensource.apple.com:/cvs/Darwin
$ cvs login
(Logging in to fujiik@anoncvs.opensource.apple.com)
CVS password: ??????
$ cd <somewhere>
$ mkdir gcc3.1-dec2002
$ cd gcc3.1-dec2002
$ cvs -z3 checkout -r gcc3-1175 gcc3
$ mv gcc3 gcc3-1175
$ tar -zcvf gcc3-1175.tar.gz gcc3-1175


(5) Build gcc3
