I'm playing with changes to the support for -fprefetch-loop-arrays on
ia64 and want to see how they affect other architectures, so I obtained
access to a powerpc64-unknown-linux-gnu system.  My first naive attempt
to build the 3.1-20020408 snapshot there failed.  I started over, this
time specifying "--host=powerpc-unknown-linux-gnu" for configure, but
"make bootstrap" failed with an assertion error building libstdc++.
A current bootstrap of only C is making good progress, but I'd like to
be able to test with C++ and Fortran 77.  Should I expect to be able to
build all default languages there?  Are there configuration options I
need to use?  I don't care whether I can have 64-bit binaries or not.

	I am not aware of problem building ppc64 GCC 3.1.  The ppc64 Linux
development team uses it regularly.  Do you have ppc64 binutils and ppc64
glibc installed on the test system?

I don't have access to the system right now, but it probably doesn't have
ppc64 tools.  My first attempt failed with an assembler error so I built
new binutils which were apprently ppc64, and the second attempt failed
because xxx/xxx64/crti.o (can't remember the real name) wasn't found, so
that probably means there was no ppc64 glibc.  Then I rebuilt the new
binutils with host=powerpc-unknown-linux-gnu.  I'll find out Monday if
I can install ppc64 binutils and glibc.  If not, should I be able to
build and use a 32-bit GCC 3.1 on such a system?

Sorry, I should look into this more myself before asking here.

Yes, trying to build --enable-shared without glibc installed is doomed.

Starting off without any tools, the sequence is:

o  Build and install binutils.  Use --disable-shared.  eg. configure
   /src/binutils/configure --prefix=/usr/local \
     --build=powerpc-linux --host=powerpc-linux --target=powerpc64-linux \
     --disable-nls --disable-shared

o  Build and install gcc.  Use --disable-shared --enable-languages=c
   and use exactly the same --prefix, --build, --host and --target as
   you used for binutils.  eg. configure
   /src/gcc/configure --prefix=/usr/local \
     --build=powerpc-linux --host=powerpc-linux --target=powerpc64-linux \
     --disable-nls --disable-shared --enable-languages=c

o  Build and install glibc.  If you're building cross-tools, then use
   --prefix=$prefix/$target, where $prefix and $target are the values
   used for --prefix and --target respectively when compiling binutils.
   For native targets, use the same --prefix as binutils.  eg. configure
   /src/glibc/configure --prefix=/usr/local/powerpc64-linux \
     --build=powerpc-linux --host=powerpc64-linux --target=powerpc64-linux \
     --with-headers=/src/linux-2.4.18-ppc/include --without-cvs \
     --enable-add-ons --disable-profile --enable-shared \
     --disable-sanity-checks

o  Rebuild gcc with --enable-shared --enable-languages=<as_you_like>

You'll note in the above, I've treated powerpc64-linux as a cross-target
from powerpc-linux, even though they might be running on the same machine.
There are a few tool and glibc issues yet to be ironed out...
