Help for building 4.5.0 with Graphite

[Davies, Daniel]

I'm trying to build gcc/g++ 4.5.0 with the Graphite optimizations for
i686-pc-solaris2.10.  I'd like to see whether I'm building all this in
the way it should be built, at least at a high level.

http://gcc.gnu.org/install/prerequisites.html says I need PPL and
CLooG-PPL to get Graphite.

http://www.cs.unipr.it/ppl/Download/ftp/releases/LATEST/README.configure
says, "Let us take the occasion to stress, once again, the fact that you
must use exactly the same C++ compiler to compile the C++ interface of
GMP, the PPL and your application, if it uses the C++ interface of the
PPL."  Since "my application" is gcc-4.5.0 and the three stage bootstrap
build of gcc-4.5.0 uses gcc-4.5.0, I'm interpreting this to mean that
GMP, PPL and CLooG must also be built with gcc-4.5.0.

Here are the high level steps I'm using.

1. Build GCC/G++ 4.5.0 incorporating binutils-20.2, gmp-4.3.2,
mpfr-2.4.2 and mpc-0.8.2.  Do not include ppl-0.10.2 or CLooG-PPL-0.15.9
yet.

2. Run the test suite.  I haven't posted the results, but the summaries
are
                === gcc Summary ===

# of expected passes            70567
# of unexpected failures        19
# of expected failures          169
# of unsupported tests          687
/tool/gcc/4.5.0/build/gcc/xgcc  version 4.5.0 (GCC) 

                === g++ Summary ===

# of expected passes            22661
# of unexpected failures        1
# of unexpected successes       1
# of expected failures          152
# of unsupported tests          162
/tool/gcc/4.5.0/build/gcc/testsuite/g++/../../g++  version 4.5.0 (GCC)

3. Use gcc/g++ 4.5.0 to compile GMP again.  This is necessary to set
CPPFLAGS=-fexceptions, to configure it with --enable-cxx and to make
sure the GMP libraries are exported where PPL can see them.

4. Use gcc/g++ 4.5.0 and the new "external" version of GMP (i.e. not the
one that was included in the original gcc build) to build PPL.

5. Use gcc/g++ 4.5.0 and the new GMP and the new PPL to build CLooG

6. Use gcc/g++ 4.5.0, the new GMP, the new PPL and the new CLooG to
rebuild gcc/g++ 4.5.0.  This time, remove the symbolic link to gmp since
we're supplying an pre-built version of gmp.

I'm getting "make check" failures in step 3 and fatal compiler errors in
step 4, so I must not be building this in the same way it was built for
test purposes.  Before I go over the details again, is the general
procedure correct?

Thanks very much for any help,

Dan
