CONFIG_SHELL as prescribed in the documentation? Do you use GNU make?

------- Additional Comments From ebotcazou at gcc dot gnu dot org  2003-06-26 11:29 -------
This is pretty weird, since TARGET_CPU_DEFAULT is correctly defined in your
config.h file and the line number pointed to by the error message seems to
indicate that the right config.h file is picked up.

I think that, if the problem were in the header files themselves, it would have
been flagged at the beginning of stage1 by the bootstrap compiler, not at the
end by the stage1 compiler. This leads to the conclusion that the stage1
compiler is miscompiled by the bootstrap compiler.

Can you try to bootstrap with another compiler than GCC 3.0.3?

I could try building gcc without optimization. How?

Unfortunately, unless you set CFLAGS when bootstrapping, the bootstrap compiler
is already invoked with no optimization (-g). Nevertheless, GCC performs some
optimizations at -g like constants folding, which are known to have bugs.

I'd suggest to try to bootstrap GCC 3.2.3 as an intermediate stage.

Thanks for the quick feedback. This confirm that GCC 3.0.3 is not able to
bootstrap GCC 3.3 on SPARC/Solaris.

I'd suggest to keep GCC 3.2.3 around for a while because I think it is currently
the most stable GCC 3.x release on SPARC/Solaris.

I just ran into the same problem, bootstrapping 3.3 using 3.0.2.  It also fails
with the same error when 2.95.2 is used to bootstrap.

Comment #6 strikes me as odd; I would not have expected constant folding to touch
the preprocessor.

I just installed a precompiled package of 3.3, and used it to bootstrap 3.3
from source.  It failed with the same error.  This is making less and less
sense to me the more information I gather.

The 3.3 codebase probably triggers a bug deeply rooted in the constant folder
(maybe the one I tried to fix on mainline). It would be nice to extract a
testcase. But GCC 3.2.3 appears to be able to bootstrap GCC 3.3.

I finally got a successful bootstrap, after installing an old native Sun

No wonder this triplet never gets tested.  :-(

Are you sure that you properly re-configured? Because GCC 3.3 is able to
bootstrap the current 3.3 branch on the Solaris box I use.
