A similar error occurs on hppa-linux near the end of stage2:
<http://gcc.gnu.org/ml/gcc/2002-07/msg01238.html>.

Looks promising.  Bootstrap is now into stage3.

Note that he _did_ say stage2 failure.  Thus stage1 was
miscompiled somewhere.

Surprising, to say the least, since I can only imagine problems
_without_ that patch, as evidenced by the SH problems it fixed.

If this is a stage2 failure, can you help me out by finding what
bit of stage1 got miscompiled?

The following patch appears to be the origin of the bootstrap failure
under hppa-linux:

2002-07-25  Richard Henderson  <rth@redhat.com>

	* emit-rtl.c (set_mem_attributes): Fix size and alignment thinkos
	in ARRAY_REF of DECL_P case.

The lines that appeared to be causing the issue used '==', which
is impossible to overflow.  So I've got no idea what's going on
there.

Just for the record, I get the same on ia64-suse-linux.

Well, obviously something in or used by cpplib gets miscompiled.

Do my two libcall related patches from yesterday make any difference
on this?

No, it is 64 on that platform. This also happens on sparc-*-linux-gnu
where it is 32.

You suddenly have a HOST_BITS_PER_WIDE_INT > 64?
(Note, not equal to 64, it's a strict greater than test).

If this is correct, you really do need to fill out the table.
Otherwise, your bug lies elsewhere.
