Sorry for the inconvenience. I'm looking into it. But any help
that you can provide would be very much appreciated. For example,
a preprocessed source file (privately?) or what the value of mode
is in the failing trunc_int_for_mode or a stack trace.
I've compiled a cross compiler to ia64-suse-linux, which built without
a problem and all my small testcases for mempcpy and stpcpy appear to
be working fine with the cc1. Hence a gengtype-yacc.i would really help
the process. I'm having difficulty getting the include paths right
from a cross-compiler tree.
In the meantime, "-fno-builtin-mempcpy -fno-builtin-stpcpy" should
act as a workaround, should you need to bootstrap the compiler.
Sorry I can't provide an immediate fix. From my understanding of it
the code looks good and is an improvement on what was there before.
I'll try my best to reproduce this on ia64-hp-hpux11.22, but the
very different handling of Pmode vs. ptr_mode on HPUX may mask the
problem.
For the record the patch was originally posted here:
http://gcc.gnu.org/ml/gcc-patches/2003-05/msg00377.html
and approved by Zack via private e-mail (with a small modification).
It was retested with a full bootstrap and full regression testing on
i686-pc-linux-gnu just yesterday with no new failures on that target.
My apologies one again.
Roger

FYI, I receive the same error on PowerPC in the testsuite,
although the compiler does bootstrap. If not for the G++ bootstrap
failure, you would have received this feedback much earlier.

Many thanks. I now understand the cause of the failure and am
currently attempting to bootstrap and regression test the following
patch.
The issue is that in the second hunk, len_rtx is a constant integer
that wasn't handled by the first hunk. We'd then end up calling
simplify_gen_binary(MINUS, VOIDmode, const_int, const_int) which
isn't able to do the constant folding itself. I'll look into a
follow-up patch to see if simplify_gen_binary can be improved to
handle this case. For the time being, the following patch should
fix the powerpc regressions, and probably also the ia64 bootstrap
failure.
Ok to commit to mainline if bootstrapping and regression testing
complete? Once again my sincere apologies.
