/zlib/inftrees.c:291: Internal compiler error in wrap_constant, atsimplify-rtx.c:2523

[Gerald Pfeifer]

With current CVS sources I'm seeing the following in i386-unknown-freebsd4.2:

/bin/sh ./libtool --mode=compile /files/pfeifer/OBJ/gcc/xgcc -B/files/pfeifer/OBJ/gcc/ -B/sw/test/gcc/FreeBSD/i386-unknown-freebsd4.2/bin/ -B/sw/test/gcc/FreeBSD/i386-unknown-freebsd4.2/lib/ -isystem /sw/test/gcc/FreeBSD/i386-unknown-freebsd4.2/include -DPACKAGE=\"zlib\" -DVERSION=\"1.1.3\" -DHAVE_UNISTD_H=1 -DHAVE_GETPAGESIZE=1 -DHAVE_MEMCPY=1 -DHAVE_STRERROR=1 -DHAVE_UNISTD_H=1  -I. -I/sw/test/gcc/gcc/zlib      -g -O2 -c /sw/test/gcc/gcc/zlib/inftrees.c

Bernd, this *seems* (but not necessarily *is*) to be related to the
following change?

  2000-11-27  Bernd Schmidt  <bernds@redhat.co.uk>

        * haifa-sched.c (print_pattern): Prettier output for COND_EXEC.

        * reload1.c (reload_cse_simplify_set): Pass down mode to cselib_lookup.
        (reload_cse_simplify_operands): Do nothing about operands where both
        the operand and the match_operand fail to give us a mode.
        * simplify-rtx.c (wrap_constant): New function.
                          ^^^^^^^^^^^^^
