A regression hunt using an m68k-elf cross compiler on powerpc-linux shows
that the test failure begins with this patch:

* Makefile.in (loop-unroll.o): Add HASHTAB_H and RECOG_H dependency.
* basic-block.h (struct reorder_block_def): Add copy_number field.
* cfgloop.h (biv_p): Declare.
* cfgloopmanip.c (duplicate_loop_to_header_edge): Set copy_number.
* common.opt (fsplit-ivs-in-unroller): New flag.

Both still fail for me

Target: m68k-elf
Configured with: ../gcc/configure --prefix=/home/paul/arm --target=m68k-elf
--with-newlib --disable-shared --disable-threads --enable-languages=c,c++
Thread model: single

Not reproducible using x86_64-pc-linux-gnu X m68k-none-elf.

Paul, is this still reproducible?

I also tried, gcc.c-torture/execute/920501-6.c, but I didn't get any ICE.

Original testcase above is reduced from
gcc.c-torture/execute/920501-6.c

I should mention why I marked this as a regression.  loop-unroll.c is new in
3.4.x.
