The patch contained in
http://gcc.gnu.org/ml/gcc-patches/2004-12/msg00405.html
doesn't seem to work for me, rsp. triggers another ICE, at least the error
message seems to have changed:
With today's gcc/cvs-trunk + your patch applied:
# m68k-rtems4.7-gcc -W -Wno-unused -Wshadow -m5206e -O3 -fomit-frame-pointer
-funroll-loops -S -o tmp.s /tmp/safer.c
/tmp/safer.c: In function 'safer_ecb_encrypt':

(nil)))
/tmp/safer.c:2494: internal compiler error: in spill_failure, at reload1.c:1872
Also I am seeing a new ICE during building RTEMS, but I am not sure if this is
related to your patch.
