This testcase still has ICE with gcc trunk r194473.
ICE with both arm and thumb mode, using -O1 and -O2. No ICE when using -O3. ICE
with -march=armv7-a. ICE with -mcpu=cortex-a8 but no ICE for any other
cortex-a* cpu.

Unfortunately, because of the various failures related to modulo-sched on arm,
I haven't been able to track down the exact revision responsible for this ICE.
Regression test failure reported in PR55486 has the error message.
FAIL: gcc.dg/sms-7.c (internal compiler error)
