Looking more closely at sms-6.c it seems there is another issue which causes
SMS to FAIL in the loop in foo function:
Although the restrict keyword is attached to the pointers dependence edges are
created between the write and read. (Please see the SMS dump file)
The edges were not created in -r146278.
I used -O2 -fmodulo-sched -fdump-rtl-sms  -fno-auto-inc-dec -mno-update to
compile on PowerPC.
