The -fsched-pressure option changes the value returned by rs6000_issue_rate which in turn affects the computed initiation interval in the SMS code and leads to failure to modulo schedule the single loop in sms-3.c and 1 of the 3 loops in sms-6.c. This patch adds that option for powerpc and is a precursor to a patch I'll submit shortly that enables -fsched-pressure by default for the rs6000 port.
