PR 37790 doesn't solve the problem I see.
On SPU, with -O1 and -O2 -fno-schedule-insns the compilation time is long
(timed out == more than 5 minutes), but it's not as long as with -O2:
-O1 - 9.5 minutes.
-O2 -fno-schedule-insns - 10.5 minutes
-O2 - > 1000m
I don't know what can be done in order to improve compilation time on SPU, but
for sure - there is a problem in the insns shceduler.
