bootstrapped with your amended change to rs6000.c
./gcc/xgcc -Bgcc ../tests/hello.c -o hc -fstack-check -save-temps -fverbose-asm
-fdump-rtl-all
... shows that the stack check is present and correct ... 
any idea what test would produce the stack range check?

(make check is running - but will take some time).
