------- Comment #8 from pinskia at gcc dot gnu dot org  2009-09-25 08:10 -------
PPC has the same issue with -fno-schedule-insns:
test:
        stwu 1,-16(1)
        mflr 0
        stw 0,20(1)
        mr 0,3
        mr 5,4
        li 3,0
        mr 4,0
        bl foo
        lwz 0,20(1)
        addi 1,1,16
        mtlr 0
        blr
