Do NOT touch FP ops with LSR. This fixes a testcase Nate sent me from an
inner loop like this:
LBB_RateConvertMono8AltiVec_2: ; no_exit
lis r2, ha16(.CPI_RateConvertMono8AltiVec_0)
lfs f3, lo16(.CPI_RateConvertMono8AltiVec_0)(r2)
fmr f3, f3
fadd f0, f2, f0
fadd f3, f0, f3
fcmpu cr0, f3, f1
bge cr0, LBB_RateConvertMono8AltiVec_2 ; no_exit
to an inner loop like this:
LBB_RateConvertMono8AltiVec_1: ; no_exit
fsub f2, f2, f1
fcmpu cr0, f2, f1
fmr f0, f2
bge cr0, LBB_RateConvertMono8AltiVec_1 ; no_exit
Doh! good catch!
