strength reduction is performed in ivopts, introducing new variable:
for (p = inptr; p < something; p += 3)

Doloop: number of iterations too costly to compute.
I do not understand why as the number of iterations is max_cols and I
appreciate an explanation.
Thanks,
Revital

Hello,

tescase sms-4.c with mainline (-r 162294) due to 'Possible infinite
iteration

With an older version of gcc (-r 146278) doloop succeeded to be applied
