This is caused by generating a complex linear offset in the transformed loop,
which the "back to gcc" converter doesn't handle ATM, since they were never
generated before.
(I didn't completly minimize linear offset generation. If i did, you'd notice
that this loop really goes from 5 to MAX (2, j) or something like that)
Loop w
step size = -1
linear offset:
Linear expression: -i + j constant: 5 invariants: denominator: 1
lower bound:
Linear expression: i - j constant: 0 invariants: denominator: 1
upper bound:
Linear expression: i - j constant: -3 invariants: denominator: 1
Linear expression: i constant: -5 invariants: denominator: 1
