Dear all,
Currently loop Interchange does not support loops with either more than one
inner loop induction variable or more than one outer loop induction
variable. The legality check just returns false if we encounter such cases.
I'm wondering if there is any particular reason behind? Also is it
preferred to add that support, i.e., enable loop interchange with more than
one induction variable?
Best regards,
Congzhe Cao
