[15] RFR(M): 8240227: Loop predicates should be copied to unswitched loops

[Roland Westrelin]

Hi Christian,

I'm confused by that part of the change:

 242     if (iff->is_RangeCheck()) {
 243       // Only need to clone range check predicates as those can be changed and duplicated by inserting pre/main/post loops
 244       // and doing loop unrolling. Push the original predicate on a list to later process them in reverse order to keep the
 245       // original predicate order.
 246       if (predicate->outcnt() == 1) {
 247         // Clone all range checks that have no control to additional data nodes (like loop limit checks)
 248         list.push(predicate);

Comment line 247 mentions loop limit checks but they are not range
checks?

Roland.
