Florian Hahn 8d76ff9dd3 [LoopUnroll] Only peel if a predicate becomes known in the loop body.
If a predicate does not become known after peeling, peeling is unlikely
to be beneficial.

PowerPC The cost of splitting a large vector instruction is not being taken into account by the getUserCost function. This was leading to some loops being over unrolled. The cost of a vector instruction is now being multiplied by the cost of the type legalization. This will return a more accurate cost. 2017-10-19 18:16:31 +00:00
