[LoopBoundSplit] Check the start value of split cond AddRec

2021-09-13T09:32:35+00:00

After transformation, we assume the split condition of the pre-loop is always
true. In order to guarantee it, we need to check the start value of the split
cond AddRec satisfies the split condition.

[LoopBoundSplit] Ignore phi node which is not scevable

There was a bug in LoopBoundSplit. The pass should ignore phi node which is not
scevable.

[SimpleLoopBoundSplit] Split Bound of Loop which has conditional branch with IV

2021-06-07T09:55:25+00:00

This pass transforms loops that contain a conditional branch with induction
variable. For example, it transforms left code to right code:

                             newbound = min(n, c)
 while (iv < n) {            while(iv < newbound) {
   A                           A
   if (iv < c)                 B
     B                         C
   C                         }
 }                           if (iv != n) {
                               while (iv < n) {
                                 A
                                 C
                               }
                             }
