| // RemoveArrayLengthMethod.h: |
| // Fold array length expressions, including cases where the "this" node has side effects. |
| // Example: |
| // int i = (a = b).length(); |
| // int j = (func()).length(); |
| // becomes: |
| // (a = b); |
| // int i = <constant array length>; |
| // func(); |
| // int j = <constant array length>; |
| // |
| // Must be run after SplitSequenceOperator, SimplifyLoopConditions and SeparateDeclarations steps |
| // have been done to expressions containing calls of the array length method. |
| // |
| // Does nothing to length method calls done on runtime-sized arrays. |
