| // 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. | |
