Implement Bug 46698, making ODS synthesize a getType() method that returns a specific C++ class for OneResult methods where we know that class. This eliminates a common source of casts in things like: myOp.getType().cast<FIRRTLType>().getPassive() because we know that myOp always returns a FIRRTLType. This also encourages op authors to type their results more tightly (which is also good for verification). I chose to implement this by splitting the OneResult trait into itself plus a OneTypedResult trait, given that many things are using `hasTrait<OneResult>` to conditionalize various logic. While this changes makes many many ops get more specific getType() results, it is generally drop-in compatible with the previous behavior because 'x.cast<T>()' is allowed when x is already known to be a T. The one exception to this is that we need declarations of the types used by ops, which is why a couple headers needed additional #includes. I updated a few things in tree to remove the now-redundant `.cast<>`'s, but there are probably many more than can be removed. Differential Revision: https://reviews.llvm.org/D93790 |
