John McCall	efd0dfbd70	Add the ability to use property-based serialization for "cased" types. ... This patch doesn't actually use this serialization for anything, but follow-ups will move the current handling of various standard types over to this.	2019-12-16 13:33:59 -05:00

John McCall	91dd67ef72	Introduce some types and functions to make it easier to work with ... the tblgen AST node hierarchies. Not totally NFC because both of the emitters now emit in a different order. The type-nodes emitter now visits nodes in hierarchy order, which means we could use range checks in classof if we had any types that would benefit from that; currently we do not. The AST-nodes emitter now uses a multimap keyed by the name of the record; previously it was using `Record*`, which of couse isn't stable across processes and may have led to non-reproducible builds in some circumstances.	2019-12-14 00:16:47 -05:00
