Doug Gregor	4808ed3001	[IRGen] Fix miscount for protocol requirements involving marker protocols. ... We had an imbalance where we counted conformance requirements to marker protocols in the number of requirements in a protocol's requirement signature, but then did not emit the requirement. Don't count them, either.	2021-02-19 23:39:42 -08:00

Doug Gregor	c9d66f0d35	Add "marker" protocols, indicated by @_marker. ... A marker protocol is a protocol with no requirements and with no ABI footprint. They can be used to indicate semantics, only, and one can never have values of a marker protocol type. We still mangle marker protocols when they are used as generic requirements, because they are a distinguishing characteristic for overloading, but "no ABI footprint" means no protocol descriptors, conformance descriptors, or dynamic discovery of any kind.	2021-02-02 21:53:26 -08:00
