John McCall	3ce1ba3e65	Only store the minimal requirements in generic metadata, where ... "minimal" is defined as the set of requirements that would be passed to a function with the type's generic signature that takes the thick metadata of the parent type as its only argument.	2016-02-25 10:33:33 -08:00

Joe Groff	0b339b9a46	IRGen: Populate nominal type descriptor metadata for enums. ... Store the number of payload and no-payload cases, the case names, and a lazy case type accessor function for enums, like we do for stored properties of structs and classes. This will be useful for multi-payload runtime support, and should also be enough info to hack together a reflection implementation for enums. For dynamic multi-payload enums to not be ridiculously inefficient, we'll need to track the size of the payload area in the enum, like we do the field offsets of generic structs and classes, so hack off a byte in the payload case count to track the offset of that field in metadata records. 16 million payloads ought to be enough for anyone, right? (and 256 words between the enum metadata's address point and the payload size offset) Swift SVN r27789	2015-04-27 00:35:04 +00:00

Joe Groff	b8c75769b3	IRGen: Emit nominal type descriptors in struct and enum metadata. ... Build a nominal type descriptor when we emit the metadata or generic metadata pattern for a nominal type, and put a reference into the formerly null slot in the struct or enum metadata. We need to make a place for them in class metadata; that'll come next. Swift SVN r9492	2013-10-18 21:04:58 +00:00
Joe Groff	e109124186	Replace 'union' keyword with 'enum'. ... This only touches the compiler and tests. Doc updates to follow. Swift SVN r8478	2013-09-20 01:33:14 +00:00
