Mark Lacey	1f23ff27bb	Remove the transparent bit from apply instructions. ... We no longer need or use it since we can always refer to the same bit on the applied function when deciding whether to inline during mandatory inlining. Resolves rdar://problem/19478366.

Joe Groff	9489605a8f	Enable vtable thunks. ... Swift SVN r24736	2015-01-26 21:52:20 +00:00
Joe Groff	05290abeb4	SILGen: Reuse vtable thunks from base class. ... If a grandchild class inherits a thunked override from the child class, use that thunk in the grandchild vtable too. Should round out the fix for rdar://problem/19321484. Swift SVN r24735	2015-01-26 21:52:20 +00:00
Joe Groff	a449948275	SILGen: Emit vtable thunks to handle optional variance. ... If a subclass overrides methods with variance in the optionality of non-class-type members, emit a thunk to handle wrapping more optional parameters or results and force-unwrapping any IUO parameters made non-optional in the derived. For this to be useful, we need IRGen to finally pay attention to SILVTables, but this is a step on the way to fixing rdar://problem/19321484. Swift SVN r24705	2015-01-24 05:21:26 +00:00
