Slava Pestov	94ce4c2ac3	SIL: Only give closures shared linkage if they're going to be serialized ... Otherwise, we don't want them to be linkonce_odr at the LLVM level to avoid unnecessary link-time overhead.	2017-03-31 20:26:27 -07:00
Joe Groff	a7f23f5019	SIL: Canonicalize capture types with the AST function's generic signature. ... When lowering closures, we avoid capturing the enclosing generic context when possible. However, the generic context may still be necessary to canonicalize types mentioned inside the closure, such as when an associated type is referred to that is same-typed to a concrete type.
