This converts the instances of the pattern for which we have a proper
substitution in lit. This will make it easier to replace it
appropriately with Windows equivalents.
Generic type specialization is ambiguous with < and > operators.
Extend the disambiguation hack to also consider parsing a generic
parameter list if the > is followed by &.
This fixes parsing types such as 'Base<Int> & P' in expression
context.
Now that SILGen can correctly lower lvalue accesses of
class existential payloads, remove a hack in Sema that
was simply doing the wrong thing.
Fixes <rdar://problem/31858378>.
The following instructions were enhanced with type dependent operands:
- convert_function
- pointer_to_thin_function
- upcast_inst
- thin_to_thick_function
Fixes rdar://31879356
There's an existing optimizer bug that is now exposed
involving function conversions. It does not appear
related to my changes.
I filed <rdar://problem/31879356> to track the issue.
