Stored value type does not match pointer operand type! store i8** %6, %1* %objects, align 8, !tbaa !​9 %"type 0x1040351f0"

Seems that we need a cast; %6 is most likely a call (running with master under a debugger indicates that the store is for a call).

compnerd commented 8 years ago

reduced.m Further reduced.

compnerd commented 8 years ago

This is a const conversion for the generic type that is failing to diagnose. Changing from a generic container to id seems to work. Assignment of const ObjectType to a NSObject const seems to trigger the assertion.

compnerd commented 8 years ago

reduced.m Reduced test case. The problem is a const check somewhere it seems.

Changing the NSObject * const * objects = [array objects]; to const NSObject * const * objects = [array objects]; allows the IRGen to succeed.
