This removes the builtin FunctionType, replacing it with a FunctionType instruction. The constant for a FunctionDecl is now a StructValue with type of FunctionType. Note this means a function declaration produces _both_ a type, and a value of the type. This has some consequences in terms of circularity, and makes the importing of function declarations a little more complex. It'll get particularly peculiar for imports because of the behavior of the reference, but that's a known issue due to other things such as `alias`. The impact will hopefully be contained to ResolvePrevInstForMerge (and ImportRefs). To note a small formatting change in diagnostics: ``` - // CHECK:STDERR: fail_member_lookup.carbon:[[@LINE+4]]:3: ERROR: Value of type `<associated <function> in Interface>` is not callable. + // CHECK:STDERR: fail_member_lookup.carbon:[[@LINE+4]]:3: ERROR: Value of type `<associated F in Interface>` is not callable. - // CHECK:STDERR: fail_todo_facet_lookup.carbon:[[@LINE+4]]:3: ERROR: Value of type `<associated <function> in Interface>` is not callable. + // CHECK:STDERR: fail_todo_facet_lookup.carbon:[[@LINE+4]]:3: ERROR: Value of type `<associated F in Interface>` is not callable. ``` --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>
