ada: Crash on creation of extra formals on type extension
The compiler blows up processing an overriding dispatching function
of a derived tagged type that returns a private tagged type that
has an access type discriminant.
gcc/ada/
* accessibility.ads (Needs_Result_Accessibility_Extra_Formal): New
subprogram.
* accessibility.adb (Needs_Result_Accessibility_Level_Param): New
subprogram.
(Needs_Result_Accessibility_Extra_Formal): New subprogram,
temporarily keep the previous behavior of the frontend.
* sem_ch6.adb (Create_Extra_Formals): Replace occurrences of
function Needs_Result_Accessibility_Level_Param by calls to
function Needs_Result_Accessibility_Extra_Formal.
(Extra_Formals_OK): Ditto.
