Humpf... Freeze_Enumeration_Type has this big comment:
-- Now we build the function that converts representation values to
-- position values. This function has the form:
-- function _Rep_To_Pos (A : etype; F : Boolean) return Integer is
-- begin
-- case ityp!(A) is
-- when enum-lit'Enum_Rep => return posval;
-- when enum-lit'Enum_Rep => return posval;
-- ...
-- when others =>
-- [raise Constraint_Error when F "invalid data"]
-- return -1;
-- end case;
-- end;
-- Note: the F parameter determines whether the others case (no valid
-- representation) raises Constraint_Error or returns a unique value
-- of minus one. The latter case is used, e.g. in 'Valid code.
-- Note: the reason we use Enum_Rep values in the case here is to avoid
-- the code generator making inappropriate assumptions about the range
-- of the values in the case where the value is invalid. ityp is a
-- signed or unsigned integer type of appropriate width.
