| |
| function Build_Elementary_Input_Call (N : Node_Id) return Node_Id; |
| -- Build call to Read attribute function for elementary type. Also used |
| -- for Input attributes for elementary types with an appropriate extra |
| -- assignment statement. N is the attribute reference node. |
| |
| function Build_Elementary_Write_Call (N : Node_Id) return Node_Id; |
| -- Build call to Write attribute function for elementary type. Also used |
| -- for Output attributes for elementary types (since the effect of the |
| -- two attributes is identical for elementary types). N is the attribute |
| -- reference node. |
| |
| function Build_Stream_Attr_Profile |
| (Loc : Source_Ptr; |
| Typ : Entity_Id; |
| Nam : Name_Id) |
| return List_Id; |
| -- Builds the parameter profile for the stream attribute identified by |
| -- the given name (which is the underscore version, e.g. Name_uWrite to |
| -- identify the Write attribute). This is used for the tagged case to |
| -- build the spec for the primitive operation. |
| |
| -- The following routines build procedures and functions for stream |
| -- attributes applied to composite types. For each of these routines, |
| -- Loc is used to provide the location for the constructed subprogram |
| -- declaration. Typ is the base type to which the subprogram applies |
| -- (i.e. the base type of the stream attribute prefix). The returned |
| -- results are the declaration and name (entity) of the subprogram. |
