-- GENERAL NOTES PERTAINING TO ATTRIBUTES DEFINED HERE
--
-- There are three "implementation dependant" attributes documented in
-- the Appendix F found in the "Sun Ada 1.0 for Sun4 SunOS 4.x"
-- Programmer's Guide. These include:
--
-- X'Address,
-- X'Ref and System.Address'Ref(N), and
-- X'Task_Id
--
-- The implementation for the X'Address attribute is already provided
-- by the R1000 semanticist and is therefore not defined here.
--
-- 'Ref is "overloaded" in that it has two permitted forms. The form
-- X'Ref is used only in machine code insertions. Both forms could not
-- be implemented in the RCI. Because machine code insertions should be
-- used somewhat infrequently, this customization implements only the
-- System.Address'Ref(N) form.
--
-- In the case of both System.Address'Ref(N) and X'Task_Id a known bug
-- in the Rev1_0_0 release of the RCF prevents usages of these
-- attributes in a view using this customization from semantizing
-- properly. The bug has reportedly been fixed in the upcoming
-- maintanence release. Once this release becomes available, the use
-- of these attributes will have to be tested. It is believed that
-- they are properly defined here.
--
-- 'Ref has two permitted forms
--
-- X'Ref - Used only in machine_code procedures
-- X must be either a constant, variable, procedure, function, or
-- label.
-- Returns a value of type Machine_Code.Operand.
-- May be used only to designate an operand within a code-statement.
--
-- System.Address'Ref(N) - Used anywhere to convert the
-- Universal_Integer value N to an Address.
-- Returns a type of System.Address.
-- N must be a static value of type Universal_Integer.
--
-- Of the two permitted forms, only System.Address'Ref(N) is
-- implemented at this time.
