!summary

The new Ada 2005 predefined pragmas need to be added to Pragma_Kinds.

!question

The Amendment (Ada 2005) defines new pragmas for Ada; should these be added
to Pragma_Kinds? (Yes.)

!recommendation

(See summary.)

!wording

  - Add the new pragma values into type Pragma_Kinds (alphabetically): -- ASIS 3.9.2

       An_Assert_Pragma,			-- 11.4.2 (3)
       An_Assertion_Policy_Pragma,		-- 11.4.2 (6)
       A_Detect_Blocking_Pragma,		-- D.13 (4)
       A_No_Return_Pragma,			-- 6.5.1 (3)
       A_Partition_Elaboration_Policy_Pragma,	-- H.6 (3)
       A_Preelaborable_Initialization_Pragma,	-- 7.6 (5)
       A_Priority_Specific_Dispatching_Pragma,	-- D.2.2 (2.2)
       A_Profile_Pragma,			-- D.13 (2)
       A_Relative_Deadline_Pragma,		-- D.2.6 (2.2)
       An_Unchecked_Union_Pragma,		-- B.3.3 (3)
       An_Unsuppress_Pragma,			-- 11.5 (4.1)

"Alphabetically" means that the final list will be ordered alphabetically
(ignoring "An" or "A"). For instance, the first two items will be inserted
after An_All_Calls_Remote_Pragma; the last item will be inserted after
A_Task_Dispatching_Policy_Pragma.

Subject: Summary of the proposals for updating the ASIS Standard for Ada 2005
From: Sergey I. Rybin
Date: Mon, 13 Feb 2006 13:55:06 +0300

Formally the ASIS revision process is supposed to be started only after
finishing all the technical work with the new revision of the Ada Standard,
but I think we can start some preliminary technical work with new ASIS
definition already now (all the changes in Ada definition are stable
enough to start the ASIS revision).

At AdaCore we have developed a draft version of the new ASIS specification
and most of the proposed changes are already implemented in the latest
version of GNAT/ASIS technology. The attached file contains the summary
of the changes in the ASIS Standard we have made to adopt the new Ada
features. The interesting thing I've realized when working on
our draft of the new ASIS specification is that if we would like
to keep the upward compatibility as much as possible and if we
would like to keep changes as small as possible,
the new Ada definition gives us very limited freedom in making changes
in the ASIS spec. It does not mean that we think that our proposals
are the only possible solution for ASIS 2005, but it gives us some
hope that we can do ASIS revision for Ada 2005 fast enough.

There is quite a natural mapping of the proposed changes in the ASIS
specification onto the existing set of Ada Issues used for Ada revision,
and the attached file is structured and ordered by AIs. The only
exception is the new values in the ASIS Element Classification needed
to represent the new Ada 2005 predefined attributes and pragmas (of course,
this could be also mapped onto AIs, but I do not think that it would make
sense, because this is the easiest and completely straightforward part
of the ASIS revision).

My main goal of sending this ASIS 2005 Draft summary is to start
the ASIS 2005 discussion. The document itself would hardly be a convenient
background for this discussion - we will have at least split it on
changes related to different language issues, we will also have to
find a way for documenting the revision discussion, probably we
may need a separate mailing list for it. But let's get started!
