C++ ABI Summary
- To: cxx-abi@xxxxxxxxxxxx
- Subject: C++ ABI Summary
- From: Jim Dehnert <dehnert@xxxxxxx>
- Date: Wed, 16 Jun 1999 00:58:08 -0700
Attached is a somewhat updated summary page -- I hope to
update it further before the meeting Thursday. Note that
the meeting is a different room -- about 2 rooms closer to
the front door, with yellow outer walls.
Welcome to two new participants: Daveed Vandevoorde from
Edison Design Group, and Colin McPhail from Edison Portable
Compilers.
Please take a look at the action items, and deal with them
if you can. Also, please check your contact information,
and send me corrections or missing information.
Also, I will send the open issues list shortly. I haven't
gotten issue summaries from anyone. Please try to get me
the ones you are listed for -- they needn't be long, or if
in rare cases they are, I'll settle for a brief summary now
and an update next week.
I have taken to sending these pages just in the HTML form,
because it's slightly easier and much smaller. If anyone
really prefers PDF, let me know and I'll go back to sending
both.
Jim

Note: When calling the SGI telephone bridges (starting 17 June),
the first caller continues to ring until the second party joins.
To get rid of it, you can call from a second phone,
and I believe you can hang it up right away.

<h4> Objectives </h4>
<ul>
<p>
<li>
Interoperable C++ compilation on IA-64:
we want users to be able to build relocatable objects with
different compilers and link them together,
and if possible even to ship common DSOs.
This objective implies agreement on:
<ul>
<li> Data representation
<li> Object file representation
<li> Library API
</ul>
<p>
<li>
ISO Standard C++:
highest priority is functionality and performance of standard-compliant code.
It should not be sacrificed for the benefit of language extensions or
legacy implementations (though considering them as tie-breakers is fine).
<p>
<li>
Some areas will be easier to agree on than others.
Our priorities should be based on achieving as much
interoperability as possible if we can't attain perfection.
That is, it is better to end up with a few restrictions being required
for interoperable code, than to have no interoperability at all.
This suggests priorities as follows:
<ol>
<li> Items requiring base ABI changes that might affect other
languages, and will therefore become impossible soon.
Examples include exception handling / stack unwind,
or ELF changes (not extensions).
<li> Core features where differences will prevent virtually any
C++ object code from porting.
Examples include data layout and calling conventions.
<li> Limited usage features,
where users can achieve portability by avoiding the feature.
An example might be multi-threading.
<li> Peripheral features,
where the requirements on users to achieve
portability are clear and easy to implement.
An example is non-explicit inlining,
where compilers would presumably allow it to just be suppressed.
<li> Tool interfaces, which affect how users build code,
rather than what they build.
An example is the compilation command line.
</ol>
<p>
<li>
Mechanisms/methods which allow coexistence of incompatible
implementations may be suitable in some cases.
For instance, packaging vendor-specific compiler support runtimes
in DSOs occupying distinct namespaces might allow multiple such DSOs to
be loaded for mixed objects and avoid requiring that all vendors have
the same support runtimes.
</ul>

<h4>Notes from 3 June 1999 </h4>
<ul>
<p>
<li> Introductions
<p>
<li> Objectives: see above
<p>
<li> Procedure
<ul>
<li> Meetings: 10-12 Thursdays at SGI for the near term.
<li> Intel NDA: Generally unnecessary. Priti will set up n-way
for eligible members for cases where needed. Cary expects RT
architecture/software conventions document to be released in the
next month or two, removing most of the issues.
<li> Communication: Use of reflector encouraged for discussion.
NDA communication will be handled with password-protected PDF
once Intel sets up n-way.
<li> Available documents: Parties with existing, relevant documents
(includes Sun, HP) will send them to group.
<li> Intellectual property: Participants don't expect problems with
release of any of their IP. Microsoft has extensive patents in
the area, but they are excessively broad (covering obvious ideas
and prior art), so expectation is that they are not a problem.
Nonetheless, we should be aware of them.
</ul>
<p>
<li> Issue Identification: new issues reflected in status table.
</ul>
