Hello all.
As many know, various linux distributors are working on re-compiling
their distros with GCC mainline in the hopes of helping GCC 4.3
stabilize. As part of this effort, many bugs have been filed in GCC
bugzilla, and many portability issues have been identified.
Attached is a rough cut of a detailed portability document for
GCC 4.3, compiled with the assistance of Fedora and Debian activists.
(Particular thanks to Jakub J and Martin Michlmayr). Currently it lists
the major issues each distribution has found when upgrading (minus ICE
type errors). It is our goal to have a detailed guide for users of GCC
who wish to upgrade, hosted on the gcc.gnu.org site. Although we'd
initially thought of putting this on the GCC wiki, the current thought
is a better placement would be to put this alongside the release notes,
ie:
http://gcc.gnu.org/gcc-4.3/changes.html
would be joined by
http://gcc.gnu.org/gcc-4.3/porting_to.html
This would imply that the porting document would be checked in to
wwwdocs and available to all the usual GCC contributors to edit and
update.
As such, I'd like to get a general indication from the greater GCC
community as to this plan. Does this document seem like a good idea?
(Previously, we've left this kind of document to the user community.
Often the passage of time has not been particularly kind to these
links.) Is the suggested placement ok for everybody?
If this is ok, some editing of duplicate info from changes.html should
take place. I volunteer to do this.
And, finally, we'd need an ok from the wwwdocs head dude, Gerald.
Thoughts and comments?
best,
benjamin

Fine with me; it should be linked from the "Caveats" section of
gcc-4.3/changes.html.

Saw one error:
-----------------------------
Another preprocessor warning change is for trailing whitespace after and #endif, code like:
#ifdef TEST
#endif TEST
-----------------------------
s/trailing whitespace after and/extra tokens after an/
It's, of course, legal to have trailing whitespace and comments after
an #endif.

I think this is a great idea. Thanks for writing it.

Sweet, that's really a nice one. Thanks for stepping up with this,
Benjamin.
In addition to the link from the gcc-4.3/changes.html page I'd also like
this to become a News item on the main page and we probably also will want
to add a link from gcc-4.3/index.html itself. Don't be shy. :-)

Looks good. I'll make a few comments below to avoid you getting hit by
the automatic web pages checker, and I hope the various maintainers will
also have a look at their respective domains but let's get this in!

No, it's badly worded, but fixing it seems to be more than a matter of
rephrasing. It's basically saying that existing warning flags will
produce warnings, but I'd prefer to see something more specific.
That is, what kinds of additional warnings should be expected?

^- s/warnings/additional warnings/, or maybe "fewer false
positives" as well.

" In addition, improvements to the GCC infrastructure allow
improvements in the ability of several existing warnings to
spot problematic code" ?

I would start with Dave's fix, and then see if we can improve it
somehow. Presumably this is talking about Manuel's work, at least
in part?

In part. Actually, the new warnings are all over the place.
I've attached a summary from:
http://sunsite.mff.cuni.cz/rawhide20071220-gcc43/Werror/
Please go ahead and improve this wording and substance. I've checked in
a revised copy to wwwdocs.

"If the old GNU extern inline behavior is desired, one can use extern
inline __attribute__((__gnu_inline__)). The use of this attribute can
be guarded by #ifdef __GNUC_STDC_INLINE__ which is a macro which is
defined when inline has the ISO C99 behavior, or compiled with
-fgnu89-inline option."
I think this is phrased a bit confusingly, the "or compiled with ..."
branch refers to the first sentence, but is part of the second
sentence which makes it seem like it's related to the macro.
This must be the english language equivalent of a dangling else.
The attached patch makes it clearer to me, does anyone agree?
