GCC-3.4.5 status report

GCC-3.4.5 status report

[Gabriel Dos Reis]

Hi,

  The SC has agreed me taking up the GCC-3.4.5 ball.
I'm planning for two releases from the GCC-3.4.x series this year:
    (a) GCC-3.4.5 on September 30, and 
    (b) GCC-3.4.6 on December, 15.

The number of bugs (regressions) currently targetted for 3.4.5 is
quite huge: 125 according to my counting and 150 according to
bugzilla-query; more on that later.   As usual, the C++ front-end is
the winner for the highest number of regressions.  Out of those, 7 have
been marked release-critical by bugmasters:

  rtl-optimization/11707           Zdenek Dvorak
  c/16676                          -
  c++/17655                        -
  c++/17972                        -
  middle-end/18956                 -
  c++/19208                        Giovanni Bajo
  c++/21232                        -

Where individual names appear, that bugzilla indicates they are
assigned the bug in question.

The full list of bugs is produced below.  Maintainers, please look
into any of those and see which ones you can fix or give guidance for
fixes in ways that are suitable for a stable branch.

Note to Dan:  bugzilla-query, for "index gcc * 3.4.5", reports that it
founds "150 bugs", where in fact only 125 are sent (and that number
matches what the web interface reports).  Would you be willing to
check bugzilla-query counts?  Thanks in advance.

From this week-end till end of August, I'll be travelling in
Europe.  Though I expect connectivity during that period of time, I may
temporarilly be kept away from machines and network during August 
15-22 (due to personal happy events!).  Thanks to Dan's improvement
for bugzilla-query, my mail agent will be watching
gcc-3.4.5-bug-related acitivities.

Note to all:  from now on, please consider any snapshot from GCC-3.4.x
as a release candidate, e.g.  please test them as you would for any
tarball I would have labelled "prerelease" or "release candidate".

Fixed.
It was counting a slightly higher number of bugs than it actually sent
(it does some of the query filtering client-side in the script)

Do I still have time / opportunity to refresh the SCO ports?
If Sept 30 is the deadline I will definately be able to make
it. I have the thing bootstrapping, and I am working my way
through the regression suites to understand and either fix,
or at least understand why I am ignoring, any failures.

This being a stable release branch, I'll consider only regressions 
fixes.  Is that the case?

I guess it depends on how pedantic we want to define
'regression'. I did a mostly-working port circa 3.4.1, but
it had some problems, but teh last known-to-be-working-well
port was 2.95.3. I have people baying for 3.4 all the time.
So its technicalyl a regression from 2.95.3, and almost one
from 3.4.1 :)

Here is how Mark and I have agreed on those sort of things.  If such a
patch is accepted in 3.4.x but not in 4.0.x, then we've introduced a
regression in 4.0.x. 
So, the way we deal with it is that, the patch is first applied to
4.0.x, then to 3.4.x retrospectively.  Is that workable for you?

(I applied a more enthusiastic policy for 3.3.3, but that is only
because of the particularity of the 3.3.x series when I took it).

Absolutely. I actually did all the workin in a 4.0.2 cvs tree, and
Im backporting it to my 3.4.5 tree.

This m68k patch:

  http://gcc.gnu.org/ml/gcc-patches/2005-07/msg00783.html

was approved here by the m68k maintainer:

  http://gcc.gnu.org/ml/gcc-patches/2005-07/msg01427.html

I believe those PRs are 3.4 regressions, despite not being
marked so in Bugzilla.  Fixing them is quite critical to
m68k users and doesn't affect other targets.

Am I still in time for 3_4-branch?

GCC-3.4.5 status report

[Gabriel Dos Reis]

Hi,

  Despite a number of bug fixing patches applied to gcc-3_4-branch
(special thanks to Richard Sandiford), the total count of bugs open
against GCC-3.4.5 only has increased from 115 (last report) to 117
(this morning).  That reflects a continual flux of incoming PRs for
GCC-3.4.x and bugs present in 3.4.5, 4.0.x and 4.1.x fixed in the
last two branches but not in 3.4.x.  As ever, the C++ front-end is the
winner of the usual contest.

I'll work on this, but i probably won't get to it till next week (best
guess).

GCC-3.4.5 status report

[Gabriel Dos Reis]

Hi,

  The number of open PRs registered as CC-3.4.x regressions only and
targetted for 3.4.5 has decreased from 125 (last week) to 115.  Which
is a progress!  Still, we have too many PRs  for a stable branch.

Here is the complete list as communicated to me by the bugzilla mail
interface.  Note to Dan: we still miss ways to query for PRs closed
in specific laps to time.  The C++ front-end remains the winner in the
category of maximum number of regressions (46).
