GCC-3.4.5 status report

- Subject: GCC-3.4.5 status report
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".
Happy hacking,
