GDB 11.1 release prep update (2021-07-17)

GDB 11.1 release prep update (2021-07-17)

[Joel Brobecker]

Hi everyone,

Here is a quick update on the 11.1 release process. Quite a lot got
done in the past week, as you'll see below. Well done, and thank you!

I'm getting increasingly concerned about the 3 issues listed in
the "Other Ongoing Items", namely:
  - AArch64 MTE fixes and corefile support
  - some Python-suport changes for the TUI interface
  - DW_AT_ranges with form DW_FORM_sec_offset problem
The reason for concern is the lack of apparent attention the associated
patches or PRs seem to be getting. Links below, for those who would
like to try to help.

Thank you!

    AArch64 MTE fixes and corefile support
    https://sourceware.org/bugzilla/show_bug.cgi?id=27909

      Status 2021-07-11:
        - 2 patches already approved
        - 1 patch under discussion -- looks like good progress between
          Pedro and Luis:

        - 1 patch waiting for review on non-AArch64 part:
          https://sourceware.org/pipermail/gdb-patches/2021-July/180537.html

  * [HannesD] some Python-suport changes for the TUI interface

       I'm getting concerned about this one, as there does not seem
       to have been a review on those patches since they were posted
       early June. There was a ping sent on June 29th.

    [PATCHv2 1/2] Implement locals TUI window
    https://sourceware.org/pipermail/gdb-patches/2021-June/179539.html
    (I think this patch should provide more information in the commit
    message about what its goal is)

    [PATCHv2 2/2] Use method children instead of to_string in pretty printers
    https://sourceware.org/pipermail/gdb-patches/2021-June/179540.html
    (same suggestion)

  * [TomDV/Simon] <PR gdb/28004>
    DW_AT_ranges with form DW_FORM_sec_offset problem
    https://sourceware.org/bugzilla/show_bug.cgi?id=28004

    Not a blocker for branching, but should be fixed before the release.


Not Critical, but Requested:
----------------------------

  * [SimonM as awesome supporter and reviewer] <PR gdb/24069>
    gdb on OSX Mojave hangs in darwin_decode_message
    https://sourceware.org/bugzilla/show_bug.cgi?id=24069

        I know that the state of GDB on MacOS is very poor at the moment,
        and so having this PR fixed for 11.1 would be very nice. I don't
        think this PR should block the release, though. This is not new,
        and I'm not sure whether we can expect for us to converge without
        too much delay. There are good signs, though, with regular
        activity on the PR, lately. So let's see how it goes...

  * [BerndE] Improve debugging of optimized code
    https://sourceware.org/pipermail/gdb-patches/2021-January/175617.html

    https://sourceware.org/pipermail/gdb-patches/2021-May/179191.html

    No movement since then. Not blocking for branching since it would
    be safe to backport after branching. Not blocking for release either.

    This is the submission in question:
    https://sourceware.org/pipermail/gdb-patches/2020-November/173182.html

    For me, although I am not a lawyer, I don't think we can accept
    the contribution without the author signing a copyright assignment
    form.

The change proposed by Tom in the bug is probably good, on of us needs
to put it in patch form and send it.
