GDB 11 branching update (2021-06-13)

[Joel Brobecker <brobecker@adacore.com>]

Hey Team,

Here is another udpate of where we are. We've actually made more
progress than one might think by just looking at the number of items
alone, so last week was a good week. Keep it up :).


Fixed Since the Previous Update:
--------------------------------

  * [Simon] <PR gdb/27899>
    [GNU/Linux, sparc64] GDB crashes when debugging multithreaded programs
    https://sourceware.org/bugzilla/show_bug.cgi?id=27899


Added Since the Last Update:
----------------------------

  < none :) >

Other Ongoing Items:
--------------------

  * [TomDV] <PR symtab/26327>
    GDB hangs in get_builder() due to recursive ancestor pointers
    https://sourceware.org/bugzilla/show_bug.cgi?id=26327

    2021-06-09: Patch submitted:
    https://sourceware.org/pipermail/gdb-patches/2021-June/179750.html

  * [Simon/Kevin] <PR gdb/27526>
    Attaching to threaded process on glibc 2.33: libthread_db fails to initialize with "generic error"
    https://sourceware.org/bugzilla/show_bug.cgi?id=27526

    2021-06-10: Looks like we're getting close. New patch series from
    Kevin, with positive reviews (modulo minor comments or questions):
    https://sourceware.org/pipermail/gdb-patches/2021-June/179786.html

  * [RainerO] <PR binutils/27666>
    ar doesn't create indices on Solaris/sparcv9
    https://sourceware.org/bugzilla/show_bug.cgi?id=27666

    Causes large number of tests to fail in gdb's testsuite.

    2021-06-09: Binutils patch pushed to master should normally
    make the issue go away (waiting for confirmation):
    https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=f75bcf7e574c511f0ea742e05e5ae6e19bf29a92

  * [LuisM] <PR corefiles/27909>
    AArch64 MTE fixes and corefile support
    https://sourceware.org/bugzilla/show_bug.cgi?id=27909

  * [Bernd/PedroA/TomT] TUI issues from mouse-support patch
    https://sourceware.org/pipermail/gdb-patches/2021-June/179541.html

    Under discussion, but looks like there is good progress.
    It's a bit difficult for me to follow the discussions because
    I don't know TUI -- would you let me know when you think
    all blocking issues have been resolved?

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

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

  * [Sergey with Simon as reviewer] <PR tdep/26633>
    Add Z80 CPU support
    https://sourceware.org/bugzilla/show_bug.cgi?id=26633

    Patch submitted at:
    https://sourceware.org/pipermail/gdb-patches/2020-September/172083.html

    (May 24th) High-level pre-review done at:
    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.

  * [Simon] <PR gdb/26868>
    Follow-up on x86-64 stub submission
    https://sourceware.org/bugzilla/show_bug.cgi?id=26868

    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.

Thank you!
