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!
