GDB 11 branching update (2021-06-20)

[Joel Brobecker]

Hello everyone,

Some good progress again last week. Down to two PRs left and two new
maybes added.


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

    GDB hangs in get_builder() due to recursive ancestor pointers
    https://sourceware.org/bugzilla/show_bug.cgi?id=26327

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

    PR not closed, but situation now back to where it was in previous
    release.

  * [HannesD/PedroA/TomT] TUI issues from mouse-support patch

    [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)


Other Ongoing Items:

    Patch pushed:
    https://sourceware.org/pipermail/gdb-patches/2021-June/179786.html
    Asked for confirmation on the PR that we're now OK to close.

  * [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.

Closed now.

I reported this which is a recent regression, so it should ideally be
looked at before the release:

  ASan crash when printing expression involving function call

Andrew looked into this one really quickly (thanks!), it will probably
be closed soon.

I however stumbled on another regression while looking at that:

    DW_AT_ranges with form DW_FORM_sec_offset problem
    https://sourceware.org/bugzilla/show_bug.cgi?id=28004

Not a blocker for the branching, but I'd say a blocker for the release.

Understood. Thanks for the update, Simon. They are very much appreciated!
