GDB 13 release -- 2022-10-09 Update

[Joel Brobecker]

Hello,

Here is a quick update on all the items currently on our radar
for GDB 13.

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

  <none>

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

  * [Torbjörn] PR gdb/28549
    ARM/Cortex-M: improper stack unwinding when the target is in lockup state
    https://sourceware.org/bugzilla/show_bug.cgi?id=28549

    Seems like there is a set of patches, but not entirely clear on
    where the latest version is located, and whether they have been
    approved or not.

    Seems to be blocked by FSF copyright assignment paperwork.

    I will ask for the motivations behind requesting this patch be
    included in GDB 13.

  * [Torbjörn]
    gdb/arm: Handle lazy FPU state preservation

    Patch has been approved by Luis; open question about whether
    we can accept it or not (FSF copyright assignment).

Other Ongoing Items:

    Show locno for 'multi location' breakpoint hit msg+conv var $bkptno $locno

  * [TomT] PR symtab/29105
    new DWARF reader still slow
    https://sourceware.org/bugzilla/show_bug.cgi?id=29105

    The subject of this PR and the initial message mention that
    the index cache is still faster than the new DWARF reader.
    But reading following discussions, it's not clear to me
    anymore what this ticket is about, or what's left to do.
    I will follow up on the PR itself.

  * [TomT] PR symtab/29106
    new DWARF reader should de-duplicate functions
    https://sourceware.org/bugzilla/show_bug.cgi?id=29106

  * [TomT] PR symtab/29179
    .gdb_index support for Ada
    https://sourceware.org/bugzilla/show_bug.cgi?id=29179
