GDB 10 branching - 2020-07-18 Update

[Joel Brobecker <brobecker@adacore.com>]

Hi everyone,

As you will see in the report below, a lot of been fixed since
the last update, but also we've also added a lot of new items.
To allow the process to converge, I propose we stop accepting
new items that aren't deemed blocking for the release.

For those who have items listed below, if you are blocked or
waiting for a review, please start pinging after the usual
waiting period (2 weeks after initial send, and weekly thereafter).

For those of us who have experience with the areas of the code
that the patches below are waiting on, and you have some time
to review them, that would be very helpful.

Thank you, everyone!

    Fix POSIX-isms in gdb.base/shell.exp
    https://sourceware.org/pipermail/gdb-patches/2020-June/169865.html

    https://sourceware.org/pipermail/gdb-patches/2020-July/170232.html

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

  * [KevinB] <PR gdb/25631>
    GDB cannot access unwritten-to mmap'd buffer from core file
    https://sourceware.org/bugzilla/show_bug.cgi?id=25631

    https://sourceware.org/pipermail/gdb-patches/2020-July/170158.html

    Pedro sent minor comments on 2020-07-10, but is otherwise happy
    with the patch series, so hopefully it gets pushed soon.

  * [SandraL]
    testsuite: gdb_wrapper handling polluting source directory with .o files
    https://sourceware.org/pipermail/gdb-patches/2020-July/170224.html

    Touches gdb.exp. No review so far. Not critical, IMO, but would
    be nice to at least review the patch. This seems like a regression
    compared to GDB 9.

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

  * [TomT/HannesD] <PR win32/25302>
    Mismatching fstat() function calls in gdb_bfd_open() and cache_bstat()
    https://sourceware.org/bugzilla/show_bug.cgi?id=25302

    Latest discussion at:
    https://sourceware.org/pipermail/gdb-patches/2020-June/169670.html
    Tom said he hasn't had time to look at Pedro's reply, unfortunately.
    I'm not super confident that he'll have much time soon either.
    Should we start looking at Plan B?

  * [RainerO]
    Unify Solaris procfs and largefile handling
    https://sourceware.org/pipermail/gdb-patches/2020-June/169977.html

    Seems to require a fair amount of coordination. binutils approved
    that part of the patch. Waiting for a review on the GDB side (the part
    in config/ is only used by GDB, so we will review it on the GDB side
    as well).

  * [LudovicC (reported by Simon)]
    Add support for Guile 2.2
    https://sourceware.org/pipermail/gdb-patches/2020-June/169936.html

    Was reviewed by Simon, who conducted the best review he could
    considering he doesn't know the area of the code well enough.
    We've been waiting for a more experienced maintainer to comment,
    with no success, so I suggested we go with Simon's review.

  * [EliZ]
    binutils: libctf build failure on Windows with mingw.org's MinGW
    https://sourceware.org/pipermail/gdb-patches/2020-July/170042.html

    2020-07-18: Joel just sent Nick a ping.

  * [ChristianB (reported by Eli)]
    Update gnulib to include fixes needed for mingw.org's MinGW
    https://sourceware.org/pipermail/gdb-patches/2020-June/169987.html
    https://sourceware.org/pipermail/gdb-patches/2020-July/170059.html

    On going, but good progress since.

  * [EliZ]
    gdbserver: incorrect socklen_t configure test on mingw.org's MinGW
    https://sourceware.org/pipermail/gdb-patches/2020-July/170019.html

    Eli and Joel exchanged patches, but I don't see anything having
    been officially submitted yet?

Not Critical, but Requested:
