GDB 9.1 release -- 2020-01-02 update

[Joel Brobecker]

Hi everyone,

Happy New Year! Am I the only one wondering where the End of Year
Holidays went?!?

Quick status update, based on feedback for the branch, so far.

Added since the last update:

  - [Joel/Tom/Simon] Report error if trying to build GDB in tree
    https://www.sourceware.org/ml/gdb/2019-12/msg00034.html

    I think this is an acceptable limitation, but we haven't really
    made the official decision that it is. If we do, then we can
    patch configure to just report a clear error.

    Tom suggested an alternative, which is to revert the gnulib
    move on the branch. From my perspective, this is less desirable,
    because it is a riskier move.

  - [Andrew] unexpected disassembly output in backtrace
    https://sourceware.org/ml/gdb-patches/2019-12/msg01007.html

  - [Christian] Unable to build GDB on recent MinGW due to _FORTIFY_SOURCE
    https://sourceware.org/ml/gdb-patches/2019-12/msg00787.html

    I hestitated a lot on the resolution of this issue, but
    in the end, I am OK with the proposed approach of not
    setting _FORTIFY_SOURCE on MinGW targets.

    I will send a comment on the thread in question.

Still Open:

  - [Eliz] libtcf fails to build on MinGW
    https://sourceware.org/bugzilla/show_bug.cgi?id=25155

    Problem reported to binutils on Dec 17th, but so far
    no answer as far as I can tell.
    https://sourceware.org/ml/binutils/2019-12/msg00277.html

    Joel to send a copy of the patch to binutils, which should
    make it easier for people to review, compared to a reference
    to a bugzilla entry. Plead if necessary ;-).

Fixed since the last update:

  - [EliZ] readline/colors.c build failure

        Caused by S_IXGRP and S_IXOTH not being defined on MinGW.

  - [EliZ] configure warning when checking for pthread-config

Cheers!

I responded in that thread.

Unrelated: should we try to get a fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=25190 in? The bug says
this is breaking cgdb. A patch was sent in
https://sourceware.org/ml/gdb-patches/2019-11/msg00859.html but it
seems like it needs work.

Let's add this one to the list indeed, at least for now. I'm not
entirely sure this should be blocking, since there is an easy
workaround, but we can give ourselves a chance to look into it.

Thanks for the pointer!
