Subject: GDB/MI - Possible missing stop-reason on attach or misleading documentation
Date: Thu, 3 Mar 2022 09:35:48 +0100	[thread overview]
Message-ID: <8a90c905-f238-0e14-ef7b-21c0eac58948@gnu.org> (raw)

When attaching to a running progress (that currently "waits" in 
`getchar()`, but that likely doesn't matter) in async mode the following 
records are returned:

=thread-group-started,id="i1",pid="12345"
=thread-created,id="1",group-id="i1"
=library-loaded,id=... many entries
~"0x00007fa0a626b7e0 in __read_nocancel () from /usr/lib64/libc.so.6\n"
*stopped,frame={addr="0x00007fa0a626b7e0",func="__read_nocancel",args=[],from="/usr/lib64/libc.so.6",arch="i386:x86-64"},thread-id="1",stopped-threads="all",core="1"

My understanding from
https://sourceware.org/gdb//onlinedocs/gdb/GDB_002fMI-Async-Records.html 
was that the reason field is _always_ returned.

Questions:
* Did I look at the right place of the docs?
* Are all fields listed there should always be filled?
   If not I highly suggest to add a note about that.
* Can the reason field be added in the attach case? I _guess_ that would
   be either "location-reached" or "breakpoint-hit".
