All the usages of find_inferior were removed, so the function itself can
be removed.
gdb/gdbserver/ChangeLog:
* inferiors.h (find_inferior): Remove.
* inferiors.c (find_inferior): Remove.
These functions were modified in the previous patch series, but I forgot
to update some comments.
gdb/gdbserver/ChangeLog:
* linux-low.c (resume_status_pending_p): Update comment.
(need_step_over_p): Update comment.
Replace with for_each_thread.
gdb/gdbserver/ChangeLog:
* linux-low.c (linux_resume_one_thread): Return void, take
parameter directly.
(linux_resume): Use for_each_thread.
Replace with find_thread/for_each_thread. I inlined the callbacks,
because they are relatively simple.
gdb/gdbserver/ChangeLog:
* linux-low.c (select_singlestep_lwp_callback): Remove.
(count_events_callback): Remove.
(select_event_lwp_callback): Remove.
(select_event_lwp): Use find_thread/for_each_thread.
Replace with find_thread. Writing a lambda inline in directly in the if
conditions would be a bit messy, so I chose to assign them to variables
instead.
gdb/gdbserver/ChangeLog:
* linux-low.c (not_stopped_callback): Return bool, take filter
argument directly.
(linux_wait_for_event_filtered): Use find_thread.
(linux_wait_1): Likewise.
Replace with find_thread. We could almost use find_thread_ptid, except
that find_lwp_pid uses the pid of the input ptid of the lwp is 0, so the
behavior is not quite the same.
gdb/gdbserver/ChangeLog:
* linux-low.c (same_lwp): Remove.
(find_lwp_pid): Use find_thread.
Replace with for_each_thread with pid filtering. The callback becomes
trivial enough that it's better to inline it.
gdb/gdbserver/ChangeLog:
* linux-low.c (delete_lwp_callback): Remove.
(linux_mourn): Use for_each_thread.
Replace it with find_thread. I also modified the code a bit to use a
lambda and a boolean.
gdb/gdbserver/ChangeLog:
* linux-low.c (struct counter): Remove.
(second_thread_of_pid_p): Remove.
(last_thread_of_process_p): Use find_thread.
Replace with for_each_thread with pid filtering. This allows
simplifying the callback a little bit.
gdb/gdbserver/ChangeLog:
* linux-mips-low.c (update_watch_registers_callback): Return
void, remove pid_p parameter, don't check for pid.
(mips_insert_point, mips_remove_point): Use for_each_thread.
Replace it with for_each_thread with pid filtering. We can remove
lynx_delete_thread_callback and pass remove_thread directly.
I can't build/test this change, but it should be obvious enough.
gdb/gdbserver/ChangeLog:
* lynx.low (lynx_delete_thread_callback): Remove.
(lynx_mourn): Use for_each_thread.
Replace with for_each_thread with pid filtering.
regcache_invalidate_one is not longer needed, as it was only used to
filter the pid. We can call regcache_invalidate_thread directly.
gdb/gdbserver/ChangeLog:
* regcache.c (regcache_invalidate_one): Remove.
(regcache_invalidate_pid): use for_each_thread.
This is the previously mentioned patch to get rid of
unstructured/ioctl-based procfs support in procfs.c. Given that support
for structured procfs was introduced in Solaris 2.6 back in 1997 and
we're just removing support for Solaris < 10, there's no point in
carrying that baggage (and tons of support for IRIX and OSF/1 as well)
around any longer.
Most of the patch should be straightforward (removing support for
!NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks).
Only a few points need explanations:
* <sys/syscall.h> was already included unconditionally in most places,
so there's no need to have guards in a few remaining ones.
* configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so
NEW_PROC_API detection for those in configure.ac can go.
* I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1.
Theoretically, it would be better to include <procfs.h> on Solaris
(which includes that define), but that breaks the build over
<procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux.
* I've regenerated syscall_table[] in proc-events.c with a small script
from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no
traces of older Solaris versions and other OSes left.
* prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX
doesn't use procfs.c any longer, so all related code can go.
The patch was generated with diff -w so one can easier see changes
without being distracted by simple reindentations.
So far, it has only been compiled and smoke-tested on
amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and
x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3
vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on
Solaris 10 etc.), but it's enough to get a first impression how much
cleanup is possible here.

(unsuspend_all_lwps): Use for_each_thread, inline code from

Replace find_inferior with find_thread. Since it may be useful in the
future, I added another overload to find_thread which filters based on a
ptid (using ptid_t::matches), so now iterate_over_lwps doesn't have to
do the filtering itself. iterate_over_lwps_filter is removed and
inlined into iterate_over_lwps.

This patch makes the syscalls_to_catch field of process_info an
std::vector<int>. The process_info structure must now be
newed/deleted.
In handle_extended_wait, the code that handles exec events destroys the
existing process_info and creates a new one. It moves the content of
syscalls_to_catch from the old to the new vector. I used std::move for
that (through an intermediary variable), which should have the same
behavior as the old code.
gdb/gdbserver/ChangeLog:

fields..

This fixes the issue reported by Dmitry Antipov <dantipov@nvidia.com>
here:
https://sourceware.org/ml/gdb/2017-10/msg00048.html
The problem is that GDBserver stops listening to Ctrl-C/interrupt
requests if you disconnect and reconnect back.

~~~
Currently gdbserver installs SIGIO handler just once, in
initialize_async_io() called from captured_main(), and this handler is
removed when remote_desc is closed in remote_close(). Next, when a
new instance of remote_desc is fetched from accept() and has '\003'
arrived, input_interrupt() is never called because it is not
registered as SIGIO handler.
~~~
The fix here is not remove the SIGIO handler in the first place, thus
going back to the original before-first-connection state.
(I haven't gone back to try it, but I think this was a regression
caused by commit 8b20733984 ("[GDBserver] Block and unblock SIGIO"),
which was what made remote_close remove the signal handler.)

This commit garbage collects the termio and sgtty support.
GDB's terminal handling code still has support for the old termio and
sgtty interfaces in addition to termios. However, I think it's pretty
safe to assume that for a long, long time, Unix-like systems provide
termios. GNU/Linux, Solaris, Cygwin, AIX, DJGPP, macOS and the BSDs
all have had termios.h for many years. Looking around the web, I
found discussions about FreeBSD folks trying to get rid of old sgtty.h
a decade ago:
https://lists.freebsd.org/pipermail/freebsd-hackers/2007-March/019983.html
So I think support for termio and sgtty in GDB is just dead code that
is never compiled anywhere and is just getting in the way. For
example, serial_noflush_set_tty_state and the raw<->cooked concerns
mentioned in inflow.c only exist because of sgtty (see
hardwire_noflush_set_tty_state).
Regtested on GNU/Linux.
Confirmed that I can still build Solaris, DJGPP and AIX GDB and that
the resulting GDBs still include the termios.h-guarded code.
Confirmed mingw-w64 GDB still builds and skips the termios.h-guarded
code.
