[gdbserver/LynxOS]: Incomplete thread list after --attach

The current implementation is forgetting to populate the thread list
when attaching to the process. This results in an incomplete list of
threads when debugging a threaded program.

Unfortunately, as the added comments hints, there appears to be
no way of getting the list of threads via ptrace, other than by
spawning the "ps" command, and parsing its output. Not great,
but it appears to be the best we can do.

gdb/gdbserver/ChangeLog:

        * lynx-low.c (lynx_add_threads_after_attach): New function.
        (lynx_attach): Remove call to add_thread.  Add call to
        lynx_add_threads_after_attach instead.

[ELinOS] Best effort to load system libraries in case of incomplete env

So far elinos.py was assuming that the whole ELinOS environment was
around to find the system libraries; if some environment variables
were missing, the script would just abort.

This was a bit extreme. It is possible to do better than that: to get
the core system libraries, one doesn't need to have a full environment
but just the path to the CDK. The path to kernel project is only
needed for the optional Xenomai libs.

gdb/ChangeLog:

* system-gdbinit/elinos.py (get_elinos_environment): Return an
incomplete dictionnary instead of None in case of missing
environment variables.
(elinos_init): in case of an incomplete environment, best
effort to load system libraries instead of abort.

wrong "catch exception" error message when finding trampoline msym.

When building the program with the shared GNAT runtime, the debugger
is unable to insert Ada exception catchpoints until that runtime
has been mapped to memory. In other words, we expect the user to start
the program first, before attempting to insert that catchpoint.

The detection mechanism that tries to provide some useful tips to
the user fails when the program itself contains a trampoline symbol
matching the symbol that the catchpoint is trying to use. This
results in the following error message:

    (gdb) catch exception
    Your Ada runtime appears to be missing some debugging information.
    Cannot insert Ada exception catchpoint in this configuration.

Instead, we expected the following error message:

    (gdb) catch exception
    Unable to insert catchpoint. Try to start the program first.

gdb/ChangeLog:

        * ada-lang.c (ada_has_this_exception_support): Ignore
        mst_solib_trampoline minimal symbols.

gdb: btrace: fix build errors on older glibc builds

It is possible to have a build of glibc where SYS_perf_event_open is not
defined (because when the glibc was compiled, the syscall did not exist),
but have newer kernel headers installed so that linux/perf_event.h is
available.  In this setup, you get a build failure:

./common/linux-btrace.c: In function 'kernel_supports_btrace':
./common/linux-btrace.c:316:23: error: 'SYS_perf_event_open' undeclared (first use in this function)

Fix regular /path/to/directory sysroots and target reported dll paths with drive specs.

I tried debugging a remote Windows program on Linux host, and pointed the
sysroot to "/some/path/" rather than "remote:", and I found GDB couldn't
find the dlls in the sysroot.  If the dll name is
"C:/Windows/system32/ntdll.dll", I end up with the sysroot+in_pathname
concatenated this way:

 (top-gdb) p temp_pathname
 $1 = 0x228b690 "/some/pathC:/Windows/system32/ntdll.dll"
                          ^^

That is, a directory separator is missing.  This is a regression.

The problem is that solib_find decides that since the target path has
a drive spec, a separator is not necessary, which is clearly wrong in
this case.  That check was added in
<https://sourceware.org/ml/gdb-patches/2013-06/msg00028.html>, to
handle the case of sysroot being "remote:".  This patch fixes that
original issue in a different way.  Instead of checking whether the
path has a drive spec, check whether the sysroot is "remote:".  The
patch adds a table that helps visualize the cases that need a
separator.  I also confirmed the original issue is still handled as
expected.  That is, that "set sysroot remote:" still does the right
thing.

remote_filename_p returns true if the filename is prefixed with
"remote:".  In this case, we need to check whether the filename is
exactly "remote:".  I thought of different ways or either changing
remote_filename_p or adding another convenience function to remote.c
to avoid exposing the "remote:" prefix out of remote.c.  But all
attempts turned out adding lot of over needless complication.  So the
patch just exposes the prefix behind a new macro, which allows using a
straighforward strcmp.

This reverts the non-windows-specific part of the change called:
    amd64-windows: 32 bytes allocated on stack by caller for integer
    parameter regs
(the x64-windows portion has already been reverted)

gdb/ChangeLog:

        Revert:
        * i386-tdep.h (struct gdbarch_tdep): Add new field
        integer_param_regs_saved_in_caller_frame.
        * amd64-tdep.c (amd64_push_dummy_call): Allocate some memory on
        stack if tdep->integer_param_regs_saved_in_caller_frame is set.

Reimplement function calls on amd64-windows

This patch provides a standalone implementation of function calls
on amd64-windows, instead of providing some bits and pieces hooking
into the function call implementation meant for sysV (in amd64-tdep).
It makes better sense to do it this way, because the two ABIs are
actually very different; for instance, the concept of argument
classification, which is so central in the sysV ABI and drove the
the implementation in amd64-tdep, makes no sense for Windows. It
is therefore better for the Windows implementation to be completely
separate, rather than rely on adaptations of the sysV implementation.

gdb/ChangeLog:

        * amd64-tdep.c: #include "value.h"
        (amd64_windows_classify): Delete.
        (amd64_windows_passed_by_integer_register)
        (amd64_windows_passed_by_xmm_register)
        (amd64_windows_passed_by_pointer)
        (amd64_windows_adjust_args_passed_by_pointer)
        (amd64_windows_store_arg_in_reg, amd64_windows_push_arguments)
        (amd64_windows_push_dummy_call): New functions.
        (amd64_windows_init_abi): Remove setting of
        tdep->call_dummy_num_integer_regs, tdep->call_dummy_integer_regs,
        tdep->classify, tdep->memory_args_by_pointer and
        tdep->integer_param_regs_saved_in_caller_frame.
        Add call to set_gdbarch_push_dummy_call.

* readline.c (bind_arrow_keys_internal):

Fix regressions caused by thread-specific breakpoint deletion.

The recent change to make GDB auto-delete thread-specific breakpoints
when the corresponding thread is deleted
(https://sourceware.org/ml/gdb-patches/2013-09/msg00038.html) caused
gdb.base/nextoverexit.exp to regress.

    Breakpoint 1, main () at .../gdb/testsuite/gdb.base/nextoverexit.c:21
    21        exit (0);
    (gdb) next
    [Inferior 1 (process 25208) exited normally]
    Thread-specific breakpoint -5 deleted - thread 1 is gone.
    Thread-specific breakpoint -6 deleted - thread 1 is gone.
    Thread-specific breakpoint -7 deleted - thread 1 is gone.
    Thread-specific breakpoint 0 deleted - thread 1 is gone.
    (gdb) FAIL: gdb.base/nextoverexit.exp: next over exit (the program exited)

We shouldn't be seeing this for internal or momentary breakpoints.  In
fact, we shouldn't even be trying to delete them, as whatever created
them will take care or it, and therefore it's dangerous to delete them
behind the creator's back.

I thought it'd still be good to tag thread-specific internal/momentary
breakpoints such that we'll no longer try to keep them insert in the
target, as they'll cause stops and thread hops in other threads, so I
tried disabling them instead.  That caused a problem when following a
child fork, and detaching from the parent, as we try to reset the
step-resume etc. breakpoints to the new child's thread
(breakpoint_re_set_thread), after the parent thread is already gone
(and the breakpoints are marked disabled).  I fixed that by
re-enabling internal/momentary breakpoints there, but, that didn't
feel super safe either (maybe we'd need a new flag in struct
breakpoint instead, to tag the thread-specific breakpoint as "not to
be inserted").  It felt like I was heading down a design rat hole,
and, other things will usually delete internal/momentary breakpoints
soon enough, so I left that little optimization for some other day.

So, internal/momentary breakpoints are no longer deleted/disabled at
all, and we end up with a one-liner fix.

Tested on x86_64 Fedora 17.

in <https://sourceware.org/ml/gdb-patches/2008-08/msg00175.html>, I
introduced a bug.

The change was:

   else
     {
-      int tid = PIDGET (thread_id_to_pid (atoi (args)));
+      int tid = ptid_get_tid (thread_id_to_pid (atoi (args)));
       if (tid < 0)
  error (_("Thread ID %s not known.  Use the \"info threads\" command to\n"
         "see the IDs of currently known threads."), args);

and thread_id_to_pid does:

 ptid_t
 thread_id_to_pid (int num)
 {
   struct thread_info *thread = find_thread_id (num);

   if (thread)
     return thread->ptid;
   else
     return pid_to_ptid (-1);
 }

(pid_to_ptid (-1) is the same as minus_one_ptid.)

So before, we were really looking at the pid, where thread_id_to_pid
stores the -1.

The right fix is to compare the whole ptid to minus_one_ptid, of
course.

Completely untested, but I think it's obvious enough, so I went ahead
and put it in.

PR gdb/11568 - delete thread-specific breakpoints on thread exit

PR gdb/11568 is about thread-specific breakpoints being left behind
when the corresponding thread exits.

Currently:

 (gdb) b start thread 2
 Breakpoint 3 at 0x400614: file thread-specific-bp.c, line 23.
 (gdb) b end

 4       breakpoint     keep y   0x000000000040061f in end at thread-specific-bp.c:29
         breakpoint already hit 1 time

Note that the thread-specific breakpoint 3 stayed around, even though
thread 2 is gone.

There's no way that breakpoint can trigger again (*), so the PR argues
that the breakpoint should just be removed, like local watchpoints.
I'm ambivalent on this -- it could be reasonable to disable the
breakpoint (kind of like breakpoint in shared library code when the
DSO is unloaded), so the user could still use it as visual template
for creating other breakpoints (copy/paste command lists, etc.), or we
could have a way to change to which thread a breakpoint applies.  But,
several people pushed this direction, and I don't plan on arguing...

(*) - actually, there is ...  thread numbers are reset on "run", so
the user could do "break foo thread 2", "run", and expect the
breakpoint to hit again on the second thread.  But given gdb's thread
numbering can't really be stable, that'd only work sufficiently well
for thread 1, so we'd better call it unsupported.

So with the patch, whenever a thread is deleted from GDB's list, GDB
goes through the thread-specific breakpoints and deletes corresponding
breakpoints.  Since this is user-visible, GDB prints out:

  Thread-specific breakpoint 3 deleted - thread 2 is gone.

And of course, we end up with:

 (gdb) info breakpoints

 2       breakpoint     keep y   0x0000000000400614 in start at thread-specific-bp.c:23

The issue is that print_stack_frame always sets the current sal to the
frame's sal.  print_frame_info (which print_stack_frame calls to do
most of the work) also sets the last displayed sal, but only if
print_what isn't LOCATION.  Now the call in question, from within
thread.c:print_thread_info, does pass in LOCATION as print_what, but
print_stack_frame doesn't have the same check print_frame_info has.
We could consider adding it, but setting these globals depending on
print_what isn't very clean, IMO.  What we have is two logically
distinct operations mixed in the same function(s):

  #1 - print frame, in the format specified by {print_what,
    print_level and print_args}.

  #2 - We're displaying a frame to the user, and I want the default
    sal to point here, because the program stopped here, or the user
    did some context-changing command (up, down, etc.).

So I added a new parameter to print_stack_frame & friends for point
#2, and went through all calls in the tree adjusting as necessary.

Tested on x86_64 Fedora 17.
