So far elinos.py was assuming that the whole ELinOS environment was

When building the program with the shared GNAT runtime, the debugger

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:

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.

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.

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.

Subject: [PATCH] [Hurd/gnu-nat.c] Use ptid_t.lwpid to store thread ids
instead of ptid_t.tid.
In preparation for reusing gnu-nat.c in gdbserver, switch to storing
thread ids in the lwpid field of ptid_t rather than in the tid
field. The Hurd's thread model is 1:1, so it doesn't feel wrong
anyway.

[Hurd/gnu-nat] Fix old "signal-thread" command regression.
By inspection, I noticed that when I made the gnu-nat use
ptid(pid,0,tid) to represent a thread, instead of using ptid(tid,0,0),
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.
