Fix PR gdb/19858: GDB doesn't register the JIT libraries on attach

Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html

GDB currently fails to fetch the list of already-registered JIT
modules on attach.

Nothing is calling jit_inferior_init, which is what is responsible for
walking the JIT object list at init time.

Despite the misleading naming, jit_inferior_created_hook ->
jit_inferior_init is only called when the inferior execs.

This regressed with the fix for PR gdb/13431 (03bef283c2d3):
 https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which
removed the inferior_created (jit_inferior_created_observer)
observer.

Adding an inferior_created observer back fixes the issue.

In turn, this exposes a bug in jit_breakpoint_re_set_internal as well,
which is returning the wrong result when we already have the
breakpoint at the right address.

a038fa3e14a4 stack: check frame_unwind_caller_id
2f3ef606b912 frame: add skip_tailcall_frames

In skip_artificial_frames we repeatedly call get_prev_frame_always until we get
a non-inline and non-tailcall frame assuming that there must be such a frame
eventually.

For record targets, however, we may have a frame chain that consists only of
artificial frames.  This leads to a crash in get_frame_type when dereferencing a
NULL frame pointer.

Change skip_artificial_frames and skip_tailcall_frames to return NULL in such a
case and modify each caller to cope with a NULL return.

In frame_unwind_caller_pc and frame_unwind_caller_arch, we simply assert that
the returned value is not NULL.  Their caller was supposed to check
frame_unwind_caller_id before calling those functions.

In other cases, we thrown an error.

In infcmd further move the skip_tailcall_frames call to the forward-stepping
case since we don't need a frame for reverse execution and we don't want to fail
because of that.  Reverse-finish does make sense for a tailcall frame.

PR remote/19496, internal err forking-threads-plus-bkpt

This patch fixes an internal error that occurs in
gdb.threads/forking-threads-plus-breakpoint.exp:

/blah/binutils-gdb/gdb/target.c:2723: internal-error: Can't determine the
current address space of thread Thread 3170.3170

In default_thread_address_space, find_inferior_ptid couldn't find 3170.3170
because it had been overwritten in inferior_appeared, called as follows:

inferior_appeared
  remote_add_inferior
    remote_notice_new_inferior
      remote_update_thread_list

The cause of the problem was the following sequence of events:

* GDB knows only about the main thread

* the first fork event is reported to GDB, saved as pending_event

* qXfer:threads:read gets the threads from the remote.
  remove_new_fork_children id's the fork child from the pending event
  and removes it from the list reported to GDB.  All the rest of the
  threads, including the fork parent, are added to the GDB thread list.

* GDB stops all the threads.  All the stop events are pushed onto the
  stop reply queue behind the pending fork event.  The fork waitstatus
  is saved in the fork parent thread's pending status field
  thread_info.suspend.

* remote_wait_ns calls queued_stop_reply and process_stop_reply to
  remove the fork event from the front of the stop reply queue and save
  event information in the thread_info structure for the fork parent
  thread.  Unfortunately, none of the information saved in this way is
  the fork-specific information.

* A subsequent qXfer:threads:read packet gets the thread list including
  the fork parent and fork child.  remove_new_fork_children checks the
  thread list to see if there is a fork parent, doesn't find one, checks
  the stop reply queue for a pending fork event, doesn't find one, and
  allows the fork child thread to be reported to GDB before the fork
  event has been handled.  remote_update_thread_list calls
  remote_notice_new_thread and overwrites the current (main) thread in
  inferior_appeared.

So the fork event has been reported out of target_wait but it was left
pending on the infrun side (infrun.c:save_waitstatus).  IOW, the fork
event hasn't been processed by handle_inferior_event yet, so it hasn't
made it to tp->pending_follow yet.

The fix is to check thread_info.suspend along with the
thread_info.pending_follow in remote.c:remove_new_fork_children, to
prevent premature reporting of the fork child thread creation.

breakpoints/19546: Fix crash after updating breakpoints

One of the last checks update_breakpoints_after_exec does while looping
over the list of breakpoints is check that the breakpoint has a valid
location spec. It uses event_location_empty_p to check if the location spec
is "empty", and if it is, the breakpoint is deleted.

momentary_breakpoint types rely on setting the breakpoint structure's
location spec to NULL, thereby causing an update to delete the breakpoint.
However, event_location_empty_p assumed that locations were never NULL.
As a result, GDB would crash dereferencing a NULL pointer whenever
update_breakpoints_after_exec would encounter a momentary_breakpoint.

This patch creates a new wrapper/helper function which tests that the given
breakpoint's location spec is non-NULL and if it is not "empty"
or "unspecified."

9 years agoRefactor string_to_event_location for legacy linespec support.
Keith Seitz [Tue, 9 Feb 2016 18:02:53 +0000 (10:02 -0800)] 
Refactor string_to_event_location for legacy linespec support.

This patch refactors string_to_event_location, breaking it into two
separate functions:

1) string_to_event_location_basic
A "basic" string parser that implements support for "legacy" linespecs
(linespec, address, and probe locations).  This function is intended to
be used by any UI wishing/needing to support this legacy behavior.

2) string_to_event_location
This is now intended as a CLI-only function which adds explicit location
parsing in a CLI-appropriate manner (in the form of traditional option/value
pairs).

Together these patches serve to simplify string-to-event location parsing
for all existing non-CLI interfaces (MI, guile, and python).

* location.c (string_to_explicit_location): Note that "-p" is

Fix PR19548: Breakpoint re-set inserts breakpoints when it shouldn't

PR19548 shows that we still have problems related to 13fd3ff34329:

 [PR17431: following execs with "breakpoint always-inserted on"]
 https://sourceware.org/ml/gdb-patches/2014-09/msg00733.html

The problem this time is that we currently update the global location
list and try to insert breakpoint locations after re-setting _each_
breakpoint in turn.

Say:

 - We have _more_ than one breakpoint set.  Let's assume 2.

 - There's a breakpoint with a pre-exec address that ends up being an
   unmapped address after the exec.

 - That breakpoint is NOT the first in the breakpoint list.

Then when handling an exec, and we re-set the first breakpoint in the
breakpoint list, we mistakently try to install the old pre-exec /
un-re-set locations of the other breakpoint, which fails:

 (gdb) continue
 Continuing.
 process 28295 is executing new program: (...)/execl-update-breakpoints2
 Error in re-setting breakpoint 1: Warning:
 Cannot insert breakpoint 2.
 Cannot access memory at address 0x1000764

 Breakpoint 1, main (argc=1, argv=0x7fffffffd368) at /home/pedro/gdb/mygit/src/gdb/testsuite/gdb.base/execl-update-breakpoints.c:34
 34        len = strlen (argv[0]);
 (gdb)

Fix this by deferring the global location list update till after all
breakpoints are re-set.

Tested on x86_64 Fedora 20, native and gdbserver.
