Notice how the third "si" didn't actually make progress.

Turning on infrun and lin-lwp debug, we see:

 (gdb)
 infrun: clear_proceed_status_thread (process 5252)
 infrun: proceed (addr=0xffffffffffffffff, signal=144, step=1)
 infrun: resume (step=1, signal=0), trap_expected=0, current thread [process 5252] at 0x323d4ba7c4

 LLW: enter
 LNW: waitpid(-1, ...) returned 5252, No child processes
 LLW: waitpid 5252 received Child exited (stopped)
 LLW: Candidate event Child exited (stopped) in process 5252.
 SEL: Select single-step process 5252
 LLW: exit
 infrun: target_wait (-1, status) =

 infrun: infwait_normal_state
 infrun: TARGET_WAITKIND_STOPPED
 infrun: stop_pc = 0x323d4ba7c4
 infrun: random signal 20
 infrun: stepi/nexti
 infrun: stop_stepping

So the inferior got a SIGCHLD (because the fork child exited while
we're doing 'si'), and since that signal is set to "nostop noprint
pass" (by default), it's considered a random signal, so it should not
cause a stop.  But, it resulted in an immediate a stop_stepping call
anyway.  So the single-step never really finished.

This is a regression caused by:

 [[PATCH] Do not respawn signals, take 2.]

part.  However, if we don't have a stepped thread to get back to,
we'll now also fall through to all the "stepping" tests.  For line
stepping, that'll turn out okay, as we'll just end up realizing the
thread is still in the stepping range, and needs to be re-stepped.
However, for stepi/nexti, we'll reach:

  if (ecs->event_thread->control.step_range_end == 1)
    {
      /* It is stepi or nexti.  We always want to stop stepping after

      ecs->event_thread->control.stop_step = 1;
      print_end_stepping_range_reason ();
      stop_stepping (ecs);
      return;
    }

and stop, even though the thread actually made no progress.  The fix
is to restore the keep_going call, but put it after the "switch back
to the stepped thread" code, and before the stepping tests.

fix for PR gdb/15995

This patch fixes PR gdb/15995.

The bug here is that gdb's printf command does not flush the output
stream.  This makes a printf that is not newline-terminated interleave
incorrectly with other forms of output, such as that generated via a
call to an external program using "shell".

I note that the "output" command already does this flushing.

The fix is to call gdb_flush in printf_command.

Built and regtested on x86-64 Fedora 18.
New test case included.

There were two functions who were calling "sizeof" twice.

The first one, dw2_get_real_path from gdb/dwarf2read.c, was actually
making use of OBSTACK_CALLOC which already calls "sizeof" for its third
argument.

The second, download_tracepoint_1 from gdb/gdbserver/tracepoint.c, was
explicitly calling "sizeof" inside another "sizeof".

This patch fixed both functions.

* tracepoint.c (download_tracepoint_1): Remove unnecessary double
call to sizeof.

This is a simple bug.  target_disable_btrace and target_teardown_btrace,
both from gdb/target.c, do a "return" calling another function.  But both
are marked as void.  Despite the fact that the functions being called are
void as well, this is wrong.  This patch fixes this by calling the functions
and then returning in the next line.

ChangeLog entries for the previous commit.

git-related mistake (added the files to the index, but forgot to
commit --amend them before pushing the commit)

Document the -catch-assert and -catch-exception new GDB/MI commands.

This patch adds documentation for the new GDB/MI commands "-catch-assert"
and "-catch-exception", meant to provide the same functionality as
the "catch assert", "catch exception" and "catch exception unhandled"
CLI commands.

In the GDB Manual, there was already a section for catchpoint comments,
so that seemed like a natural place to document the new commands. But
commands related to a given concept seem to have traditionally been
organized alphabetically, and I didn't want future commands to break
down logical pairing of various commands. For instance, "-catch-load"
and "-catch-unload" are quite "distant" from each other, and it is easy
to imagine a new comment which would alphabetically fall in between,
causing them to be separated. So I introduced subsections to prevent
that from happening.

gdb/ChangeLog:

        * NEWS: Add entry documenting the new "-catch-assert" and
        "-catch-exception" GDB/MI commands.

gdb/doc/ChangeLog:

        * gdb.texinfo (Shared Library GDB/MI Catchpoint Commands):
        New subsection inside which the "-catch-load" and "-catch-unload"
        commands documentation is now placed.
        (Ada Exception GDB/MI Catchpoint Commands): New subsection
        documenting the "-catch-assert" and "-catch-exception" new
        GDB/MI commands.

Adjust gdb.ada/mi_catch_ex.exp to use GDB/MI catch commands...

... in place of the CLI "catch ..." commands.  The latter were used
because the GDB/MI equivalents were not available at the time.

gdb/testsuite/ChangeLog:

        * gdb.ada/mi_catch_ex.exp: Adjusts all "catch ..." tests to
        use the appropriate GDB/MI command instead, and verify
        the test output.

New GDB/MI commands to catch Ada exceptions

This patch introduces two new GDB/MI commands implementing the equivalent
of the "catch exception" and  "catch assert" GDB/CLI commands.

gdb/ChangeLog:

        * breakpoint.h (init_ada_exception_breakpoint): Add parameter
        "enabled".

        ada-lang.c.
        (create_ada_exception_catchpoint): Add declaration.
        * ada-lang.c (ada_exception_catchpoint_kind): Move to ada-lang.h.
        (create_ada_exception_catchpoint): Make non-static. Add new
        parameter "disabled". Use it in call to
        init_ada_exception_breakpoint.
        (catch_ada_exception_command): Add parameter "enabled" in call
        to create_ada_exception_catchpoint.
        (catch_assert_command): Likewise.

        * mi/mi-cmds.h (mi_cmd_catch_assert, mi_cmd_catch_exception):
        Add declarations.
        * mi/mi-cmds.c (mi_cmds): Add the "catch-assert" and
        "catch-exception" commands.
        * mi/mi-cmd-catch.c: Add #include "ada-lang.h".
        (mi_cmd_catch_assert, mi_cmd_catch_exception): New functions.

Add "ada_" prefix to enum ada_exception_catchpoint_kind

This is in preparation for making that type public, in order to be
able to use make create_ada_exception_catchpoint public as well,
making it usable from the GDB/MI implementation.

gdb/ChangeLog:

        * ada-lang.c (enum ada_exception_catchpoint_kind): Renames
        "enum exception_catchpoint_kind".  Replace the "ex_" prefix
        of all its enumerates with "ada_".  Update the rest of this
        file throughout.

Rework a bit Ada exception catchpoint support (in prep for GDB/MI)

This patch reworks a bit how the different steps required to insert
an Ada exception catchpoints are organized. They used to be:

  1. Call a "decode" function which does:
        1.a.  Parse the command and its arguments
        1.b.  Create a SAL & OPS from some of those arguments

  2. Call create_ada_exception_catchpoint using SAL as well
     as some of the arguments extracted above.

The bulk of the change consists in integrating step (1.b) into
step (2) in order to turn create_ada_exception_catchpoint into
a function whose arguments are all user-level concepts. This
paves the way from a straightforward implementation of the equivalent
commands in the GDB/MI interpreter.

gdb/ChangeLog:

        * ada-lang.c (ada_decode_exception_location): Delete.
        (create_ada_exception_catchpoint): Remove arguments "sal",
        "addr_string" and "ops".  Add argument "ex_kind" instead.
        Adjust implementation accordingly, calling ada_exception_sal
        to get the entities it no longer gets passed as arguments.
        Document the function's arguments.
        (catch_ada_exception_command): Use catch_ada_exception_command_split
        instead of ada_decode_exception_location, and update call to
        create_ada_exception_catchpoint.
        (catch_ada_assert_command_split): Renames
        ada_decode_assert_location.  Remove parameters "addr_string" and
        "ops", and now returns void.  Adjust implementation accordingly.
        Update the function documentation.
        (catch_assert_command): Use catch_ada_assert_command_split
        instead of ada_decode_assert_location.  Update call to
        create_ada_exception_catchpoint.

Fix dates (wrong month) in the last 2 ChangeLog entries.

warn if "source" fails to open the file when from_tty == 0

Consider the following example:

    % gdb -q -batch -ex 'source nonexistant-file'
    [nothing]

One would have at least expected the debugger to warn about
not finding the file, similar to the error shown when using
a more interactive mode. Eg:

    (gdb) source nonexistant-file
    nonexistant-file: No such file or directory.

Not raising an error appears to be intentional, presumably in order
to prevent this situation from stoping the execution of a GDB script.
But the lack of at least a warning makes it harder for a user to
diagnose any issue, if the file was expected to be there and readable.

This patch adds a warning in that case:

    % gdb -q -batch -ex 'source nonexistant-file'
    warning: nonexistant-file: No such file or directory.

gdb/ChangeLog:

        * utils.h (perror_warning_with_name): Add declaration.
        * utils.c (perror_warning_with_name): New function.
        * cli/cli-cmds.c (source_script_with_search): Add call to
        perror_warning_with_name if from_tty is nul.

gdb/testsuite/ChangeLog:

        * gdb.base/source-nofile.gdb: New file.
        * gdb.base/source.exp: Add two tests verifying the behavior when
        the "source" command is given a non-existant filename.

new function perror_string extracted out of throw_perror_with_name.

The main purpose of this patch is to extract the part of
throw_perror_with_name that computes a string providing the system
error message combined with a prefix string.  This will become useful
later on to provide a routine which prints a warning using that
perror_string, rather than throwing an error.

gdb/ChangeLog:

        * utils.c (perror_string): New function, extracted out of
        throw_perror_with_name.
        (throw_perror_with_name): Rework to use perror_string.

gdb/testsuite/

[!__WIN32__]: Include "dlfcn.h".
* gdb.mi/mi-catch-load.exp: Set up kfail.

 * Removed short_hand field from opcode table and

Rename "set/show remotebaud" command into "set/show serial baud"

This patch renames the "set/show remotebaud" commands into
"set/show serial baud", and moves its implementation into serial.c.
It also moves the "baud_rate" global from top.c to serial.c, where
the new code is being added (the alternative was to add an include
of target.h).

And to facilitate the transition to the new setting name, this
patch also preserves the old commands, and marks them as deprecated
to alert the users of the change.

gdb/ChangeLog:

        * cli/cli-cmds.c (show_baud_rate): Moved to serial.c as
        serial_baud_show_cmd.
        (_initialize_cli_cmds): Delete the code creating the
        "set/show remotebaud" commands.
        * serial.c (baud_rate): Move here from top.c.
        (serial_baud_show_cmd): Move here from cli/cli-cmds.c.
        (_initialize_serial): Create "set/show serial baud" commands.
        Add "set/show remotebaud" command aliases.
        * top.c (baud_rate): Moved to serial.c.
        * NEWS: Document the new "set/show serial baud" commands,
        replacing "set/show remotebaud".

gdb/doc/ChangeLog:

        * gdb.texinfo: Replace "set remotebaud" and "show remotebaud"
        by "set serial baud" and "show serial baud" (resp) throughout.
