Christian Biesinger 39ef2f6256 Replace some more qsort calls with std::sort 
This has better typesafety, avoids a function pointer indirection,
and can benefit from inlining.

Simon Marchi 073bbbb058 gdb: small cleanup in breakpoint.c's includes 
In an attempt to reduce the number of files re-build when some headers
are touched, I ran include-what-you-use with breakpoint.c as a guinea
pig.  It revealed a few files that were unnecessary to include, which
this patch removes.

breakpoint.c uses tilde_expand from readline, hence the necessity to
include tilde.h.  AFAIK, it's fine to include just that, and not the
whole readline headers.

include-what-you-use also reported many header files that should be
included but aren't, I suppose that breakpoint.c currently includes them
indirectly.  For now I'll pretend I didn't see that :).

gdb/ChangeLog:

	* breakpoint.c: Remove some includes: continuations.h, skip.h,
	mi/mi-main.h, readline/readline.h, readline/history.h.  Add
	include: readline/tilde.h.

Tom Tromey 7f6aba03b9 Introduce metadata style 
This introduces a new "metadata" style and changes many places in gdb
to use it.  The idea here is to let the user distinguish gdb output
from output that (conceptually at least) comes directly from the
inferior.  The newly-styled category includes text that gdb
traditionally surrounds in "<...>", like "<unavailable>".

I only added a single test for this.  In many cases this output is
difficult to test.  Also, while developing this errors in the
implementation of the new printf formats showed up as regressions.

Philippe Waroquiers 590042fc45 Make first and last lines of 'command help documentation' consistent. 
With this patch, the help docs now respect 2 invariants:
  * The first line of a command help is terminated by a '.' character.
  * The last character of a command help is not a newline character.

Note that the changes for the last invariant were done by Tom, as part of :
 [PATCH] Remove trailing newlines from help text
 https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.

Some help docs had to be rephrased/restructured to respect the above
invariants.

Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.

This was giving inconsistent results :
  * The first line of command helps was sometimes '.' terminated,
    sometimes not.
  * The first line of command helps was not always designed to be
    readable/understandable/unambiguous when stopping at the first
    '.' or ',' character.

This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.

Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.

This patch changes the help documentations to ensure the 2 invariants
given above.

It implied to slightly rephrase or restructure some help docs.

Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.

This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

Pedro Alves a38118e5d1 Make "maint info breakpoints" show "catch catch/throw/rethrow" locations 
This commit makes "maint info breakpoints" show the internal locations
of C++ exception catchpoints:

 (gdb) info breakpoints
 Num     Type           Disp Enb Address            What
 2       catchpoint     keep y                      exception catch

With multiple locations:

 (gdb) maint info breakpoints
 Num     Type           Disp Enb Address            What
 2       catchpoint     keep y                      exception catch
 2.1                         y   0x000000000040545f <__cxa_begin_catch+95> inf 1
 2.2                         y   0x00007ffff71dbe0f <__cxxabiv1::__cxa_begin_catch(void*)+95> inf 1
 (gdb)

With a single location:

 (gdb) maint info breakpoints 2
 Num     Type           Disp Enb Address            What
 2       catchpoint     keep y                      exception catch inf 1
 2.1                         y   0x00007ffff7bc0b7f <__cxa_begin_catch+95> inf 1

With no locations:

 (gdb) maint info breakpoints 2
 Num     Type           Disp Enb Address            What
 2       catchpoint     keep y                      exception catch inf 1


Other catchpoints still show the same way, here a catch signal:

 (gdb) info breakpoints
 Num     Type           Disp Enb Address            What
 3       catchpoint     keep y                      signal "<standard signals>"

 (gdb) maint info breakpoints
 Num     Type           Disp Enb Address            What
 3       catchpoint     keep y                      signal "<standard signals>"  inf 1
 (gdb)

Note: I considered making the locations be printed from within
breakpoint_ops::print_one(), but gave up given the handling for the
broken MI v2 output:

 /* The mi2 broken format: the main breakpoint tuple ends here, the locations
     are outside.  */
  if (!use_fixed_output)
    bkpt_tuple_emitter.reset ();

in print_one_breakpoint.

Pedro Alves cb1e4e32c2 "catch catch/throw/rethrow", breakpoint -> catchpoint 
Currently, with:

 (gdb) catch catch
 Catchpoint 1 (catch)
 (gdb) catch throw
 Catchpoint 2 (throw)
 (gdb) catch rethrow
 Catchpoint 3 (rethrow)

You get:

(gdb) info breakpoints
 Num     Type           Disp Enb Address            What
 1       breakpoint     keep y   0x0000000000b122af exception catch
 2       breakpoint     keep y   0x0000000000b1288d exception throw
 3       breakpoint     keep y   0x0000000000b12931 exception rethrow

I think it doesn't make much sense usability-wise, to show a
catchpoint as a breakpoint.  The fact that GDB sets a breakpoint at
some magic address in the C++ run time is an implementation detail,
IMO.  And as seen in the previous patch, such a catchpoint can end up
with more than one location/address even, so showing a single address
isn't entirely accurate.

This commit hides the addresses from view, and makes GDB show
"catchpoint" for type as well:

  (gdb) info breakpoints
  Num     Type           Disp Enb Address            What
  1       catchpoint     keep y                      exception catch
  2       catchpoint     keep y                      exception throw
  3       catchpoint     keep y                      exception rethrow

This comment in the code seems telling:

  /* We need to reset 'type' in order for code in breakpoint.c to do
     the right thing.  */
  cp->type = bp_breakpoint;

It kind of suggests that the reason catchpoints end up shown as
breakpoints was that it was easier to implement them that way, rather
than a desired property.

This commit fixes things up to make it possible to have bp_catch
breakpoints have software/hardware breakpoint locations, thus
eliminating the need for that hack:

 - redo breakpoint_address_is_meaningful in terms of the location's
   type rather than breakpoint type.
 - teach bpstat_what about stepping over the catchpoint locations.
 - install a allocate_location method for "catch catch/throw/rethrow",
   one that forces the location type.

Note that this also reverts the gdb hunk from:

  commit 2a8be20359
  Commit:     Tom Tromey <tom@tromey.com>
  CommitDate: Sat Oct 6 22:17:45 2018 -0600

      Fix Python gdb.Breakpoint.location crash

because now "catch throw" catchpoints hit the

   if (obj->bp->type != bp_breakpoint)
     Py_RETURN_NONE;

check above, and, adjusts the testcase to no longer expect to see the
catchpoint in the gdb.breakpoints() list.

(Note: might make sense to do the same to Ada exception catchpoints.)

Pedro Alves b58a68fe57 Fix "info break" + "catch catch" + -static-{libstdc++,libgcc} 
If you debug current GDB, set a "catch catch/throw/rethrow"
catchpoint, and then do "info breakpoints", the top GDB hits an
internal error:

 (top-gdb) catch catch
 Catchpoint 1 (catch)
 (top-gdb) info breakpoints
 Num     Type           Disp Enb Address            What
 1       breakpoint     keep y   src/gdb/breakpoint.c:6040: internal-error: void print_one_breakpoint_location(breakpoint*, bp_location*, int, bp_location**, int): Assertion `b->loc == NULL || b->loc->next == NULL' failed.
 A problem internal to GDB has been detected,
 further debugging may prove unreliable.
 Quit this debugging session? (y or n)

The assertion in question is asserting that a breakpoint with a
print_one method only has one location, and it fails because this
catchpoint ends up with two locations.

Internally, "catch catch" sets a breakpoint at __cxa_begin_catch.  If
we do that manually, we see the locations:

  (top-gdb) b -qualified __cxa_begin_catch
  Breakpoint 2 at 0xb122b0 (2 locations)
  (top-gdb) info breakpoints
  Num     Type           Disp Enb Address            What
  2       breakpoint     keep y   <MULTIPLE>
  2.1                         y   0x0000000000b122b0 <__cxa_begin_catch>
  2.2                         y   0x00007ffff2f4ddb0 in __cxxabiv1::__cxa_begin_catch(void*) at ../../../../libstdc++-v3/libsupc++/eh_catch.cc:41

Note that I had used -qualified.  It seems strange that we get a
location for a namespaced symbol, but that happens because the minimal
symbol for that address is indeed called __cxa_begin_catch.

The real issue is that gdb is linked with
-static-libgcc/-static-libstdc++.  And then, it _also_ ends up with
shared libstc++ loaded:

  (top-gdb) info sharedlibrary stdc++
  From                To                  Syms Read   Shared Object Library
  0x00007ffff2f4b380  0x00007ffff2ffc018  Yes         /lib64/libstdc++.so.6

Location 2.2 is set within libstdc++.so.6's range:

  (top-gdb) p 0x00007ffff2f4b380 <= 0x00007ffff2f4ddb0 && 0x00007ffff2f4ddb0 < 0x00007ffff2ffc018
  $1 = true

So due to -static-lib*, we end up with _two_ copies of the
__cxa_begin_catch code:

  (top-gdb) disassemble 0x0000000000b122b0
  Dump of assembler code for function __cxa_begin_catch:
     0x0000000000b122b0 <+0>:     push   %rbx
     0x0000000000b122b1 <+1>:     mov    %rdi,%rbx
     0x0000000000b122b4 <+4>:     callq  0xb11a80 <__cxa_get_globals>
     0x0000000000b122b9 <+9>:     movabs $0xb8b1aabcbcd4d500,%rdx
  ...

  (top-gdb) disassemble 0x00007ffff2f4ddb0
  Dump of assembler code for function __cxxabiv1::__cxa_begin_catch(void*):
     0x00007ffff2f4ddb0 <+0>:     push   %rbx
     0x00007ffff2f4ddb1 <+1>:     mov    %rdi,%rbx
     0x00007ffff2f4ddb4 <+4>:     callq  0x7ffff2f4a090 <__cxa_get_globals@plt>
     0x00007ffff2f4ddb9 <+9>:     movabs $0xb8b1aabcbcd4d500,%rdx
  ...

I think we end up with libstdc++.so.6 loaded because
libsource-highlight.so depends on it.

Irrespective of whether it's a good idea to use
-static-libgcc/-static-libstdc++, GDB should not crash.  Since there
are two copies of the code, it seems right to have more than one
location.  So the fix is just to remove the assertion.

A testcase is included, which mimics the scenerio described above,
with binary linked with -static-lib{stdc++,gcc} and a shared library
that is linked normally, along with other combinations for good
measure.

Tom Tromey 268a13a5a3 Rename common to gdbsupport 
This is the next patch in the ongoing series to move gdbsever to the
top level.

This patch just renames the "common" directory.  The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top.  This approach makes the patches a bit
more tractable.

I chose the name "gdbsupport" for the directory.  However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

Tested by the buildbot.

Andrew Burgess 0ba852ab41 gdb: Remove unneeded parameter from set_breakpoint_location_function 
The explicit_loc parameter in set_breakpoint_location_function is not
useful.  This parameter is set from two possible fields of the
symtab_and_line used to create the breakpoint; the explicit_pc field,
and the explicit_line field.

First, the explicit_line field, this is not currently set for any
breakpoint command, so will never be true.

Next, the explicit_pc field.  This can be true but will never be true
at the same time that the sal->msymbol field is also true - the
sal->msymbol is only ever set in linespec.c:minsym_found, which
doesn't allow for explicitly setting the pc.

The result of this is that if we are setting a breakpoint on an
msymbol that could turn out to be an ifunc, then we will not also have
either an explicit_pc or an explicit_line, this check can therefore be
removed.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* breakpoint.c (set_breakpoint_location_function): Remove
	explicit_loc parameter.
	(momentary_breakpoint_from_master): Update call to
	set_breakpoint_location_function.
	(add_location_to_breakpoint): Likewise.

Tom Tromey cafb34387d Remove unnecessary casts of NULL 
I noticed some unnecessary casts of NULL.  This removes all the

Andrew Burgess 30056ea04a gdb/mi: New commands to catch C++ exceptions 
Adds some MI commands to catch C++ exceptions.  The new commands are
-catch-throw, -catch-rethrow, and -catch-catch, these all correspond
to the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'.

Each MI command takes two optional arguments, '-t' has the effect of
calling 'tcatch' instead of 'catch', for example:

   (gdb)
   -catch-throw -t

Is the same as:

   (gdb) tcatch throw

There is also a '-r REGEXP' argument that can supply a regexp to match
against the exception type, so:

   (gdb)
   -catch-catch -r PATTERN

Is the same as:

   (gdb) catch catch PATTERN

The change in print_mention_exception_catchpoint might seem a little
strange; changing the output from using ui_out::field_int and
ui_out::text to using  ui_out::message.

The print_mention_exception_catchpoint is used as the 'print_mention'
method for the exception catchpoint breakpoint object.  Most of the
other 'print_mention' methods (see breakpoint.c) use either
printf_filtered, of ui_out::message.  Using field_int was causing an
unexpected field to be added to the MI output.  Here's the output
without the change in print_mention_exception_catchpoint:

    (gdb)
    -catch-throw
    ^done,bkptno="1",bkpt={number="1",type="breakpoint",disp="keep",
                           enabled="y",addr="0x00000000004006c0",
                           what="exception throw",catch-type="throw",
                           thread-groups=["i1"],times="0"}

Notice the breakpoint number appears in both the 'bkptno' field, and
the 'number' field within the 'bkpt' tuple.  Here's the output with
the change in print_mention_exception_catchpoint:

    (gdb)
    -catch-throw
    ^done,bkpt={number="1",type="breakpoint",disp="keep",
                enabled="y",addr="0x00000000004006c0",
                what="exception throw",catch-type="throw",

Tom Tromey 89549d7f4d Remove trailing newlines from help text 
I noticed recently that some command had a trailing newline in its
"help" output.  So, I temporarily hacked cli-decode.c to print
something when a new command was installed that had a trailing newline
in its help message, and wrote this patch, which removes all the ones
I could find this way.  (There could still be a few more in *-nat
files.)

Tested on x86-64 Fedora 29.

Pedro Alves b02f78f928 Introduce and use make_unique_xstrdup 
Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.

Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet.  I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

Simon Marchi 1367480341 Fix GDB build when using --disable-gdbmi 
Since commit

    b4be1b0648 ("Fix MI output for multi-location breakpoints")

we get this error when building with --disable-gdbmi:

      CXXLD  gdb
    /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)'

This is due to breakpoint.c using a function defined in mi/mi-main.c, even
though mi/mi-main.c isn't included in the build.

To fix it, use the flags feature of ui_out.  mi_ui_out has the new
fix_multi_location_breakpoint_output flag set for versions >= 3.  Also,
move the global variable fix_multi_location_breakpoint_output to
breakpoint.c, so it can be read there even when we build without MI.  I
renamed it to fix_multi_location_breakpoint_output_globally so it
doesn't clash with the new enumerator.

gdb/ChangeLog:

	* breakpoint.h (fix_multi_location_breakpoint_output_globally):
	New variable declaration.
	* breakpoint.c (fix_multi_location_breakpoint_output_globally):

	(print_one_breakpoint): Use ui_out::test_flags and new global
	variable to compute use_fixed_output.

	(mi_multi_location_breakpoint_output_fixed): Remove.
	(mi_cmd_fix_multi_location_breakpoint_output): Adjust to set the
	new variable.
	* mi/mi-out.c (mi_ui_out::mi_ui_out): Set
	fix_multi_location_breakpoint_output flag if version >= 3.
	* ui-out.h (enum ui_out_flag)
	<fix_multi_location_breakpoint_output>: New enumerator.

Tom Tromey eedc3f4f0a Replace throw_exception with throw in some cases 
This replaces throw_exception with "throw;" when possible.  This was
written by script.  The rule that is followed is that uses of the
form:

   catch (... &name)
     {
       ...
       throw_exception (name);
     }

... can be rewritten.  This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.

Tom Tromey a70b814420 Rewrite TRY/CATCH 
This rewrites gdb's TRY/CATCH to plain C++ try/catch.  The patch was
largely written by script, though one change (to a comment in
common-exceptions.h) was reverted by hand.

Tom Tromey 3d6e9d2336 Make exceptions use std::string and be self-managing 
This changes the exception's "message" member to be a shared_ptr
wrapping a std::string.  This allows removing the stack of exception
messages, because now exceptions will self-destruct when needed.  This
also adds a noexcept copy constructor and operator= to gdb_exception,
plus a "what" method.

Tom Tromey 4de283e4b5 Revert the header-sorting patch 
Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).

So, I'm reverting the patch.  I may try again after fixing the issues
pointed out.

This patch sorts the include files for the files [a-f]*.[chyl].
The patch was written by a script.

Tested by the buildbot.

I will follow up with patches to sort the remaining files, by sorting
a subset, testing them, and then checking them in.

Tom Tromey 699bd4cfa8 Move innermost_block_tracker global to parse_state 
This changes the parsing API so that callers that are interested in
tracking the innermost block must instantiate an

Tom Tromey 7ad417dd21 Have parser reset the innermost block tracker 
I ran across a comment in symfile.c today:

  /* Clear globals which might have pointed into a removed objfile.
     FIXME: It's not clear which of these are supposed to persist
     between expressions and which ought to be reset each time.  */

It seems to me that this can be clarified: the parser entry points
ought to reset the innermost block tracker (and the expression context
block), and these should not be considered valid for code to use at
arbitrary times -- only immediately after an expression has been
parsed.

This patch implements this idea.  This could be further improved by
removing the parser globals and changing the parser functions to
return this information, but I have not done this.

Tested by the buildbot.

Simon Marchi b4be1b0648 Fix MI output for multi-location breakpoints 
New in v2:

- Addressed comments about doc, updated the MI version table
- New doc for the Breakpoint information format
- New -fix-multi-location-breakpoint-output command, with associated
  doc, test and NEWS updated accordingly
- Fixed the output, the locations list is now actually in the tuple
  representing the breakpoint.

Various MI commands or events related to breakpoints output invalid MI
records when printing information about a multi-location breakpoint.
For example:

    -break-insert allo
    ^done,bkpt={...,addr="<MULTIPLE>",...},{number="1.1",...},{number="1.2",...}

The problem is that according to the syntax [1], the top-level elements
are of type "result" and should be of the form "variable=value".

This patch changes the output to wrap the locations in a list:

    ^done,bkpt={...,addr="<MULTIPLE>",locations=[{number="1.1",...},{number="1.2",...}]}

The events =breakpoint-created, =breakpoint-modified, as well as the
-break-info command also suffer from this (and maybe others I didn't
find).

Since this is a breaking change for MI, we have to deal somehow with
backwards compatibility.  The approach taken by this patch is to bump
the MI version, use the new syntax in MI3 while retaining the old syntax
in MI2.  Frontends are expected to use a precise MI version (-i=mi2), so
if they do that they should be unaffected.

The patch also adds the command -fix-multi-location-breakpoint-output,
which front ends can use to enable this behavior with MI <= 2.

[1] https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI-Output-Syntax.html#GDB_002fMI-Output-Syntax

gdb/ChangeLog:

	* NEWS: Mention that the new default MI version is 3.  Mention
	changes to the output of commands and events that deal with
	multi-location breakpoints.
	* breakpoint.c: Include "mi/mi-out.h".

Tom Tromey 5f48666010 C++-ify bp_location 
Philippe noticed a memory leak coming from ada_catchpoint_location --
it was not freeing the "function_name" member from its base class:

This patch fixes the problem by further C++-ifying bp_location.  In
particular, bp_location_ops is now removed, and the "dtor" function
pointer is replaced with an ordinary destructor.
