f2fc30156c Constify some linespec functions
This changes a few linespec functions to work on "const char *" and
then fixes up all the callers.  This allows further constification
elsewhere.

0450cc4ce8 Add add_cmd function overloads
This adds two add_cmd overloads: one whose callback takes a const char *,
and one that doesn't accept a function at all.  The no-function overload
was introduced to avoid ambiguity when NULL was passed as the function.

Long term the goal is for all commands to take const arguments, and
for the non-const variants to be removed entirely.

43573013c9 Get rid of "gdb_dirbuf" and use "getcwd (NULL, 0)"
Currently we have "current_directory" and "gdb_dirbuf" globals, which
means that we basically have two possible places to consult when we
want to know GDB's current working directory.

This is not ideal and can lead to confusion.  Moreover, the way we're
using "gdb_difbuf" along with "getcwd" is problematic because we
declare the buffer with "1024" elements hardcoded, which does not take
into account longer pathnames that are possible in many filesystems.
Using "PATH_MAX" would also not be a solution because of portability
problems.  Therefore, the best solution is to rely on the fact that
"getcwd (NULL, 0)" will "do the right thing" and return a
heap-allocated string containing the full path.  With the new "getcwd"
module from gnulib, it is now possible to do that without worrying
about breaking some host.

With this patch "current_directory" is now the only place to check for
GDB's cwd.

06871ae840 Make "list ambiguous" show symbol names too
Currently, with an ambiguous "list first,last", we get:

  (gdb) list bar,main
  Specified first line 'bar' is ambiguous:
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98

This commit makes gdb's output above a bit clearer by printing the
symbol name as well:

  (gdb) list bar,main
  Specified first line 'bar' is ambiguous:
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97, symbol: "bar(A)"
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98, symbol: "bar(B)"

And while at it, makes gdb print the symbol name when actually listing
multiple locations too.  I.e., before (with "set listsize 2"):

  (gdb) list bar
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97
  96
  97      int bar (A) { return 11; }
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98
  97      int bar (A) { return 11; }
  98      int bar (B) { return 22; }

After:

  (gdb) list bar
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97, symbol: "bar(A)"
  96
  97      int bar (A) { return 11; }
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98, symbol: "bar(B)"
  97      int bar (A) { return 11; }
  98      int bar (B) { return 22; }

Currently, the result of decoding a linespec loses information about
the original symbol that was found.  All we end up with is an address.
This makes it difficult to find the original symbol again to get at
its print name.  Fix that by storing a pointer to the symbol in the
sal.  We already store the symtab and obj_section, so it feels like a
natural progression to me.  This avoids having to do any extra symbol
lookup too.

f1735a53a6 Rename _const functions to use overloading instead
This renames a few functions -- skip_spaces_const,
skip_to_space_const, get_number_const, extract_arg_const -- to drop
the "_const" suffix and instead rely on overloading.

This makes future const fixes simpler by reducing the number of lines
that must be changed.  I think it is also not any less clear, as all
these functions have the same interface as their non-const versions by
design.  Furthermore there's an example of using an overload in-tree
already, namely check_for_argument.

This patch was largely created using some perl one-liners; then a few
fixes were applied by hand.

9a24775b97 Introduce gdb_disassembly_flags
For some reason I ended up staring at some of the "int flags" in
btrace-related code, and I got confused because I had no clue what the
flags where supposed to indicate.

Fix that by using enum_flags, so that:
  #1 - it's clear from the type what the flags are about, and
  #2 - the compiler can catch mismatching mistakes

51abb42130 Kill init_sal
Instead, make symtab_and_line initialize its members itself.  Many
symtab_and_line declarations are moved to where the object is
initialized at the same time both for clarity and to avoid double
initialization.  A few functions, like e.g., find_frame_sal are
adjusted to return the sal using normal function return instead of an
output parameter likewise to avoid having to default-construct a sal
and then immediately have the object overwritten.

6c5b2ebeac struct symtabs_and_lines -> std::vector<symtab_and_line>
This replaces "struct symtabs_and_lines" with
std::vector<symtab_and_line> in most cases.  This removes a number of
cleanups.

In some cases, the sals objects do not own the sals they point at.
Instead they point at some sal that lives on the stack.  Typically
something like this:

  struct symtab_and_line sal;
  struct symtabs_and_lines sals;

  // fill in sal

  sals.nelts = 1;
  sals.sals = &sal;

  // use sals

Instead of switching those cases to std::vector too, such usages are
replaced by gdb::array_view<symtab_and_line> instead.  This avoids
introducing heap allocations.

e439fa140a Clarify "list" output when specified lines are ambiguous
Currently, with "list LINESPEC1,LINESPEC2", if one of the linespecs is
ambiguous, i.e., if it expands to multiple locations, you get this
seemingly odd output:

 (gdb) list foo,bar
 file: "file0.c", line number: 26
 file: "file1.c", line number: 29

Since "foo" above expands to multiple locations, the specified range
is indeterminate, and GDB is trying to be helpful by showing you what
was ambiguous.  It looks confusing to me, though.  I think it'd be
much more user friendly if GDB actually told you that, like this:

 (gdb) list foo,bar
 Specified first line 'foo' is ambiguous:
 file: "file0.c", line number: 26
 file: "file1.c", line number: 29

 (gdb) list bar,foo
 Specified last line 'foo' is ambiguous:
 file: "file0.c", line number: 26
 file: "file1.c", line number: 29

Note, I'm using "first" and "last" in the output because that's what
the manual uses:

 ~~~
 list first,last

     Print lines from first to last. [...]
 ~~~

Tested on x86-64 GNU/Linux.

0d999a6ef0 List actual code around more than one location
With the following C++ code:
 int bar() { return 0;}
 int bar(int) { return 0; }

GDB behaves as:
 (gdb) list bar
  file: "overload.cc", line number: 1
  file: "overload.cc", line number: 2

It would be better for GDB to list the actual code around those two
locations, not just print the location.  Like:

 (gdb) list bar
 file: "overload.cc", line number: 1
 1       int bar() { return 0;}
 2       int bar(int) { return 0; }
 file: "overload.cc", line number: 2
 1       int bar() { return 0;}
 2       int bar(int) { return 0; }

That's what this this commit implements.

c6756f62e0 Rewrite/enhance explicit locations completer, parse left->right
One of the most annoying (to me) things about GDB's completion is when
you have overloads in your program, and you want to set a breakpoint
in one of them:

 void function(int);  // set breakpoint here.
 void function(long);

 (gdb) b -f func[TAB]
 (gdb) b -f function(       # ok, gdb completed as much as possible.
 (gdb) b -f function([TAB]  # show me the overloads, please.
 <_all_ symbols in the program are shown...>

E.g., when debugging GDB, that'd be:

 (gdb) b -f function([TAB]
 (anonymous namespace)::get_global()::global  pt_insn_get_offset@plt                       scm_new_port_table_entry
 asprintf                                     pt_pkt_alloc_decoder                         scm_new_port_table_entry@plt
 asprintf@plt                                 pt_pkt_alloc_decoder@plt                     scm_out_of_range
 bt_ctf_get_char_array                        pt_pkt_sync_forward                          scm_out_of_range@plt
 bt_ctf_get_char_array@plt                    pt_pkt_sync_forward@plt                      scm_putc
 bt_ctf_get_uint64                            pwrite                                       scm_putc@plt
 bt_ctf_get_uint64@plt                        pwrite@plt                                   scm_reverse_x
 bt_ctf_iter_read_event                       PyErr_Restore                                scm_reverse_x@plt
 bt_ctf_iter_read_event@plt                   PyErr_Restore@plt                            scm_set_port_filename_x
 <snip...>

Now that's a load of completely useless completions.

The reason GDB offers those is that the completer relies on readline
figuring out the completion word point in the input line based on the
language's word break characters, which include "(".  So readline
tells the completer to complete on "", the string that is after '('.
Likewise, if you type "function(i[TAB]" to try to complete to "int",
you're out of luck.  GDB shows you all the symbols in the program that
start with "i"...  This makes sense for the expression completer, as
what you'd want to type is e.g., a global variable, say:

(gdb) print function(i[TAB]

but, it makes no sense when specifying a function name for a
breakpoint location.

To get around that limitation, users need to quote the function name,
like:

 (gdb) b -f 'function([TAB]
 function(int)      function(long)
 (gdb) b 'function(i[TAB]
 (gdb) b 'function(int)' # now completes correctly!

Note that the quoting is only necessary for completion.  Creating the
breakpoint does not require the quoting:

 (gdb) b -f function(int) [RET]
 Breakpoint 1 at ....

This patch removes this limitation.

(
Actually, it's a necessary patch, though not sufficient.  That'll
start working correctly by the end of the series.  With this patch, if try it,
you'll see:

 (gdb) b -f function(i[TAB]
 (gdb) b -f function

i.e., gdb strips everything after the "(".  That's caused by some code
in symtab.c that'll be eliminated further down the series.  These
patches are all unfortunately interrelated, which is also the reason
new tests only appear much later in the series.
But let's ignore that reality for the remainder of the description.
)

So... this patch gets rid of the need for quoting.

It does that by adding a way for a completer to control the exact
completion word point that readline should start the completion
request for, instead of letting readline try to figure it out using
the current language's word break chars array, and often failing.

In the case above, we want the completer to figure out that it's
completing a function name that starts with "function(i".  It now
does.

It took me a while to figure out a way to ask readline to "use this
exact word point", and for a while I feared that it'd be impossible
with current readline (and having to rely on master readline for core
functionality is something I'd like to avoid very much).  Eventually,
after several different attempts, I came up with what is described in
the comment above gdb_custom_word_point_brkchars in the patch.

With this patch, the handle_brkchars phase of the explicit location
completer advances the expected word point as it parses the input line
left to right, until it figures out exactly what we're completing,
instead of expecting readline to break the string using the word break
characters, and then having the completer heuristically fix up a bad
decision by parsing the input string backwards.  This allows correctly
knowning that we're completing a symbol name after -function, complete
functions without quoting, etc.

Later, we'll make use of this same mechanims to implement a proper
linespec completer that avoids need for quoting too.

6a2c1b8790 "complete" command and completion word break characters
The linespec/locations/completer testcase added later in the series
tests every completion with both TAB completion and the "complete"
command.  This exposed problems in the "complete" command, around
determining the completion word point.

First, the complete command has a too-simple approximation of what
readline's TAB-completion code does to find the completion word point.
Unfortunately, readline doesn't expose the functionality it uses
internally, so to fix this this patch copies over the relevant code,
and adjusts it a bit to better fit the use cases we need it for.
(Specifically, our version avoids relying on the
rl_word_break_characters, etc. globals, and instead takes those as
arguments.)

A following patch will want to use this function for TAB-completion
too, but the "complete" command was a good excuse to split this to a
separate patch.

Then, notice how the complete_command does not call into the completer
for the command being completed to determine the right set of word
break characters.  It always uses the default set.  That is fixed by
having the "complete" command call into complete_line_internal for a
full handle_brkchars phase, just TAB-completion.

eb3ff9a551 Introduce class completion_tracker & rewrite completion<->readline interaction
This patch reworks the whole completion machinery, and prepares it
for later enhancements.

Adds a new "completion_tracker" class that is meant to hold everything
about the state of the current completion operation.

This class now has the responsibility of tracking the list of
completion matches, and checking whether the max completions limit has
been reached.  You can look at this as this patch starting out by
C++fying the existing "completion_tracker" in symtab.c (it's just an
htab_t typedef currently), moving it to completer.h/c, and then making
it a class/generalizing/enhancing it.

Unlike with the current tracking, completion_tracker now checks
whether the limit has been reached on each completion match list
insertion.  This both simplifies the max-completions handling code
(maybe_add_completion_enum is gone, for example), and is a
prerequisite for follow up patches.

The current completion_tracker is only used for symbol completions,
and the symbol code gets at the current instance via globals.  This
patch cleans that up by adding a completion_tracker reference to the
signature of the completion functions, and passing the tracker around
everywhere necessary.

Then, the patch changes how the completion match list is handed over
to readline.  Currently, we're using the rl_completion_entry_function
readline entry point, and the patch switches to
rl_attempted_completion_function.  A following patch will want to let
GDB itself decide the common completion prefix between all matches
(what readline calls the "lowest common denominator"), instead of
having readline compute it, and that's not possible with the
rl_completion_entry_function entry point.  Also,
rl_attempted_completion_function lets GDB hand over the match list to
readline as an array in one go instead of passing down matches one by
one, so from that angle it's a nicer entry point anyway.

Lastly, the patch catches exceptions around the readline entry points,
because we can't let C++ exceptions cross readline.  We handle that in
the readline input entry point, but the completion entry point isn't
guarded, so GDB can abort if completion throws.  E.g., in current
master:

 (gdb) b -function "fun<tab>
 terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'
 Aborted (core dumped)

This patch fixes that.  This will be exercised in the new tests added
later on in the series.

ffc2605c41 Introduce event_location_up
This removes make_cleanup_delete_event_location and instead changes
the various location functions to return an event_location_up, a new
unique_ptr typedef.

This is largely straightforward, but be sure to examine the
init_breakpoint_sal change.  I believe the code I deleted there is
dead, because "location != NULL" can never be true in that branch; but
you should double-check.

112e8700a6 Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy.  ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.

In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.

It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

36cf1806a8 PR gdb/20604 - fix "quit" when an invalid expression is used
This fixes PR gdb/20604.  The bug here is that passing an invalid
expression to "quit" -- e.g., "quit()" -- causes gdb to enter a
non-functioning state.

The immediate problem is that quit_force resets the terminal before
evaluating the expression.  However, it seemed to me that it doesn't
really make sense to pass the quit_force argument to kill_or_detach
(which passes it to to_detach), first because conflating the exit
status for "quit" and the signal to pass when detaching doesn't make
sense, and second because to_detach implementations generally only
accept a constant here, while "quit" accepts an expression.  So, I
removed that.

As an aside, I think the "detach SIGNO" functionality is not
documented.

Built and regtested on x86-64 Fedora 24.

c2f4122d5c Limit breakpoint re-set to the current program space
Currently, we always re-set all locations of all breakpoints.  This
commit makes us re-set only locations of the current program space.

If we loaded symbols to a program space (e.g., "file" command or some
shared library was loaded), GDB must run through all breakpoints and
determine if any new locations need to be added to the breakpoint.
However, there's no reason to recreate locations for _other_ program
spaces, as those haven't changed.

Similarly, when we create a new inferior, through e.g., a fork, GDB
must run through all breakpoints and determine if any new locations
need to be added to the breakpoint.  There's no reason to destroy the
locations of the parent inferior and other inferiors.  We know those
won't change.

In addition to being inneficient, resetting breakpoints of inferiors
that are currently running is problematic, because:

 - some targets can't read memory while the inferior is running.

 - the inferior might exit while we're re-setting its breakpoints,
   which may confuse prologue skipping.

I went through all the places where we call breakpoint_re_set, and it
seems to me that all can be changed to only re-set locations of the
current program space.

The patch that reversed threads order in "info threads" etc. happened
to make gdb.threads/fork-plus-thread.exp expose this problem when
testing on x86/-m32.  The problem was latent and masked out by chance
by the code-cache:

 https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html

Tested on x86-64 F20, native (-m64/-m32) and extended-remote
gdbserver.

Fixes the regression discussed in the url above with --target_board=unix/-m32:

 -FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
 +PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited

3b2464a8d3 gdb: Add an error when 'list -' reaches the start of a file.
When a a user uses 'list +' to list forward through a source file they
eventually reach the end of the source file.  Subsequent uses of 'list
+' result in an error message like this, that let the user know they are
at the end of the source file:

  Line number XXX out of range; FILENAME has YYY lines.

Compare this to the current behaviour of 'list -' which lists backwards
through a source file.  When the user reaches the beginning of the
source file, subsequent uses of 'list -' result in the command silently
returning.  This can be confusing if the previous uses of 'list -' have
scrolled off the users display, the user receives no reminder that the
have already seen the start of the file.

After this commit a use of 'list -' when the user has already seen the
start of a file will receive the following error:

   Already at the start of FILENAME.

	* cli/cli-cmds.c (list_command): Add an error when trying to use
	'-' to scan read off the start of the source file.

a0def019aa gdb: 'list' command, tweak handling of +/- arguments.
There is an inconsistency with the handling of the special +/- arguments
to the list command.

For the very first time that list is used (after the inferior has
changed locations) then only the first character of the argument string
is checked, so 'list +BLAH' will operate as 'list +' and 'list -----FOO'
will operate as 'list -'.  This compares to each subsequent use of list,
where the whole argument string is checked, so 'list +BLAH' will try to
list lines of code around the function '+BLAH'.

This commit unifies the behaviour so that the whole argument string is
checked, in order to list the next 10, or previous 10 lines from a file
only 'list +' and 'list -' are now valid.

gdb/ChangeLog:

	* cli/cli-cmds.c (list_command): Check that the argument string is

9a3c826307 Add some more casts (1/2)
Note: I needed to split this patch in two, otherwise it's too big for
the mailing list.

This patch adds explicit casts to situations where a void pointer is
assigned to a pointer to the "real" type.  Building in C++ mode requires
those assignments to use an explicit cast.  This includes, for example:

 - callback arguments (cleanups, comparison functions, ...)
 - data attached to some object (objfile, program space, etc) in the form
   of a void pointer
 - "user data" passed to some function

This patch comes from the commit "(mostly) auto-generated patch to insert
casts needed for C++", taken from Pedro's C++ branch.

Only files built on x86 with --enable-targets=all are modified, so the
native files for other arches will need to be dealt with separately.

I built-tested this with --enable-targets=all and reg-tested.  To my
surprise, a test case (selftest.exp) had to be adjusted.

Here's the ChangeLog entry.  Again, this was relatively quick to make
despite the length, thanks to David Malcom's script, although I don't
believe it's very useful information in that particular case...

224c3ddb89 Add casts to memory allocation related calls
Most allocation functions (if not all) return a void* pointing to the
allocated memory.  In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).

The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++".  I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style.  I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.

Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.

Only files built on x86 with --enable-targets=all are modified.  This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers.  Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.

I built-tested this with --enable-targets=all and reg-tested.

Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script.  I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

8d7493201c Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort.  The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family.  This avoids adding an explicit cast, so
it keeps the code a bit more readable.  Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.

I only changed calls that were obviously allocating memory for one or
multiple "objects".  Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).

  - xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
  - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
  - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
  - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
  - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
  - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
  - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
  - alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
  - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)

Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.

I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files.  For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

6ff0ba5f7b New /s modifier for the disassemble command.
The "source centric" /m option to the disassemble command is often
unhelpful, e.g., in the presence of optimized code.
This patch adds a /s modifier that is better.
For one, /m only prints instructions from the originating source file,
leaving out instructions from e.g., inlined functions from other files.

	PR gdb/11833
	* NEWS: Document new /s modifier for the disassemble command.

f00aae0f7b Explicit locations: use new location API
This patch converts the code base to use the new struct event_location
API being introduced. This patch preserves the current functionality and
adds no new features.

The "big picture" API usage introduced by this patch may be illustrated
with a simple exmaple. Where previously developers would write:

void
my_command (char *arg, int from_tty)
{
   create_breakpoint (..., arg, ...);
   ...
}

one now uses:

void
my_command (char *arg, int from_tty)
{
   struct event_locaiton *location;
   struct cleanup *back_to;

   location = string_to_event_locaiton (&arg, ...);
   back_to = make_cleanup_delete_event_location (location);
   create_breakpoint (..., location, ...);
   do_cleanups (back_to);
}

Linespec-decoding functions (now called location-decoding) such as
decode_line_full no longer skip argument pointers over processed input.
That functionality has been moved into string_to_event_location as
demonstrated above.

4f45d44599 Remove --xdb
Pedro Alves:

The commands that enables aren't even documented in the manual.
Judging from that, I assume that only wdb users would ever really
be using the --xdb switch.

I think it's time to drop "support" for the --xdb switch too.  I
looked through the commands that that exposes, the only that looked
potentially interesting was "go", but then it's just an alias
for "tbreak+jump", which can easily be done with "define go...end".
I'd rather free up the "go" name for something potentially
more interesting (either run control, or maybe even unrelated,
e.g., for golang).

ef0b411a11 Add max-completions parameter, and implement tab-completion limiting.
This commit adds a new exception, MAX_COMPLETIONS_REACHED_ERROR, to be
thrown whenever the completer has generated too many candidates to
be useful.  A new user-settable variable, "max_completions", is added
to control this behaviour.  A top-level completion limit is added to
complete_line_internal, as the final check to ensure the user never
sees too many completions.  An additional limit is added to
default_make_symbol_completion_list_break_on, to halt time-consuming
symbol table expansions.
