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

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.

9a6c7d9c02 C++ify gdb/common/environ.c 
As part of the preparation necessary for my upcoming task, I'd like to
propose that we turn gdb_environ into a class.  The approach taken
here is simple: the class gdb_environ contains everything that is
needed to manipulate the environment variables.  These variables are
stored in an std::vector<char *>, which can be converted to a 'char
**' and passed as argument to functions that need it.

The usage has not changed much.  As per Pedro's suggestion, this class
uses a static factory method initialization.  This means that when an
instance is created, it is initially empty.  When needed, it has to be
initialized using the static method 'from_host_environ'.

As mentioned before, this is a preparation for an upcoming work that I
will be posting in the next few weeks or so.  For that work, I'll
probably create another data structure that will contain all the
environment variables that were set by the user using the 'set
environment' command, because I'll need access to them.  This will be
much easier with the class-ification of gdb_environ.

As noted, this has been regression-tested with the new version of
environ.exp and no regressions were found.

d5722aa2fe Introduce gdb::byte_vector, add allocator that default-initializes 
In some cases we've been replacing heap-allocated gdb_byte buffers
managed with xmalloc/make_cleanup(xfree) with gdb::vector<gdb_byte>.
That usually pessimizes the code a little bit because std::vector
value-initializes elements (which for gdb_byte means
zero-initialization), while if you're creating a temporary buffer,
you're most certaintly going to fill it in with some data.  An
alternative is to use

  unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);

but it looks like that's not very popular.

Recently, a use of obstacks in dwarf2read.c was replaced with
std::vector<gdb_byte> and that as well introduced a pessimization for
always memsetting the buffer when it's garanteed that the zeros will
be overwritten immediately.  (see dwarf2read.c change in this patch to
find it.)

So here's a different take at addressing this issue "by design":

#1 - Introduce default_init_allocator<T>

I.e., a custom allocator that does default construction using default
initialization, meaning, no more zero initialization.  That's the
default_init_allocation<T> class added in this patch.

See "Notes" at
<http://en.cppreference.com/w/cpp/container/vector/resize>.

#2 - Introduce def_vector<T>

I.e., a convenience typedef, because typing the allocator is annoying:

  using def_vector<T> = std::vector<T, gdb::default_init_allocator<T>>;

#3 - Introduce byte_vector

Because gdb_byte vectors will be the common thing, add a convenience
"byte_vector" typedef:

  using byte_vector = def_vector<gdb_byte>;

which is really the same as:

  std::vector<gdb_byte, gdb::default_init_allocator<gdb_byte>>;

The intent then is to make "gdb::byte_vector" be the go-to for dynamic
byte buffers.  So the less friction, the better.

#4 - Adjust current code to use it.

To set the example going forward.  Replace std::vector uses and also
unique_ptr<byte[]> uses.

One nice thing is that with this allocator, for changes like these:

  -std::unique_ptr<byte[]> buf (new gdb_byte[some_size]);
  +gdb::byte_vector buf (some_size);
   fill_with_data (buf.data (), buf.size ());

the generated code is the same as before.  I.e., the compiler
de-structures the vector and gets rid of the unused "reserved vs size"
related fields.

The other nice thing is that it's easier to write
  gdb::byte_vector buf (size);
than
  std::unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);
or even (C++14):
  auto buf = std::make_unique<gdb_byte[]> (size); // zero-initializes...

#5 - Suggest s/std::vector<gdb_byte>/gdb::byte_vector/ going forward.

Note that this commit actually fixes a couple of bugs where the current
code is incorrectly using "std::vector::reserve(new_size)" and then
accessing the vector's internal buffer beyond the vector's size: see
dwarf2loc.c and charset.c.  That's undefined behavior and may trigger
debug mode assertion failures.  With default_init_allocator,
"resize()" behaves like "reserve()" performance wise, in that it
leaves new elements with unspecified values, but, it does that safely
without triggering undefined behavior when you access those values.

c1fc265720 C++ify breakpoint class hierarchy (destructors only) 
Breakpoints are currently in a limbo state between C and C++.  There is
a pseudo class hierarchy implemented using struct fields.  Taking
watchpoint as an example:

  struct watchpoint
  {
    /* The base class.  */
    struct breakpoint base;

    ...
  }

and it is instantianted with "new watchpoint ()".  When destroyed, a
destructor is first invoked through the breakpoint_ops, and then the
memory is freed by calling delete through a pointer to breakpoint.
Address sanitizer complains about this, for example, because we new and
delete the same memory using different types.

This patch takes the logical step of making breakpoint subclasses extend
the breakpoint class for real, and converts their destructors to actual
C++ destructors.

Regtested on the buildbot.

5ed8105e02 RAII-fy make_cleanup_restore_current_thread & friends 
After all the make_cleanup_restore_current_thread fixing, I thought
I'd convert that and its relatives (which are all cleanups) to RAII
classes.

scoped_restore_current_pspace_and_thread was put in a separate file to
avoid a circular dependency.

Tested on x86-64 Fedora 23, native and gdbserver.

This introduces command_line_up, a unique_ptr for command_line
objects, and changes many places to use it.  This removes a number of

Command lines are funny in that sometimes they are reference counted.
Once there is more C++-ification of some of the users, perhaps all of
these can be changed to use shared_ptr instead.

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.

fdf9e36fa2 -Wwrite-strings: MI -info-os 
-Wwrite-strings flags this attempt to convert a string literal to
 "char *":

      info_osdata_command ("", 0);

info_osdata_command is a command function.  We could address this by
simply passing NULL instead of "".  However, I went a little bit
further and added a new function that is called by both the CLI and
MI.

51457a0578 Add -file-list-shared-libraries MI command 
This change adds the MI equivalent for the "info sharedlibrary"
command. The command was already partially documented but ignored as
it was not implemented. The new MI command works similarly to the CLI
command, taking an optional regular expression as an argument and
outputting the library information.

I included a test for the new command in mi-solib.exp.

gdb/doc/ChangeLog:

	* gdb.texinfo (gdb/mi Symbol Query Commands): Document new MI
	command file-list-shared-libraries
	(GDB/MI Async Records): Update documentation of library-loaded with new
	field.

	* NEWS: Add an entry about new '-file-list-shared-libraries' command.
	* mi/mi-cmd-file.c (mi_cmd_file_list_shared_libraries):
	New function definition.
	* mi/mi-cmds.c (mi_cmds): Add -file-list-shared-libraries command.

d6f9b0fbc7 C++-fy struct interp/cli_interp/tui_interp/mi_interp 
- The interp->data field disappears, since we can put data in the
  interpreter directly now.  The "init" method remains in place, but
  it now returns void.

- A few places check if the interpreter method is NULL before calling
  it, and also check whether the method returns true/false.  For some
  of those methods, all current implementations always return true.
  In those cases, this commit makes the C++-fied method return void
  instead and cleans up the callers.

Tested on x86_64 Fedora 23.

616268b639 Move "tee" building down to interpreter::set_logging_proc 
This patch gets rid of this hack in mi_set_logging:

      /* The tee created already is based on gdb_stdout, which for MI
	 is a console and so we end up in an infinite loop of console
	 writing to ui_file writing to console etc.  So discard the
	 existing tee (it hasn't been used yet, and MI won't ever use
	 it), and create one based on raw_stdout instead.  */

By pushing down responsibility for the tee creation to the
interpreter.  I.e., pushing the CLI bits out of handle_redirections
down to the CLI interpreter's set_logging_proc method.

This fixes a few leaks that I spotted, and then confirmed with
"valgrind --leak-check=full":

One is fixed by transfering ownership of the log file to the tee.  In
pseudo-patch, since the code was moved at the same time:

 -     out = new tee_file (curr_output, false, logfile.get (), false);
 +     out = new tee_file (curr_output, false, logfile.get (), true);

The other is this bit in mi_set_logging:

    else
      {
 +      delete mi->raw_stdout;

I tried to split the leak fixes to a smaller preparatory patch, but
that was difficult exactly because of the tee hack in
handle_redirections -> mi_set_logging.

d7e747318f Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy 
This patch starts from the desire to eliminate
make_cleanup_ui_file_delete, but then goes beyond.  It makes ui_file &
friends a real C++ class hierarchy, and switches temporary
ui_file-like objects to stack-based allocation.

- mem_fileopen -> string_file

mem_fileopen is replaced with a new string_file class that is treated
as a value class created on the stack.  This alone eliminates most
make_cleanup_ui_file_delete calls, and, simplifies code a whole lot
(diffstat shows around 1k loc dropped.)

string_file's internal buffer is a std::string, thus the "string" in
the name.  This simplifies the implementation much, compared to
mem_fileopen, which managed growing its internal buffer manually.

- ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone

The new string_file class has a string() method that provides direct
writable access to the internal std::string buffer.  This replaced
ui_file_as_string, which forced a copy of the same data the stream had
inside.  With direct access via a writable reference, we can instead
move the string out of the string_stream, avoiding deep string
copying.

Related, ui_file_xstrdup calls are replaced with xstrdup'ping the
stream's string, and ui_file_obsavestring is replaced by
obstack_copy0.

With all those out of the way, getting rid of the weird ui_file_put
mechanism was possible.

- New ui_file::printf, ui_file::puts, etc. methods

These simplify / clarify client code.  I considered splitting
client-code changes, like these, e.g.:

  -  stb = mem_fileopen ();
  -  fprintf_unfiltered (stb, "%s%s%s",
  -		      _("The valid values are:\n"),
  -		      regdesc,
  -		      _("The default is \"std\"."));
  +  string_file stb;
  +  stb.printf ("%s%s%s",
  +	      _("The valid values are:\n"),
  +	      regdesc,
  +	      _("The default is \"std\"."));

In two steps, with the first step leaving fprintf_unfiltered (etc.)
calls in place, and only afterwards do a pass to change all those to
call stb.printf etc..  I didn't do that split, because (when I tried),
it turned out to be pointless make-work: the first pass would have to
touch the fprintf_unfiltered line anyway, to replace "stb" with
"&stb".

- gdb_fopen replaced with stack-based objects

This avoids the need for cleanups or unique_ptr's.  I.e., this:

      struct ui_file *file = gdb_fopen (filename, "w");
      if (filename == NULL)
 	perror_with_name (filename);
      cleanups = make_cleanup_ui_file_delete (file);
      // use file.
      do_cleanups (cleanups);

is replaced with this:

      stdio_file file;
      if (!file.open (filename, "w"))
 	perror_with_name (filename);
      // use file.

- odd contorsions in null_file_write / null_file_fputs around when to
  call to_fputs / to_write eliminated.

- Global null_stream object

A few places that were allocating a ui_file in order to print to
"nowhere" are adjusted to instead refer to a new 'null_stream' global
stream.

- TUI's tui_sfileopen eliminated.  TUI's ui_file much simplified

The TUI's ui_file was serving a dual purpose.  It supported being used
as string buffer, and supported being backed by a stdio FILE.  The
string buffer part is gone, replaced by using of string_file.  The
'FILE *' support is now much simplified, by making the TUI's ui_file
inherit from stdio_file.

78cbbba8e0 Add command to erase all flash memory regions 
Changes in v4:

- Replaced phex call with hex_string.

Changes in v3:

- Addressed comments by Pedro.
- Output of memory region size now in hex format.
- Misc formatting fixups.
- Addressed Simon's comments on formatting.
- Adjusted command text in the manual entry.
- Fixed up ChangeLog.
- Renamed flash_erase_all_command to flash_erase_command.

Changes in v2:

- Added NEWS entry.
- Fixed long lines.
- Address printing with paddress.

Years ago we contributed flash programming patches upstream.  The following
patch is a leftover one that complements that functionality by adding a new
command to erase all reported flash memory blocks.

The command is most useful when we're dealing with flash-enabled targets
(mostly bare-metal) and we need to reset the board for some reason.

The wiping out of flash memory regions should help the target come up with a
known clean state from which the user can load a new image and resume
debugging. It is convenient enough to do this from the debugger, and there is
also an MI command to expose this functionality to the IDE's.

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...

33b2fac610 Simplify ui-out level code 
Now that we use a vector to store the levels, we don't have to keep a
separate level field in ui_out to keep track of the current level.  We
can efficiently derive it from the vector size.  That causes a little
change in the meaning of the level, as in they are now 1-based instead
of 0-based (the initial level has the "id" 1 now), but it shouldn't
change anything in the behavior.

Additionally, push_level and pop_level don't really need to return the
new level, making them return void simplifies the code a bit.

Finally, the ui_out_begin/ui_out_end callbacks in the ui_out_impl
interface don't need to be passed the level, it's never actually used.

New in v2:

 - Remove or update stale comments.

gdb/ChangeLog:

	* ui-out.h (ui_out_begin_ftype): Remove level parameter.
	(ui_out_end_ftype): Likewise.
	* ui-out.c (struct ui_out) <level>: Replace field with a method

	(current_level): Get vector's back item instead of using

	(ui_out_table_begin): Update access to uiout::level.

	call to uo_end.
	(verify_field): Update access to uiout->level.
	(ui_out_new): Don't initialize ui_out::level, call push_level
	to push the initial level instead of doing it by hand.

4a9d4ea535 Use std::vector for mi_ui_out_data::streams 
Use a standard vector instead of the home-made version.  I used a vector
of plain pointers, because the mi_ui_out_data object doesn't own the
streams objects (i.e. they shouldn't be deleted when the vector is
deleted).

5486f16481 Use new/delete instead of malloc/free-based functions 
The following patches introduce C++ vectors and strings as fields of the
various ui_out structures.  We therefore need to use new/delete so that
their contructor/destructor is called.  I find it simpler to change all
the allocations in a separate preliminary patch, rather than in each
individual patch.
