Tom Tromey 9b5587295b Change last_examine_value to value_ref_ptr
This patch removes some manual reference count manipulation by
changing last_examine_value to be a value_ref_ptr and then updating
the users.

	* printcmd.c (last_examine_address): Change type to
	value_ref_ptr.

Tom Tromey 22bc8444e6 Introduce a gdb_ref_ptr specialization for struct value
struct value is internally reference counted and so, while it also has
some ownership rules unique to it, it makes sense to use a gdb_ref_ptr
when managing it automatically.

This patch removes the existing unique_ptr specialization in favor of
a reference-counted pointer.  It also introduces two other
clarifications:

1. Rename value_free to value_decref, which I think is more in line
   with what the function actually does; and

2. Change release_value to return a gdb_ref_ptr.  This change allows
   us to remove the confusing release_value_or_incref function,
   primarily by making it much simpler to reason about the result of
   release_value.

Joel Brobecker 3fcded8f30 set varsize-limit: New GDB setting for maximum dynamic object size
This is a command we somehow forgot to contribute at the time the Ada
language was first contributed to the FSF. This command allows
the user to change the maximum size we allow when reading memory
from dynamic objects (the default is 65536 bytes).

At the moment, this limit is only used by Ada, and so the implementation
is kept inside ada-lang.c. However, it is conceivable that other language
might want to use it also to handle the same kind of issues; for instance,
this might be useful when handling dynamic types in C. So the name
of the setting was made language-neutral, to allow for this.

Note that an alias for "set var" needs to be introduced as well.
We are not adding a test for that, since this is a feature that is
already exercized by numerous existing tests.

gdb/ChangeLog

        * NEWS: Add entry describing new "set|show varsize-limit" command.
        * ada-lang.c (_initialize_ada_language): Add "set/show varsize-limit"
        command.
        * printcmd.c (_initialize_printcmd): Add "set var" alias of
        "set variable".

gdb/doc/ChangeLog:

        * gdb.texinfo (Ada Settings): New subsubsection.

gdb/testsuite/ChangeLog:

        * gdb.ada/varsize_limit: New testcase.

Tom Tromey 76727919ce Convert observers to C++
This converts observers from using a special source-generating script
to be plain C++.  This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).

Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.

Regression tested on the buildbot.

Andrew Burgess aee1fcdf97 gdb: New API for tracking innermost block
This commit is preparation for a later change, at this point there
should be no user visible change.

We currently maintain a global innermost_block which tracks the most
inner block encountered when parsing an expression.

This commit wraps the innermost_block into a new class, and switches all
direct accesses to the variable to use the class API.

Tom Tromey 8e481c3ba8 C++-ify parse_format_string
This replaces parse_format_string with a class, removing some
constructors along the way.  While doing this, I found that one
argument to gen_printf is unused, so I removed it.

Also, I am not completely sure, but the use of `release' in
maint_agent_printf_command and parse_cmd_to_aexpr seems like it may
leak expressions.

Regression tested by the buildbot.

Tom Tromey 85c4be7c83 Add set_repeat_arguments function
The "x", "list", and "show commands" commands have special repetition
behavior: repeating the command doesn't re-run it with the same
arguments

This is currently implemented by modifying the passed-in argument; but
that won't work properly with const arguments (and seems pretty
obscure besides).

This patch adds a new "set_repeat_arguments" function and changes the
relevant places to call it.

Ulrich Weigand f69fdf9bca Target FP: Add string routines to target-float.{c,h}
This adds target_float_to_string and target_float_from_string,
which dispatch to the corresponding floatformat_ or decimal_ routines.

Existing users of those routines are changed to use the new
target-float routines instead (most of those places already handle
both binary and decimal FP).

In addition, two other places are changes to use target_float_from_string:

- define_symbol in stabsread.c, when parsing a floating-point literal
  from stabs debug info

- gdbarch-selftest.c when initializing a target format values (to
  eliminate use of DOUBLEST there).

Ulrich Weigand 16e812b29e Target FP printing: Simplify and fix ui_printf
This patch adds support for handling format strings to both
floatformat_to_string and decimal_to_string, and then uses
those routines to implement ui_printf formatted printing.

There is already a subroutine printf_decfloat that ui_printf uses to
handle decimal FP.  This is renamed to printf_floating and updated
to handle both binary and decimal FP.  This includes the following
set of changes:

- printf_decfloat currently parses the format string again to determine
  the intended target format.  This seems superfluous since the common
  parsing code in parse_format_string already did this, but then did
  not pass the result on to its users.  Fixed by splitting the decfloat_arg
  argument class into three distinct classes, and passing them through.

- Now we can rename printf_decfloat to printf_floating and also call it
  for the argument classes representing binary FP types.

- The code will now use the argclass to detect the type the value should
  be printed at, and converts the input value to this type if necessary.
  To remain compatible with current behavior, for binary FP the code
  instead tries to re-interpret the input value as a FP type of the
  same size if that exists.  (Maybe this behavior is more confusing
  than useful -- but this can be changed later if we want to ...)

- Finally, we can use floatformat_to_string / decimal_to_string passing
  the format string to perform the formatted output using the desired
  target FP type.

Note that we no longer generate different code depending on whether or not
the host supports "long double" -- this check is obsolete anyway since C++11
mandates "long double", and in any case a %lg format string is intended to
refer to the *target* long double type, not the host version.

Note also that formatted printing of DFP numbers may not work correctly,
since it attempts to use the host printf to do so (and makes unwarranted
assumptions about the host ABI while doing so!).  This is no change to
the current behavior -- I simply moved the code from printf_decfloat to
the decimal_to_string routine in dfp.c.  If we want to fix it in the
future, that is a more appropriate place anyway.

ChangeLog:
2017-10-24  Ulrich Weigand  <uweigand@de.ibm.com>

	* common/format.h (enum argclass): Replace decfloat_arg by
	dec32float_arg, dec64float_arg, and dec128float_arg.
	* common/format.c (parse_format_string): Update to return

	* printcmd.c (printf_decfloat): Rename to ...

Ulrich Weigand fdf0cbc2b7 Target FP printing: Simplify and fix print_floating
The print_floating routine currently makes a lot of assumptions about host
and target floating point formats.  This patch cleans up many of those.

One problem is that print_floating may currently be called with types
that are not actually floating-point types, and it tries hard to output
those as floating-point values anyway.  However, there is only one single
caller of print_floating where this can ever happen: print_scalar_formatted.
And in fact, it is much simpler to handle the case where the value to be
printed is not already of floating-point type right there.

So this patch changes print_scalar_formatted to handle the 'f' format
as follows:

- If the value to be printed is already of floating-point type, just
  call print_floating on it.

- Otherwise, if there is a standard target floating-point type of
  the same size as the value, call print_floating using that type.

- Otherwise, just print the value as if the 'f' format had not been
  specified at all.

This has the overall effect to printing everything the same way as
the old code did, but is overall a lot simpler.  (Also, it would
allow us to change the above strategy more easily, if that might
be a more intuitive user interface.  For example, in the third
case above, maybe an error would be more appropriate?)

Given that change, print_floating can become much simpler.  In particular,
we now always have a floating-point format that we can consult.  This
means we can use the floating-point format to programmatically determine
the number of digits necessary to print the value.

The current code uses a hard-coded value of 9, 17, or 35 digits.  Note
that this matches the DECIMAL_DIG values for IEEE-32, IEEE-64, and
IEEE-128.  (Actually, for IEEE-128 the correct value is 36 -- the 35
seems to be an oversight.)  The DECIMAL_DIG value is defined to be
the smallest number so that any number in the target format, when
printed to this number of digits and then scanned back into a binary
floating-point number, will result in the original value.

Now that we always have a FP format, we can just compute the DECIMAL_DIG
value using the formula from the C standard.  This will be correct for
*all* FP formats, not just the above list, and it will be correct (as
opposed to current code) if the target formats differ from the host ones.

The patch moves the new logic to a new floatformat_to_string routine
(analogous to the existing decimal_to_string).  The print_floating
routine now calls floatformat_to_string or decimal_to_string, making
the separate print_decimal_floating and generic_val_print_decfloat routines
unnecessary.

Tom Tromey 981a3fb359 Constify add_prefix_cmd
This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.

In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors".  These overloads are temporary; once constification is
complete they can be removed.

This patch also fixes a typo I happened to notice while constifying.

Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build.  So, while I made a best-effort there, I am not
certain they will still compile.

Tested by rebuilding.

Ulrich Weigand 3b4b2f160d Clean up some DFP interfaces
This cleans up a number of interfaces in dfp.c / dfp.h.  Specifically:

- The decimal_from_string / decimal_to_string routines are C++-ified
  to operate on std::string instead of character buffers.  In the
  decimal_from_string, the boolean return value now actually is bool
  instead of an int.

- The decimal_from_integral and decimal_from_doublest routines take
  an struct value as input.  This is not really appropriate at the low
  level the DFP routines sit, so this replaced them with new routines
  decimal_from_longest / decimal_from_ulongest / decimal_from_doublest
  that operate on contents instead.

- To mirror the decimal_from_[u]longest, a new decimal_to_longest
  routine is added as well, which can be used in unpack_long to
  avoid an unnecessary conversion via DOUBLEST.

Note that the decimal_from_longest / decimal_from_ulongest routines
are actually more powerful than decimal_from_integral: the old routine
would only accept integer *types* of at most four bytes size, while
the new routines accept all integer *values* that fit in an [u]int32_t,
no matter which type they came from.  The DFP tests are updated to
allow for this larger range of integers that can be converted.

Tom Tromey 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.

Tom Tromey d6382fffde Fix two regressions in scalar printing
PR gdb/21675 points out a few regressions in scalar printing.

One type of regression is due to not carrying over the old handling of
floating point printing -- where a format like "/d" causes a floating
point number to first be cast to a signed integer.  This patch restores
this behavior.

The other regression is a longstanding bug in print_octal_chars: one of
the constants was wrong.  This patch fixes the constant and adds static
asserts to help catch this sort of error.

Pedro Alves 8268c77870 Eliminate make_cleanup_obstack_free, introduce auto_obstack
This commit eliminates make_cleanup_obstack_free, replacing it with a
new auto_obstack type that inherits obstack to add cdtors.

These changes in the parsers may not be obvious:

 -  obstack_init (&name_obstack);
 -  make_cleanup_obstack_free (&name_obstack);
 +  name_obstack.clear ();

Here, the 'name_obstack' variable is a global.  The change means that
the obstack's contents from a previous parse will stay around until
the next parsing starts.  I.e., memory won't be reclaimed until then.
I don't think that's a problem, these objects don't really grow much
at all.

The other option I tried was to add a separate type that is like
auto_obstack but manages an external obstack, just for those cases.  I
like the current approach better as that other approach adds more
boilerplate and yet another type to learn.

Pedro Alves 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.

Artemiy Volkov aa0061181a Convert lvalue reference type check to general reference type check
In almost all contexts (except for overload resolution rules and expression
semantics), lvalue and rvalue references are equivalent. That means that in all
but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE
check and, for switch statements, add a case label for a rvalue reference type
next to a case label for an lvalue reference type. This patch does exactly
that.

Pedro Alves 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.

Pedro Alves 01770bbde9 Fix PR 20559 - "eval" command and $arg0...$arg9/$argc substitution
It'd be handy to be able to iterate over command arguments in
user-defined commands, in order to support optional arguments
($arg0..$argN).

I thought I could make it work with "eval", but alas, it doesn't work
currently.  E.g., with:

 define test
   set $i = 0
   while $i < $argc
     eval "print $arg%d", $i
     set $i = $i + 1
   end
 end

we get:

 (gdb) test 1
 $1 = void
 (gdb) test 1 2 3
 $2 = void
 $3 = void
 $4 = void
 (gdb)

The problem is that "eval" doesn't do user-defined command arguments
substitution after expanding its own argument.  This patch fixes that,
which makes the example above work:

 (gdb) test 1
 $1 = 1
 (gdb) test 1 2 3
 $2 = 1
 $3 = 2
 $4 = 3
 (gdb)

New test included, similar the above, but also exercises expanding
$argc.

I think this is likely to simplify many scripts out there, so I'm
adding an example to the manual and mentioning it in NEWS as well.

Yao Qi e8b24d9ff5 Remove parameter valaddr from la_val_print
Nowadays, we pass both val and return value of
value_contents_for_printing (val) to la_val_print.  The latter is
unnecessary.  This patch removes the second parameter of la_val_print,
and get valaddr in each language's implementation by calling
value_contents_for_printing.  Since value_contents_for_printing calls
value_fetch_lazy, I also make VAL non-const.

Note that
 - I don't clean up the valaddr usages in each language's routines,
 - I don't remove valaddr from apply_ext_lang_val_pretty_printer, and
   extension language ops apply_val_pretty_printer.

They can be done in followup patches.

Pedro Alves 4d01a485d2 'struct expression *' -> gdb::unique_xmalloc_ptr<expression>
This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:

  typedef gdb::unique_malloc_ptr<expression> expression_up;

and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.

Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.

[1] - I'd like to set the rule that types named with an "_up" suffix
      are unique_ptr typedefs.

Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects.  Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

Tom Tromey b7b633e9b1 Use RAII to save and restore scalars
This patch replaces many (but not all) uses of
make_cleanup_restore_integer with a simple RAII-based template class.
It also removes the similar restore_execution_direction cleanup in
favor of this new class.  Subsequent patches will replace other
similar cleanups with this class.

The class is typically instantiated using make_scoped_restore.  This
allows for template argument deduction.

Pedro Alves bfd282882d Convert tid_range_parser and get_number_or_range to classes
This converts tid_range_parser and get_number_or_range to be classes.
The various tid_range_parser_* and get_number_or_range_* functions
become methods on the respective classes.  Then it updates the users
to follow.

The rationale for the change is that this provides better
encapsulation.  For example, this forced me to think of a better
interface between tid_range_parser and get_number_or_range, since the
former peeked into the latter's internals a bit too much.  That ended
up resulting mostly in these two not-just-straight-1-1 changes:

  void
 -tid_range_parser_skip (struct tid_range_parser *parser)
 +tid_range_parser::skip_range ()
  {
 ...

 -  tid_range_parser_init (parser, parser->range_parser.end_ptr,
 -			 parser->default_inferior);
 +  m_range_parser.skip_range ();
 +  init (m_range_parser.string (), m_default_inferior);
  }

 and:

    /* If we successfully parsed a thread number or finished parsing a
       thread range, switch back to assuming the next TID is
       inferior-qualified.  */
 -  if (parser->range_parser.end_ptr == NULL
 -      || parser->range_parser.string == parser->range_parser.end_ptr)
 +  if (!m_range_parser.in_range ())
      {

For the same reason (encapsulation), this moves the enum
tid_range_state definition to within the tid_parser class's scope,
since that is private implementation detail.

While at it, switch to use "bool" for booleans.

Add negative repeat count to 'x' command
This change adds support for specifying a negative repeat count to
all the formats of the 'x' command to examine memory backward.
A new testcase 'examine-backward' is added to cover this new feature.

Here's the example output from the new feature:

Simon Marchi 7c543f7b07 Change some void* to gdb_byte*
There are a bunch of places where a void* is implicitely casted into a
gdb_byte*.  The auto-insert-casts script added explicit casts at those
places.  However, in many cases, it makes more sense to just change the
void* to a gdb_byte*.

Simon Marchi 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).
