aafdfb4edd [gdb] Fix heap-buffer-overflow in completion_tracker::build_completion_result 
When building gdb with address sanitizer and running test-case
gdb.base/completion.exp, we run into:
...
==5743==ERROR: AddressSanitizer: heap-buffer-overflow on address \
  0x60200025c02f at pc 0x000000cd9d64 bp 0x7fff3297da30 sp 0x7fff3297da28
READ of size 1 at 0x60200025c02f thread T0
    #0 0xcd9d63 in completion_tracker::build_completion_result(char const*, \
                     int, int) gdb/completer.c:2258
  ...
0x60200025c02f is located 1 bytes to the left of 1-byte region \
  [0x60200025c030,0x60200025c031)
...

This can be reproduced using just:
...
$ gdb
(gdb) p/d[TAB]
...

The problem is in this code in completion_tracker::build_completion_result:
...
      bool completion_suppress_append
        = (suppress_append_ws ()
           || match_list[0][strlen (match_list[0]) - 1] == ' ');
...
If strlen (match_list[0]) == 0, then we access match_list[0][-1].

Fix this by testing if the memory access is in bounds before doing the memory
access.

Tested on x86_64-linux.

	PR gdb/27003
	* completer.c (completion_tracker::build_completion_result): Don't
	access match_list[0][-1].

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues 
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

cf00cd6faf default-args: allow to define default arguments for aliases 
Currently, a user can define an alias, but cannot have default
arguments for this alias.

This patch modifies the 'alias' command so that default args can
be provided.
    (gdb) h alias
    Define a new command that is an alias of an existing command.
    Usage: alias [-a] [--] ALIAS = COMMAND [DEFAULT-ARGS...]
    ALIAS is the name of the alias command to create.
    COMMAND is the command being aliased to.

    Options:
      -a
        Specify that ALIAS is an abbreviation of COMMAND.
        Abbreviations are not used in command completion..

    GDB will automatically prepend the provided DEFAULT-ARGS to the list
    of arguments explicitly provided when using ALIAS.
    Use "help aliases" to list all user defined aliases and their default args.

    Examples:
    Make "spe" an alias of "set print elements":
      alias spe set print elements
    Make "elms" an alias of "elements" in the "set print" command:
      alias -a set print elms set print elements
    Make "btf" an alias of "backtrace -full -past-entry -past-main" :
      alias btf = backtrace -full -past-entry -past-main
    Make "wLapPeu" an alias of 2 nested "with":
      alias wLapPeu = with language pascal -- with print elements unlimited --
    (gdb)

The way 'default-args' is implemented makes it trivial to set default
args also for GDB commands (such as "backtrace") and for GDB pre-defined
aliases (such as "bt").  It was however deemed better to not allow to
define default arguments for pre-defined commands and aliases, to avoid
users believing that e.g. default args for "backtrace" would apply to "bt".

If needed, default-args could be allowed for GDB predefined commands
and aliases by adding a command
'set default-args GDB_COMMAND_OR_PREDEFINED_ALIAS [DEFAULT-ARGS...]'.

* 'alias' command now has a completer that helps to complete:
     - ALIAS (if the user defines an alias after a prefix),
     - the aliased COMMAND
     - the possible options for the aliased COMMAND.

* Help and apropos commands show the definitions of the aliases
  that have default arguments, e.g.
        (gdb) help backtrace
        backtrace, btf, where, bt
          alias btf = backtrace -full -past-entry -past-main
        Print backtrace of all stack frames, or innermost COUNT frames.
        Usage: backtrace [OPTION]... [QUALIFIER]... [COUNT | -COUNT]

        Options:
          -entry-values no|only|preferred|if-needed|both|compact|default
            Set printing of function arguments at function entry.
        ...

eca1f90cf4 Add completion styling 
Readline has a styling feature for completion -- if it is enabled, the
common prefix of completions will be displayed in a different style.
This doesn't work in gdb, because gdb implements its own completer.

This patch implements the feature.  However, it doesn't directly use
the Readline feature, because gdb can do a bit better: it can let the
user control the styling using the existing mechanisms.

This version incorporates an Emacs idea, via Eli: style the prefix,
the "difference character", and the suffix differently.

0fa7617d84 Mark move constructors as "noexcept" 
I recently learned that move constructors generally should be marked
"noexcept".  This ensures that standard containers will move objects
when possible, rather than copy them.

This patch fixes the cases I could find.  Note that implicitly-defined
or defaulted move constructors will automatically do what you'd
expect; that is, they are noexcept if all the members have noexcept
move constructors.

While doing this, I noticed a couple of odd cases where the move
constructor seemed to assume that the object being constructed could
have state requiring destruction.  I've fixed these as well.  See
completion_result and scoped_mmap.

99f1bc6aaa gdb: Don't corrupt completions hash when expanding the hash table 
Commit:

  commit 724fd9ba43
  Date:   Mon Jan 27 17:37:20 2020 +0000

      gdb: Restructure the completion_tracker class

caused the completion hash table to become corrupted if the table ever
needed to grow beyond its original size of 200 elements.

The hash table stores completion_tracker::completion_hash_entry
objects, but hashes them based on their name, which is only one field
of the object.

When possibly inserting a new element we compute the hash with
htab_hash_string of the new elements name, and then lookup matching
elements using htab_find_slot_with_hash.  If there's not matching
element we create a completion_hash_entry object within the hash
table.

However, when we allocate the hash we pass htab_hash_string to
htab_create_alloc as the hash function, and this is not OK.  This
means that when the hash table needs to grow, existing elements within
the hash are re-hashed by passing the completion_hash_entry pointer to
htab_hash_string, which obviously does not do what we expect.

The solution is to create a new hash function that takes a pointer to
a completion_hash_entry, and then calls htab_hash_string on the name
of the entry only.

This regression was spotted when running the gdb.base/completion.exp
test on the aarch64 target.

gdb/ChangeLog:

	* completer.c (class completion_tracker::completion_hash_entry)
	<hash_name>: New member function.
	(completion_tracker::discard_completions): New callback to hash a
	completion_hash_entry, pass this to htab_create_alloc.

19a2740f7f gdb: Remove C++ symbol aliases from completion list 
Consider debugging the following C++ program:

  struct object
  { int a; };

  typedef object *object_p;

  static int
  get_value (object_p obj)
  {
    return obj->a;
  }

  int
  main ()
  {
    object obj;
    obj.a = 0;

    return get_value (&obj);
  }

Now in a GDB session:

  (gdb) complete break get_value
  break get_value(object*)
  break get_value(object_p)

Or:

  (gdb) break get_va<TAB>
  (gdb) break get_value(object<RETURN>
  Function "get_value(object" not defined.
  Make breakpoint pending on future shared library load? (y or [n]) n

The reason this happens is that we add completions based on the
msymbol names and on the symbol names.  For C++ both of these names
include the parameter list, however, the msymbol names have some
differences from the symbol names, for example:

  + typedefs are resolved,
  + whitespace rules are different around pointers,
  + the 'const' keyword is placed differently.

What this means is that the msymbol names and symbol names appear to
be completely different to GDB's completion tracker, and therefore to
readline when it offers the completions.

This commit builds on the previous commit which reworked the
completion_tracker class.  It is now trivial to add a
remove_completion member function, this is then used along with
cp_canonicalize_string_no_typedefs to remove the msymbol aliases from
the completion tracker as we add the symbol names.

Now, for the above program GDB only presents a single completion for
'get_value', which is 'get_value(object_p)'.

It is still possible to reference the symbol using the msymbol name,
so a user can manually type out 'break get_value (object *)' if they
wish and will get the expected behaviour.

I did consider adding an option to make this alias exclusion optional,
in the end I didn't bother as I didn't think it would be very useful,
but I can easily add such an option if people think it would be
useful.

	function.
	* completer.h (completion_tracker::remove_completion): Declare new

724fd9ba43 gdb: Restructure the completion_tracker class 
In this commit I rewrite how the completion tracker tracks the
completions, and builds its lowest common denominator (LCD) string.
The LCD string is now built lazily when required, and we only track
the completions in one place, the hash table, rather than maintaining
a separate vector of completions.

The motivation for these changes is that the next commit will add the
ability to remove completions from the list, removing a completion
will invalidate the LCD string, so we need to keep hold of enough
information to recompute the LCD string as needed.

Additionally, keeping the completions in a vector makes removing a
completion expensive, so better to only keep the completions in the
hash table.

This commit doesn't add any new functionality itself, and there should
be no user visible changes after this commit.

For testing, I ran the testsuite as usual, but I also ran some manual
completion tests under valgrind, and didn't get any reports about
leaked memory.

6c2659886f gdb: add back declarations for _initialize functions 
I'd like to enable the -Wmissing-declarations warning.  However, it
warns for every _initialize function, for example:

      CXX    dcache.o
    /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
    /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
     _initialize_dcache (void)
     ^~~~~~~~~~~~~~~~~~

The only practical way forward I found is to add back the declarations,
which were removed by this commit:

    commit 481695ed5f
    Author: John Baldwin <jhb@FreeBSD.org>
    Date:   Sat Sep 9 11:02:37 2017 -0700

        Remove unnecessary function prototypes.

I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

be09caf15d Allow . character as part of command names. 
This patch adds . as an allowed character for user defined commands.
Combined with 'define-prefix', this allows to e.g. define a set of Valgrind
specific user command corresponding to the Valgrind monitor commands
(such as check_memory, v.info, v.set, ...).

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.

272d459434 Introduce complete_nested_command_line 
This adds a completion helper routine that makes it possible for a
command that takes another command as argument, such as "frame apply
all COMMAND" as "thread apply all COMMAND", to complete on COMMAND,
and have the completion machinery recurse and complete COMMAND as if
you tried to complete "(gdb) COMMAND".  I.e., we'll be able to
complete like this, for example:

 (gdb) thread apply all -[TAB]
 -c           -ascending   -q           -s
 (gdb) thread apply all -ascending frame apply all -[TAB]
 -c           -limit       -past-entry  -past-main   -q           -s
 (gdb) thread apply all -ascending frame apply all -past-main print -[TAB]
 -address         -elements        -pretty          -symbol
 -array           -null-stop       -repeats         -union
 -array-indexes   -object          -static-members  -vtbl
 (gdb) thread apply all -ascending frame apply all -past-main print glo[TAB]
 global1         global2

Above, the completer function understands that "thread apply all" is a
command, and then parses "-ascending" successfully and understand that
the rest of the string is "thread apply all"'s operand.  And then, the
process repeats for the "frame apply" command, and on and on.

e6ed716cd5 Migrate rest of compile commands to new options framework 
As I was in the neighbourhood, I converted the other "compile"
subcommands to the new options framework too.  Specifically, "compile
code" and "compile file".

The user-visible changes are:

  - All abbreviations of "-raw" are accepted now, instead of just -r.
    Obviously that means "-ra" is now accepted.

  - Option completion now works.

  - "compile file" did not have a completer yet, and now it knows to
    complete on filenames.

  - You couldn't use "compile file" with a file named "-something".
    You can now, with "compile file -- -something".

3844e605e6 Fix latent bug with custom word point completers 
Completion routines that use a custom word point, and that then
recurse into complete_line (e.g., if we make "thread apply" a custom
word point completer, and complete on the command passed as argument),
we stumble on this latent bug:

 (gdb) thread apply all pri[TAB]
 (gdb) thread apply all priprint

The problem is that there's a spot in complete_line_internal_1 that
rewinds the completion word but does not reflect that change in the
custom word point in the tracker.  This patch fixes it.

	* completer.c (complete_line_internal_1): Rewind completion word
	point.
	(completion_tracker::advance_custom_word_point_by): Change
	parameter type to int.
	* completer.h (completion_tracker::advance_custom_word_point_by):
	Likewise.

00b56dbe70 Fix latent bug in custom word point completion handling 
Without this fix, if we switch the "print" completer to custom word
point handling, we regress gdb.base/completion.exp like this:

 (gdb) p "break1.c FAIL: gdb.base/completion.exp: complete 'p "break1' (timeout)

The problem is that completing an expression that starts with double
quotes, and resolves to a filename, like this:

 (gdb) p "break1[TAB]

would change from this, with current master:

 (gdb) p "break1.c"|
         ^^^^^^^^^^|
                   \- cursor here

to this:

 (gdb) p "break1.c |
         ^^^^^^^^^^|
                   \- quote replaced by space

The issue is that completer.c:advance_to_completion_word misses
telling the completion tracker to emulate readline's handling of
completing a string when rl_find_completion_word returns a delimiter.

This commit fixes the latent bug.

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.

0ef209f22c Initialize variable word in complete 
The complete function should set parameter word to the end of the
word to complete. However, completion_find_completion_word may fail,
leaving word uninitialized.

To make sure word is always set, initialize it to the completion point
which is the end of the line parameter.

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.

230d2906b9 Rename gdb exception types

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.

d55e5aa6b2 Sort includes for files gdb/[a-f]*.[chyl]. 
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.

42a4f53d2b Update copyright year range in all GDB files. 
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

459a2e4ccf Change streq to return bool 
I wanted to use streq with std::unique in another (upcoming) patch in
this seres, so I changed it to return bool.  To my surprise, this lead
to regressions.  The cause turned out to be that streq was used as an
htab callback -- by casting it to the correct function type.  This
sort of cast is invalid, so this patch adds a variant which is
directly suitable for use by htab.  (Note that I did not add an
overload, as I could not get that to work with template deduction in
the other patch.)

a22ecf7026 Fix regression: expression completer and scope operator (PR gdb/22584) 
I noticed this regression in the expression completer:

 "(gdb) p std::[TAB]" => "(gdb) p std::std::"

obviously we should have not completed to "std::std::".

The problem is that in the earlier big completer rework, I missed
taking into account the fact that with expressions, the completion
word point is not always at the start of the symbol name (it is with
linespecs).

The fix is to run the common prefix / LCD string (what readline uses
to expand the input line) through make_completion_match_str too.

New testcase included, exercising both TAB completion and the complete
command.

60a20c1907 Factor out final completion match string building 
We have several places doing essentially the same thing; factor them
out to a central place.  Some of the places overallocate for no good
reason, or use strcat unnecessarily.  The centralized version is more
precise and to the point.

(I considered making the gdb::unique_xmalloc_ptr overload version of
make_completer_match_str try to realloc (not xrealloc) probably
avoiding an allocation in most cases, but that'd be probably overdoing
it, and also, now that I'm writing this I thought I'd try to see how
could we ever get to filename_completer with "text != word", but I
couldn't figure it out.  Running the testsuite with 'gdb_assert (text
== word);' never tripped on the assertion either.  So post gdb 8.1,
I'll probably propose a patch to simplify filename_completer a bit,
and the gdb::unique_xmalloc_str overload can be removed then.)

798a7429f9 Remove some unused variables 
This patch removes some unused variables, found with -Wunused.  I have
not removed everything reported by -Wunused, because some expressions
such as

  struct type *arg_type = check_typedef (value_type);

in bfin-tdep.c could have an unexpected but important side-effect.  I
removed others that I considered more low-risk, such as:

  struct gdbarch *gdbarch = get_objfile_arch (objfile);

with/without libipt and with/without babeltrace.

To get back the original behavior of interpreting the function name as
a fully-qualified name, you can use the new "-qualified" (or "-q")
option/flag (added by this commit).  For example:

 (gdb) b B::function
 (anonymous namespace)::B::function()        B::function() const                         Bn::B::function()
 (anonymous namespace)::B::function() const  B::function_const() const
 B::function()                               Bn::(anonymous namespace)::B::function()

vs:

 (gdb) b -qualified B::function
 B::function()              B::function() const        B::function_const() const

I've chosen "-qualified" / "-q" because "-f" (for "full" or
"fully-qualified") is already taken for "-function".

Note: the "-qualified" option works with both linespecs and explicit
locations.  I.e., these are equivalent:

 (gdb) b -q func
 (gdb) b -q -f func

and so are these:

 (gdb) b -q filename.cc:func
 (gdb) b -q -s filename.cc -f func
 (gdb) b -s filename.cc -q -f func
 (gdb) b -s filename.cc -f func -q

To better understand why I consider wild matching the better default,
consider what happens when we get to the point when _all_ of GDB is
wrapped under "namespace gdb {}".  I have a patch series that does
that, and when I started debugging that GDB, I immediately became
frustrated.  You'd have to write "b gdb::internal_error", "b
gdb::foo", "b gdb::bar", etc. etc., which gets annoying pretty
quickly.  OTOH, consider how this makes it very easy to set
breakpoints in classes wrapped in anonymous namespaces.  You just
don't think of them, GDB finds the symbols for you automatically.

(At the Cauldron a couple months ago, several people told me that they
run into a similar issue when debugging other C++ projects.  One
example was when debugging LLVM, which puts all its code under the
"llvm" namespace.)

Implementation-wise, what the patch does is:

  - makes C++ symbol name hashing only consider the last component of
    a symbol name. (so that we can look up symbol names by
    last-component name only).

  - adds a C++ symbol name matcher for symbol_name_match_type::WILD,
    which ignores missing leading specifiers / components.

  - adjusts a few preexisting testsuite tests to use "-qualified" when
    they mean it.

  - adds new testsuite tests.

  - adds unit tests.

Grows the gdb.linespec/ tests like this:

  -# of expected passes           7823
  +# of expected passes           8977

a207cff2da Handle custom completion match prefix / LCD 
A following patch will add support for wild matching for C++ symbols,
making completing on "b push_ba" on a C++ program complete to
std::vector<...>::push_back, std::string::push_back etc., like:

 (gdb) b push_ba[TAB]
 std::vector<...>::push_back(....)
 std::string<...>::push_back(....)

Currently, we compute the "lowest common denominator" between all
completion candidates (what the input line is adjusted to) as the
common prefix of all matches.  That's problematic with wild matching
as above, as then we'd end up with TAB changing the input line to
"b std::", losing the original input, like:

 (gdb) b push_ba[TAB]
 std::vector<...>::push_back(....)
 std::string<...>::push_back(....)
 (gdb) b std::

while obviously we'd want it to adjust itself to "b push_back(" instead:

 (gdb) b push_ba[TAB]
 std::vector<...>::push_back(....)
 std::string<...>::push_back(....)
 (gdb) b push_back(

This patch adds the core code necessary to support this, though
nothing really makes use of it yet in this patch.

a81aaca057 Fix completing an empty string 
Earlier while working on the big completer rework series, I managed to
break

 (gdb) [TAB]

locally, and make GDB crash, but only notice a few weeks down the
road, because we have no test for that...

I also noticed that:

 (gdb)     [TAB]

didn't work (didn't show all commands as matches), even though
entering a command with leading whitespace works:

 (gdb)     help

This commit fixes the latter and adds a testcase that covers both
issues.

The gdb.base/completion.exp change is necessary because the new test
has a file name that also starts with "gdb.base/complet", making that
particular test ambiguous.  Adding another letter disambiguates.

b5ec771e60 Introduce lookup_name_info and generalize Ada's FULL/WILD name matching 
Summary:
 - This is preparation for supporting wild name matching on C++ too.
 - This is also preparation for TAB-completion fixes.
 - Makes symbol name matching (think strcmp_iw) be based on a per-language method.
 - Merges completion and non-completion name comparison (think
   language_ops::la_get_symbol_name_cmp generalized).
 - Avoid re-hashing lookup name multiple times
 - Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling),
   both completion and non-completion.
 - Fixes Ada latent bug with verbatim name matches in expressions
 - Makes ada-lang.c use common|symtab.c completion code a bit more.

Ada's wild matching basically means that

 "(gdb) break foo"

will find all methods named "foo" in all packages.  Translating to
C++, it's roughly the same as saying that "break klass::method" sets
breakpoints on all "klass::method" methods of all classes, no matter
the namespace.  A following patch will teach GDB about fullname vs
wild matching for C++ too.  This patch is preparatory work to get
there.

Another idea here is to do symbol name matching based on the symbol
language's algorithm.  I.e., avoid dependency on current language set.

This allows for example doing

  (gdb) b foo::bar< int > (<tab>

and having gdb name match the C++ symbols correctly even if the
current language is C or Assembly (or Rust, or Ada, or ...), which can
easily happen if you step into an Assembly/C runtime library frame.

By encapsulating all the information related to a lookup name in a
class, we can also cache hash computation for a given language in the
lookup name object, to avoid recomputing it over and over.

Similarly, because we don't really know upfront which languages the
lookup name will be matched against, for each language we store the
lookup name transformed into a search name.  E.g., for C++, that means
demangling the name.  But for Ada, it means encoding the name.  This
actually forces us to centralize all the different lookup name
encoding in a central place, resulting in clearer code, IMO.  See
e.g., the new ada_lookup_name_info class.

The lookup name -> symbol search name computation is also done only
once per language.

The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are
generalized to work with both completion, and normal symbol look up.

At some point early on, I had separate completion vs non-completion
language vector entry points, but a single method ends up being better
IMO for simplifying things -- the more we merge the completion /
non-completion name lookup code paths, the less changes for bugs
causing completion vs normal lookup finding different symbols.

The ada-lex.l change is necessary because when doing

  (gdb) p <UpperCase>

then the name that is passed to write_ write_var_or_type ->
ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase",
and we end up doing a wild match against "UpperCase" lowercased by
ada_lookup_name_info's constructor.  I.e., "uppercase" wouldn't ever
match "UpperCase", and the symbol lookup fails.

This wouldn't cause any regression in the testsuite, but I added a new
test that would pass before the patch and fail after, if it weren't
for that fix.

This is latent bug that happens to go unnoticed because that
particular path was inconsistent with the rest of Ada symbol lookup by
not lowercasing the lookup name.

Ada's symbol_completion_add is deleted, replaced by using common
code's completion_list_add_name.  To make the latter work for Ada, we
needed to add a new output parameter, because Ada wants to return back
a custom completion candidates that are not the symbol name.

With this patch, minimal symbol demangled name hashing is made
consistent with regular symbol hashing.  I.e., it now goes via the
language vector's search_name_hash method too, as I had suggested in a
previous patch.

dw2_expand_symtabs_matching / .gdb_index symbol names were a
challenge.  The problem is that we have no way to telling what is the
language of each symbol name found in the index, until we expand the
corresponding full symbol, which is off course what we're trying to
avoid.  Language information is simply not considered in the index
format...  Since the symbol name hashing and comparison routines are
per-language, we now have a problem.  The patch sorts this out by
matching each name against all languages.  This is inneficient, and
indeed slows down completion several times.  E.g., with:

 $ cat script.cmd
 set pagination off
 set $count = 0
 while $count < 400
   complete b string_prin
   printf "count = %d\n", $count
   set $count = $count + 1
 end

 $ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd"

I get, before patch (-O2, x86-64):

 real    0m1.773s
 user    0m1.737s
 sys     0m0.040s

While after patch (-O2, x86-64):

 real    0m9.843s
 user    0m9.482s
 sys     0m0.034s

However, the following patch will optimize this, and will actually
make this use case faster compared to the "before patch" above:

 real    0m1.321s
 user    0m1.285s
 sys     0m0.039s

a87c142792 Add missing-END_CATCH detection/protection (to gdb's TRY/CATCH/END_CATCH) 
While we still have cleanups (i.e., make_cleanup & co), we must be
sure to add END_CATCH at the end of a TRY/CATCH/END_CATCH construct.
However, it's currently too easy to miss adding the END_CATCH, because
the code compiles anyway without it.  I realized this when I noticed
that another patch I was working on missed several adding END_CATCH in
several new TRY/CATCH uses.

This commit fixes that by making TRY open a new scope that is only
closed by END_CATCH.  This way, if you forget to add the END_CATCH,
then compilation fails due to the unbalanced curly braces.

This caught a couple places where we were missing END_CATCH in current
master, also fixed by the patch.

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.
