Andrew Burgess c9debfb97e gdb: Convert language la_get_symbol_name_matcher field to a method
This commit changes the language_data::la_get_symbol_name_matcher
function pointer member variable into a member function of
language_defn.

There should be no user visible changes after this commit.

Before this commit access to the la_get_symbol_name_matcher function
pointer was through the get_symbol_name_matcher function, which looked
something like this (is pseudo-code):

  <return-type>
  get_symbol_name_matcher (language_defn *lang, <other args>)
  {
    if (current_language == ada)
      current_language->la_get_symbol_name_matcher (<other args>);
    else
      lang->la_get_symbol_name_matcher (<other args>);
  }

In this commit I moved the get_symbol_name_matcher as a non-virtual
function in the language_defn base class, I then add a new virtual
method that is only used from within get_symbol_name_matcher, this can
then be overridden by specific languages as needed.  So we now have:

  class language_defn
  {
    <return-type> get_symbol_name_matcher (<args>)
    {
      if (current_language == ada)
        return current_language->get_symbol_name_matcher_inner (<args>);
      else
        return this->get_symbol_name_matcher_inner (<args>);
    }

    virtual <return-type> get_symbol_name_matcher_inner (<args>)
    {
        ....
    }
  }

Andrew Burgess 6f8270197a gdb: Convert language la_sniff_from_mangled_name field to a method
This commit changes the language_data::la_sniff_from_mangled_name
function pointer member variable into a member function of
language_defn.

Previously the la_sniff_from_mangled_name pointer was NULL for some
languages, however, all uses of this function pointer were through the
function language_sniff_from_mangled_name which provided a default
implementation.

This default implementation now becomes the implementation in the base
class language_defn, which is then overridden as required in various
language sub-classes.

There should be no user visible changes after this commit.

Tom Tromey 596dc4adff Speed up psymbol reading by removing a copy
I noticed that cp_canonicalize_string and friends copy a
unique_xmalloc_ptr to a std::string.  However, this copy isn't
genuinely needed anywhere, and it serves to slow down DWARF psymbol
reading.

This patch removes the copy and updates the callers to adapt.

This speeds up the reader from 1.906 seconds (mean of 10 runs, of gdb
on a copy of itself) to 1.888 seconds (mean of 10 runs, on the same
copy as the first trial).

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

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

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

Tested by the buildbot.

Tom Tromey 582942f456 More block constification
I noticed that there are still many places referring to non-const
blocks.  This constifies all the remaining ones that I found that
could be constified.

In a few spots, this search found unused variables or fields.  I
removed these.  I've also removed some unnecessary casts to
"struct block *".

Andrew Burgess 06d3e5b004 gdb: Remove a cleanup from find_overload_match
This patch changes cp-support.c:cp_func_name to return a
'gdb::unique_xmalloc_ptr<char>' instead of a 'char *'.  This allows a
cleanup to be removed from valops.c:find_overload_match.

gdb/ChangeLog:

	* compile/compile-cplus-types.c
	(compile_cplus_instance::decl_name): Handle changes to
	cp_func_name.
	* cp-support.c (cp_func_name): Update header comment, update
	return type.
	* cp-support.h (cp_func_name): Update return type in declaration.
	* valops.c (find_overload_match): Move temp_func local to top
	level of function and change its type.  Use temp_func to hold and
	delete temporary string obtained from cp_func_name.

Joel Brobecker 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.

gdb/ChangeLog:

	Update copyright year range in all GDB files.

Pedro Alves 0891c3cc13 Eliminate make_symbol_overload_list-related globals & cleanup
This gets rid of a few globals and a cleanup.

make_symbol_overload_list & friends currently maintain a global
open-coded vector.  Reimplement that with a std::vector, trickled down
through the functions.  Rename a few functions from "make_" to "add_"
for clarity.

Pedro Alves a20714ff39 Make "break foo" find "A::foo", A::B::foo", etc. [C++ and wild matching]
This patch teaches GDB about setting breakpoints in all scopes
(namespaces and classes) by default.

Here's a contrived example:

  (gdb) b func<tab>
  (anonymous namespace)::A::function()            Bn::(anonymous namespace)::B::function()        function(int, int)
  (anonymous namespace)::B::function()            Bn::(anonymous namespace)::function()           gdb::(anonymous namespace)::A::function()
  (anonymous namespace)::B::function() const      Bn::(anonymous namespace)::function(int, int)   gdb::(anonymous namespace)::function()
  (anonymous namespace)::function()               Bn::B::func()                                   gdb::(anonymous namespace)::function(int, int)
  (anonymous namespace)::function(int, int)       Bn::B::function()                               gdb::A::func()
  A::func()                                       Bn::func()                                      gdb::A::function()
  A::function()                                   Bn::function()                                  gdb::func()
  B::func()                                       Bn::function(int, int)                          gdb::function()
  B::function()                                   Bn::function(long)                              gdb::function(int, int)
  B::function() const                             func()                                          gdb::function(long)
  B::function_const() const                       function()
  (gdb) b function
  Breakpoint 1 at 0x4005ce: function. (26 locations)

  (gdb) b B::function<tab>
  (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()
  (gdb) b B::function
  Breakpoint 1 at 0x40072c: B::function. (6 locations)

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

Pedro Alves c62446b12b lookup_name_info::make_ignore_params
A few places in the completion code look for a "(" to find a
function's parameter list, in order to strip it, because psymtabs (and
gdb index) don't include parameter info in the symbol names.

See compare_symbol_name and
default_collect_symbol_completion_matches_break_on.

This is too naive.  Consider:

 ns_overload2_test::([TAB]

We'd want to complete that to:
 ns_overload2_test::(anonymous namespace)::struct_overload2_test

Or:

 b (anonymous namespace)::[TAB]

That currently completes to:

 b (anonymous namespace)

Which is obviously broken.  This patch makes that work.

Also, the current compare_symbol_name hack means that while this
works:

 "b function([TAB]"  ->  "b function()"

This does not:

 "b function ([TAB]"

This patch fixes that.  Whitespace "ignoring" now Just Works, i.e.,
assuming a symbol named "function(int, long)", this:
 b function (   int , lon[TAB]
completes to:
 b function (   int , long)

To address all of this, this patch builds on top of the rest of the
series, and pushes the responsibility of stripping parameters from a
lookup name to the new lookup_name_info object, where we can apply
per-language rules.  Also note that we now only make a version of the
lookup name with parameters stripped out where it's actually required
to do that, in the psymtab and GDB index code.

For C++, the right way to strip parameters is with "cp_remove_params",
which uses a real parser (cp-name-parser.y) to split the name into a
component tree and then discards parameters.

The trouble for completion is that in that case we have an incomplete
name, like "foo::func(int" and thus cp_remove_params throws an error.

This patch sorts that by adding a cp_remove_params_if_any variant of
cp_remove_params that tries removing characters from the end of the
string until cp_remove_params works.  So cp_remove_params_if_any
behaves like this:

With a complete name:

   "foo::func(int)"  => foo::func(int)  # cp_remove_params_1 succeeds the first time.

With an incomplete name:

   "foo::func(int"  => NULL             # cp_remove_params fails the first time.
   "foo::func(in"   => NULL             # and again...
   "foo::func(i"    => NULL             # and again...
   "foo::func("     => NULL             # and again...
   "foo::func"      => "foo::func"      # success!

Note that even if this approach removes significant rightmost
characters, it's still OK, because this parameter stripping is only
necessary for psymtabs and gdb index, where we're determining whether
to expand a symbol table.  Say cp_remove_params_if_any returned
"foo::" above for "foo::func(int".  That'd cause us to expand more
symtabs than ideal (because we'd expand all symtabs with symbols that
start with "foo::", not just "foo::func"), but then when we actually
look for completion matches, we'd still use the original lookup name,
with parameter information ["foo::func(int"], and thus we'll return no
false positive to the user.  Whether the stripping works as intended
and doesn't strip too much is thus covered by a unit test instead of a
testsuite test.

The "if_any" part of the name refers to the fact that while
cp_remove_params returns NULL if the input name has no parameters in
the first place, like:

   "foo::func"      => NULL         # cp_remove_params

cp_remove_params_if_any still returns the function name:

   "foo::func"      => "foo::func"  # cp_remove_params_if_any

Pedro Alves 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

Pedro Alves 2f408ecb92 Use ui_file_as_string throughout more
This replaces most of the remaining ui_file_xstrdup calls with
ui_file_as_string calls.  Whenever a call was replaced, that led to a
cascade of other necessary adjustments throughout, to make the code
use std::string instead of raw pointers.  And then whenever I added a
std::string as member of a struct, I needed to adjust
allocation/destruction of said struct to use new/delete instead of
xmalloc/xfree.

The stopping point was once gdb built again.  These doesn't seem to be
a way to reasonably split this out further.

Maybe-not-obvious changes:

 - demangle_for_lookup returns a cleanup today.  To get rid of that,
   and avoid unnecessary string dupping/copying, this introduces a
   demangle_result_storage type that the caller instantiates and
   passes to demangle_for_lookup.

 - Many methods returned a "char *" to indicate that the caller owns
   the memory and must free it.  Those are switched to return a
   std::string instead.  Methods that return a "view" into some
   internal string return a "const char *" instead.  I.e., we only
   copy/allocate when necessary.

Tom Tromey 8b302db80c Move logic out of symbol_find_demangled_name
This patch moves most of the demangling logic out of
symbol_find_demangled_name into the various language_defn objects.

The simplest way to do this seemed to be to add a new method to
language_defn.  This is shame given the existing la_demangle, but
given Ada's unusual needs, and the differing demangling options
between languages, la_demangle didn't seem to fit.

In order to make this work, I made enum language order-sensitive.
This helps preserve the current ordering of demangling operations.

Pierre-Marie de Rodat 22cee43f9a [Ada] Add support for subprogram renamings
Consider the following declaration:

    function Foo (I : Integer) return Integer renames Pack.Bar;

As Foo is not materialized as a routine whose name is derived from Foo,
GDB currently cannot use it:

    (gdb) print foo(0)
    No definition of "foo" in current context.

However, compilers can emit DW_TAG_imported_declaration in order to
materialize the fact that Foo is actually another name for Pack.Bar.
This commit enhances the DWARF reader to record global renamings (it
used to put global ones in a static block) and enhances the Ada engine
to leverage this information during symbol lookup.

gdb/ChangeLog:

	* ada-lang.c: Include namespace.h
	(aux_add_nonlocal_symbols): Fix a function name in comment.
	(ada_add_block_renamings): New.

	(ada_lookup_symbol_list_worker): Move the symbol lookup part
	to...
	(ada_add_all_symbols): ... this new function.
	(ada_add_block_symbols): Try to match the input name against the
	"using directives list", perform a recursive symbol lookup on
	the matched declarations.
	* block.h (struct block): Move the_namespace to top-level as
	namespace_info. Remove the language_specific field.
	(BLOCK_NAMESPACE): Update access to the namespace_info field.
	* buildsym.h (using_directives): Rename into...
	(local_using_directives): ... this.
	(global_using_directives): New.
	(struct context_stack): Rename the using_directives field into
	local_using_directives.
	* buildsym.c (finish_block_internal): Deal with the proper
	using directives repository (local or global).
	(prepare_for_building): Reset local_using_directives. Assert
	that there is no pending global using directive.
	(reset_symtab_globals): Reset global_using_directives and
	local_using_directives.
	(end_symtab_get_static_block): Don't ignore symtabs that have
	only using directives.
	(push_context): Update references to local_using_directives.
	(buildsym_init): Do not reset using_directives.
	* cp-support.c: Include namespace.h.

Pierre-Marie de Rodat d12307c199 Replace the block_found global with explicit data-flow
As Pedro suggested on gdb-patches@ (see
https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this
change makes symbol lookup functions return a structure that includes
both the symbol found and the block in which it was found.  This makes
it possible to get rid of the block_found global variable and thus makes
block hunting explicit.

Pedro Alves fe978cb071 C++ keyword cleanliness, mostly auto-generated
This patch renames symbols that happen to have names which are
reserved keywords in C++.

Most of this was generated with Tromey's cxx-conversion.el script.
Some places where later hand massaged a bit, to fix formatting, etc.
And this was rebased several times meanwhile, along with re-running
the script, so re-running the script from scratch probably does not
result in the exact same output.  I don't think that matters anyway.
