I noticed that "info locals" on a certain large Ada program was very
slow. I tracked this down to ada_get_tsd_type expanding nearly every
CU in the program.
This patch fixes the problem by changing this code to use the more
efficient lookup_transparent_type which, unlike the Ada-specific
lookup functions, does not try to find all matching instances.
Note that I first tried fixing this by changing ada_find_any_type, but
this did not work -- I may revisit this approach at some later date.
Also note that the copyright dates on the test files are set that way
because I copied them from another test.
New in v2: the new test failed on the Linaro regression tester.
Looking at the logs, it seems that gdb was picking up a 'value' from
libgnat:
$1 = {<text variable, no debug info>} 0xf7e227a4 <ada.calendar.formatting.value>
This version renames the local variable in an attempt to work around
this.
v3: In v2, while trying to reproduce the problem locally, I
accidentally forgot to commit one of the changes.

This changes lookup_symbol and associated APIs to accept
domain_search_flags rather than a domain_enum.
Note that this introduces some new constants to Python and Guile. I
chose to break out the documentation patch for this, because the
internals here do not change until a later patch, and it seemed
simpler to patch the docs just once, rather than twice.

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

I noticed a comment by an include and remembered that I think these
don't really provide much value -- sometimes they are just editorial,
and sometimes they are obsolete. I think it's better to just remove
them. Tested by rebuilding.

Currently, on any remotely modern GNU/Linux system,
gdb.cp/no-dmgl-verbose.exp fails like so:
break 'f(std::string)'
Function "f(std::string)" not defined.
(gdb) FAIL: gdb.cp/no-dmgl-verbose.exp: gdb_breakpoint: set breakpoint at 'f(std::string)'
break 'f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
Function "f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)" not defined.
(gdb) PASS: gdb.cp/no-dmgl-verbose.exp: DMGL_VERBOSE-demangled f(std::string) is not defined
This testcase was added back in 2011, here:
[patch] Remove DMGL_VERBOSE
https://sourceware.org/pipermail/gdb-patches/2011-June/083081.html
Back then, the testcase would pass cleanly. It turns out that the
reason it fails today is that the testcase is exercising something in
GDB that only makes sense if the program is built for the pre-C++11
libstc++ ABI. Back then the C++11 ABI didn't exist yet, but nowadays,
you need to compile with -D_GLIBCXX_USE_CXX11_ABI=0 to use the old
ABI. See "Dual ABI" in the libstdc++ manual, at
<https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html>.
If we tweak the gdb.cp/no-dmgl-verbose.exp testcase to force the old
ABI with -D_GLIBCXX_USE_CXX11_ABI=0, then it passes cleanly.
So why is it that setting a breakpoint at "f(std::string)" fails with
modern ABI, but passes with old ABI?
This is where libiberty demangler's DMGL_VERBOSE option comes in. The
Itanium ABI mangling scheme has a shorthand form for std::string (and
some other types). See
<https://itanium-cxx-abi.github.io/cxx-abi/abi.html>:
"In addition, the following catalog of abbreviations of the form "Sx" are used:
<substitution> ::= St # ::std::
<substitution> ::= Sa # ::std::allocator
<substitution> ::= Sb # ::std::basic_string
<substitution> ::= Ss # ::std::basic_string < char,
::std::char_traits<char>,
::std::allocator<char> >
<substitution> ::= Si # ::std::basic_istream<char, std::char_traits<char> >
<substitution> ::= So # ::std::basic_ostream<char, std::char_traits<char> >
<substitution> ::= Sd # ::std::basic_iostream<char, std::char_traits<char> >
"
When the libiberty demangler encounters such a abbreviation, by
default, it expands it to the user-friendly typedef "std::string",
"std::iostream", etc.. If OTOH DMGL_VERBOSE is specified, the
abbreviation is expanded to the underlying, non-typedefed fullname
"std::basic_string<char, std::char_traits<char>, std::allocator<char> >"
etc. as documented in the Itanium ABI, and pasted above. You can see
the standard abbreviations/substitutions in
libiberty/cp-demangle.c:standard_subs.
Back before Jan's patch in 2011, there were parts of GDB that used
DMGL_VERBOSE, and others that did not, leading to mismatches. The
solution back then was to stop using DMGL_VERBOSE throughout.
GDB has code in place to let users set a breakpoint at a function with
typedefs in its parameters, like "b f(uint32_t)". Demangled function
names as they appear in the symbol tables almost (more on this is in a
bit) never have typedefs in them, so when processing "b f(uint32_t)"
GDB first replaces "uint32_t" for its underlying type, and then sets a
breakpoint on the resulting prototype, in this case "f(unsigned int)".
Now, if DMGL_VERBOSE is _not_ used, then the demangler demangles the
mangled name of a function such as "void f(std::string)" that was
mangled using the standard abbreviations mentioned above really as:
"void f(std::string)".
For example, the mangled name of "void f(std::string)" if you compile
with old pre-C++11 ABI is "_Z1fSs". That uses the abbreviation "Ss",
so if you demangle that without DMGL_VERBOSE, you get:
$ echo "_Z1fSs" | c++filt --no-verbose
f(std::string)
while with DMGL_VERBOSE you'd get:
$ echo "_Z1fSs" | c++filt
f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)
If, when the user sets a breakpoint at "f(std::string)", GDB would
replace the std::string typedef for its underlying type using the same
mechanism I mentioned for the "f(uint32_t)" example above, then GDB
would really try to set a breakpoint at "f(std::basic_string<char,
std::char_traits<char>, std::allocator<char> >)", and that would fail,
as the function symbol GDB knows about for that function, given no
DMGL_VERBOSE, is "f(std::string)".
For this reason, the code that expands typedefs in function parameter
names has an exception for std::string (and other standard
abbreviation types), such that "std::string" is never
typedef-expanded.
And here lies the problem when you try to do "b f(std::string)" with a
program compiled with the C++11 ABI. In that case, std::string
expands to a different underlying type, like so:
f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)
and this symbol naturally mangles differently, as:
_Z1fNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
and then because this doesn't use the shorthand mangling abbreviation
for "std::string" anymore, it always demangles as:
f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)
Now, when using the C++11 ABI, and you set a breakpoint at
"f(std::string)", GDB's typedefs-in-parameters expansion code hits the
exception for "std::string" and doesn't expand it, so the breakpoint
fails to be inserted, because the symbol that exists is really the
f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)
one, not "f(std::string)".
So to fix things for C++11 ABI, clearly we need to remove the
"std::string" exception from the typedef-in-parameters expansion
logic. If we do just that, then "b f(std::string)" starts working
with the C++11 ABI.
However, if we do _just_ that, and nothing else, then we break
pre-C++11 ABI...
The solution is then to in addition switch GDB to always use
DMGL_VERBOSE. If we do this, then pre-C++11 ABI symbols works the
same as C++11 ABI symbols overall -- the demangler expands the
standard abbreviation for "std::string" as "std::basic_string<char,
std::char_traits<char>, std::allocator<char> >" and letting GDB expand
the "std::string" typedef (etc.) too is no longer a problem.
To avoid getting in the situation where some parts of GDB use
DMGL_VERBOSE and others not, this patch adds wrappers around the
demangler's entry points that GDB uses, and makes those force
DMGL_VERBOSE.
The point of the gdb.cp/no-dmgl-verbose.exp testcase was to try to
ensure that DMGL_VERBOSE doesn't creep back in:
gdb_test {break 'f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'} \
{Function ".*" not defined\.} \
"DMGL_VERBOSE-demangled f(std::string) is not defined"
This obviously no longer makes sense to have, since we now depend on
DMGL_VERBOSE. So the patch replaces gdb.cp/no-dmgl-verbose.exp with a
new gdb.cp/break-f-std-string.exp testcase whose purpose is to make
sure that setting a breakpoint at "f(std::string)" works. It
exercises both pre-C++11 ABI and C++11 ABI.

I noticed that some methods in language_defn could use
unique_xmalloc_ptr<char> rather than a plain 'char *'. This patch
implements this change, fixing up the fallout and changing
gdb_demangle to also return this type. In one spot, std::string is
used to simplify some related code, and in another, an auto_obstack is
used to avoid manual management.
Regression tested on x86-64 Fedora 34.

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>)
{
....
}

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.

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).

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.

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 *".

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.

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.

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.

Update copyright year range in all GDB files

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

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

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

gdb/ChangeLog:
Update copyright year range in all GDB files.

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.

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.

gdb/ChangeLog:
Update year range in copyright notice of all files.

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.

only using directives.

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.

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.
