When running gdb.ada/funcall_ref.exp I run into two XPASSes:
...
(gdb) p get ("Hello world!")^M
$1 = (n => 12, s => "Hello world!")^M
(gdb) XPASS: gdb.ada/funcall_ref.exp: p get ("Hello world!")
ptype get ("Hello world!")^M
type = <ref> record^M
n: natural;^M
s: access array (1 .. n) of character;^M
end record^M
(gdb) XPASS: gdb.ada/funcall_ref.exp: ptype get ("Hello world!")
...
The xfails are documented in funcall_ref.exp:
...
# Currently, GCC describes such functions as returning pointers (instead of
# references).
setup_xfail *-*-*
...
Using gnatmake 4.8, we can reproduce the XFAILs:
...
(gdb) p get ("Hello world!")^M
$1 = (access foo.bar) 0x6147b0 <system.secondary_stack.chunk+48>^M
(gdb) XFAIL: gdb.ada/funcall_ref.exp: p get ("Hello world!")
ptype get ("Hello world!")^M
type = access record^M
n: natural;^M
s: access array (1 .. n) of character;^M
end record^M
(gdb) XFAIL: gdb.ada/funcall_ref.exp: ptype get ("Hello world!")
...
Fix the XPASSes by:
- removing the xfail setup
- switching the order of the two tests
- detecting the "access record" type and declaring the first test unsupported,
and skipping the second test
Tested on x86_64-linux, both with gnatmake 4.8.5 and gnatmake 7.5.0.

If I de-install gnatbind, I run into:
...
FAIL: gdb.ada/catch_ex_std.exp: gnatbind foo

...
Likewise for gnatlink.
Tested on x86_64-linux, with and without gnatbind/gnatlink installed.

does not have debug info
This test verifies that GDB correctly identifies the run-time type of
"s" as being the type "Circle". However, that can only be done
correctly if the GNAT runtime has been compiled and shipped with debug
information, so that GDB can poke in its internal data structures.
Currently the test fails when when running against a GNAT runtime
without debug info. This is the case, for example, on Arch Linux using
the distribution package.
This patch adds a helper in lib/ada.exp to check whether the GNAT
runtime has debug info or not. It then uses it in
gdb.ada/ptype_tagged_param.exp to expect a different result, depending
on whether we have debug info or not in the runtime.
At first, I made it so we would XFAIL the test, in the absence of debug
info, but then I thought that we might as well test for the output we
expect in the absence of debug info instead.
gdb/testsuite/ChangeLog:
* lib/ada.exp (gnat_runtime_has_debug_info): New proc.
* lib/gnat_debug_info_test.adb: New file.
* gdb.ada/ptype_tagged_param.exp: Use
gnat_runtime_has_debug_info, expect a different output if
runtime does not have debug info.

Sometimes -- notably with unchecked unions -- the Ada "ptype" code
will print a "?" or "??" to indicate something unknown. The choice of
what was printed was somewhat arbitrary, and in one case, Ada would
print an empty string rather than "?".
This patch normalizes the Ada code to use "?" rather than an empty
string or "??". My reasoning here is that a single question mark is
enough to convey unknown-ness.

In MI mode, print_ada_task_info can crash in find_thread_ptid when

On openSUSE Leap 15.1, we have:
...
FAIL: gdb.ada/mi_task_arg.exp: -stack-list-arguments 1 (unexpected output)
...
The problem is that the stack-list-arguments command prints a frame argument
'self_id' for function system.tasking.stages.task_wrapper:
...
frame={level="2",args=[{name="self_id",value="0x12345678"}]
...
where none (args=[]) is expected.
The frame argument is in fact correct. The FAIL does not show for say, fedora
30, because there the executable uses the system.tasking.stages.task_wrapper
from /lib64/libgnarl-9.so. Adding "additional_flags=-bargs
additional_flags=-shared additional_flags=-largs" to the flags argument of
gdb_compile_ada gives us the same PASS, but installing libada7-debuginfo gets
us the same FAIL again.
Fix the FAIL by allowing the 'self_id' argument.
Tested on x86_64-linux.

Update a test script to handle the case where missing Ada debug
information means we can't catch exceptions. This was discussed on
the list here:
https://sourceware.org/ml/gdb-patches/2019-08/msg00607.html

gdb.ada/catch_ex.exp and gdb.ada/mi_catch_ex.exp.

This adds the $_ada_exception convenience variable. It is set by the
Ada exception catchpoints, and holds the address of the exception
currently being thrown. This is useful because it allows more
fine-grained filtering of exceptions than is possible using the
existing "catch" syntax.
This also simplifies Ada catchpoints somewhat; because the catchpoint
must now carry the "kind", it's possible to remove many helper
functions.

dwarf2read.c will create stub types for Ada "Taft Amendment" types.
These stub types can currently be exposed to Python code, where they
show up as TYPE_CODE_VOID types (but that, mysteriously, can sometimes
be used in other ways).
While it's possible to work with such types by using strip_typedefs,
this seemed unpleasant to me. This patch takes another approach
instead, which is to try not to expose stub types to Python users.

With this patch, we e.g. get:
[Switching to task 2 "task_list(1)"]
[Current task is 2 "task_list(1)"]
instead of
[Switching to task 2]
[Current task is 2]
The logic to produce the taskno optionally followed
by the task name has been factorized in the task_to_str function.
Task names are output between double quotes in the new messages,
similarly to what GDB does for thread names.
However, no quotes are put around task names in 'info tasks' Name column.
This was discussed with Tom, that preferred no quotes there, while I
was more in favour of visual consistency.
I discussed with a few more users, which led to (exactly) 50% preferring
quotes and 50% preferring no quotes :).
To arrive to the decision to remove the quotes, the following "killing args"
were used:
* To have quotes or to not have quotes, that is the question; yes
but not *THE* question :).
* If there is not a clear majority that prefers quotes, better to
not disturb the existing user basis for a (somewhat) irrelevant
aspect.
* The opinion of the reviewer has more weight.
So, compared to the previous version, this version remotes the quotes
in 'info tasks'.
It improves the alignement of 'info tasks' output.
With this patch, we get:
(gdb) info task
ID TID P-ID Pri State Name
* 1 555555759030 48 Runnable main_task
2 555555759e30 1 48 Selective Wait mit
(gdb)
instead of
(gdb) info task
ID TID P-ID Pri State Name
* 1 555555759030 48 Runnable main_task
2 555555759e30 1 48 Selective Wait mit
(gdb)
(e.g. the first one properly shows parent and priority under the
correct header).
This is version 4 of the 'task name' patch.
Compared to version 3, the changes are:
output task names between quotes but not in 'info tasks'

An internal Ada test case showed that the .debug_names code does not
compute the same list of file names as the partial symbol reader. In
particular, the partial symbol reader uses the DW_AT_name of the CU:
/* Allocate a new partial symbol table structure. */
filename = dwarf2_string_attr (comp_unit_die, DW_AT_name, cu);
if (filename == NULL)
filename = "";
pst = create_partial_symtab (per_cu, filename);

In Ada, the programmer can request that a range type with a non-zero
base be stored in the minimal number of bits required for the range.
This is done by biasing the values; so, for example, a range of -7..-4
may be stored as two bits with a bias of -7.
This patch implements this for gdb. It is done by adding a bias to
struct range_bounds and then adjusting a few spots to handle this.
The test case is written to use -fgnat-encodings=minimal, but a future
compiler patch will change the compiler to emit DW_AT_GNU_bias with
-fgnat-encodings=gdb. It seemed good to get the gdb patch in first.
Tested on x86-64 Fedora 29; plus a variety of targets using AdaCore's
internal test suite.

In Ada, it's possible to have nested functions. However,
block.c:contained_in does not recognize this. Normally, this is no
problem, but if gdb is stopped inside a nested function, then you can
end up in the unexpected situation that "print" of an expression will
work, whereas "display" of the same expression will not -- because
contained_in returns 0.
This patch simply removes the BLOCK_FUNCTION check from contained_in.
The rationale here is that in languages without nested functions, this
will not cause any issues.

Currently each language has a la_print_typedef method, this is only
used for the "info types" command.
The documentation for "info types" says:
Print a brief description of all types whose names match the regular
expression @var{regexp} (or all types in your program, if you supply
no argument).
However, if we consider this C code:
typedef struct {
int a;
} my_type;
Then currently with "info types" this will be printed like this:
3: typedef struct {
int a;
} my_type;
I see two problems with this, first the indentation is clearly broken,
second, if the struct contained more fields then it feels like the
actual type names could easily get lost in the noise.
Given that "info types" is about discovering type names, I think there
is an argument to be made that we should focus on giving _only_ the
briefest summary for "info types", and if the user wants to know more
they can take the type name and plug it into "ptype". As such, I
propose that a better output would be:
3: typedef struct {...} my_type;
The user understands that there is a type called `my_type`, and that
it's an alias for an anonymous structure type.
The change to achieve this turns out to be pretty simple, but only
effects languages that make use of c_print_typedef, which are C, C++,
asm, minimal, d, go, objc, and opencl. Other languages will for now
do whatever they used to do.
The patch to change how anonymous structs are displayed also changes
the display of anonymous enums, consider this code sample:
typedef enum {
AA, BB, CC
} anon_enum_t;
This used to be displayed like this:
3: typedef enum {AA, BB, CC} anon_enum_t;
Which will quickly become cluttered for enums with a large number of
values. The modified output looks like this:
3: typedef enum {...} anon_enum_t;
Again, the user can always make use of ptype if they want to see the
details of the anon_enum_t type.
It is worth pointing out that this change (to use {...}) only effects
anonymous structs and enums, named types don't change with this patch,
consider this code:
struct struct_t {
int i;
};
enum enum_t {
AA, BB, CC
};
The output from 'info types' remains unchanged, like this:
4: enum enum_t;
1: struct struct_t;
An additional area of interest is how C++ handles anonymous types used
within a typedef; enums are handled basically inline with how C
handles them, but structs (and classes) are slightly different. The
behaviour before the patch is different, and is unchanged by this
patch. Consider this code compiled for C++:
typedef struct {
int i;
} struct_t;
Both before and after this patch, this is show by 'info types' as:
3: typedef struct_t struct_t;
Unions are displayed similarly to structs in both C and C++, the
handling of anonymous unions changes for C in the same way that
it changes for anonymous structs.
I did look at ada, as this is the only language to actually have some
tests for "info types", however, as I understand it ada doesn't really
support typedefs, however, by forcing the language we can see what ada
would print. So, if we 'set language ada', then originally we printed
this:
3: record
a: int;
end record
Again the indentation is clearly broken, but we also have no mention
of the type name at all, which is odd, but understandable given the
lack of typedefs. If I make a similar change as I'm proposing for C,
then we now get this output:
3: record ... end record
Which is even less informative I think. However, the original output
_is_ tested for in gdb.ada/info_auto_lang.exp, and its not clear to me
if the change is a good one or not, so for now I have left this out.

When testing gdb with board cc-with-gdb-index, we run into:
...
FAIL: gdb.ada/ptype_union.exp: ptype global
FAIL: gdb.ada/ptype_union.exp: print global
...
The index is not supported for Ada (PR24713), and cc-with-gdb-index does not
add an index for Ada test-cases. However, this test-case compiles C sources,
for which cc-with-gdb-index does add an index. In gdb we load the executable
containing the index and set the language to Ada, resulting in gdb trying to
handle something that is not supported.
Fix the fail by marking this unsupported.

gdb could crash when setting a breakpoint condition on a breakpoint
when using the Ada language. The problem occurred because the
ada_evaluate_subexp would try to evaluate the array to compute its
attributes, but evaluating can't really be done at this time.
This patch fixes the problem by arranging not to try to evaluate in
EVAL_AVOID_SIDE_EFFECTS mode when computing an attribute.

In Ada mode, re-assigning an array of a different size to a
convenience variable will cause an error:
(gdb) set lang ada
(gdb) set $v := "abc"
(gdb) set $v := "abcd"

be possible to overwrite a convenience variable.

- set print frame-arguements all
- an Ada function named pck.call_me calls a C function named break_me
- you put a breakpoint in break_me and the program reaches this
breakpoint.
Now display the backtrace:
(gdb) bt
#0 break_me () at [...]
#1 0x000000000040243e in pck.call_me (
s={P_ARRAY = 0x7fffffffe21c, P_BOUNDS = 0x41e6e8}) at [...]
whereas we should expect:
(gdb) bt
#0 break_me () at [...]
#1 0x000000000040243e in pck.call_me (s="test") at [...]
The problem is that GDB prints the S parameter in the pck.call_me Ada
function using the current language, so the C one, because the program
is stopped in a C function, whereas it should use the pck.call_me frame
one. This behavior is ok when user manually changes the language but it's
not the right one when language is auto.
This patch fixes this problem so now when using auto language, all Ada
frame arguments are printed using Ada like syntax when the frame is part
of Ada code, even if the program is stopped in a frame using a different
language.
If the user explicitly sets a language (using "set language ...") then
no change here, all the Ada frame arguments are printed using this
language.

An internal bug report points out that, when a global character enum
type is used, casting fails, like:
(gdb) print global_char_enum'('F')
$1 = 70
The bug here turns out to be that enumerators are qualified, so for
example the mangled name might be "pck__QU48", rather than "QU48".
This patch fixes the problem by only examining the suffix of the
enumerator. This is ok because the type is already known, and because
the mangling scheme ensures that there won't be clashes.

When an Ada program is dynamically linked against libgnat, and when
one of the standard exceptions is used, the exception object may be
referenced by the main executable using a copy relocation.
In this situation, a "catch exception" for those exceptions will not
manage to stop. This happens because, under the hood, "catch
exception" creates an expression object that examines the object
addresses -- but in this case, the address will be incorrect.
This patch fixes the problem by arranging for these filter expressions
to examine all the relevant minimal symbols. This way, the object
from libgnat will be found as well.

ada-lang.c is a bit too eager trying to decode unions in the Ada style
-- looking for discriminants and such. This causes crashes when
printing a non-Ada union in Ada mode, something that can easily happen
when printing a value from history or certain registers on AArch64.
This patch fixes the bug by changing ada-lang.c to only apply special
Ada treatment to types coming from an Ada CU. This in turn required a
couple of surprising changes.
First, some of the Ada code was already using HAVE_GNAT_AUX_INFO to
decide whether a type had already been fixed -- such types had
INIT_CPLUS_SPECIFIC called on them. This patch changes these spots to
use the "none" identifier instead.
This then required changing value_rtti_type to avoid changing the
language-specific object attached to an Ada type, which seems like a
good change regardless.

Trying to print a packed array sometimes leads to a crash (see
attached testcase for an example of when this happens):
| (gdb) p bad
| [1] 65571 segmentation fault gdb -q foo
Variable "bad" is declared in the debug information as an array where
the array's type name has an XPnnn suffix:
| .uleb128 0xc # (DIE (0x566) DW_TAG_typedef)
| .long .LASF200 # DW_AT_name: "pck__t___XP1"
| [loc info attributes snipped]
| .long 0x550 # DW_AT_type
| .byte 0x1 # DW_AT_alignment
The signals to GDB that the debugging information follows a GNAT encoding
used for packed arrays, and an in order to decode it, we need to find
the type whose name is the same minus the "___XPnnn" suffix: "pck__t".
For that, we make a call to ada-lang.c::standard_lookup, which is
a simple function which essentially does:
| /* Return the result of a standard (literal, C-like) lookup of NAME in
| given DOMAIN, visible from lexical block BLOCK. */
|
| [...]
| sym = lookup_symbol_in_language (name, block, domain, language_c, 0);
Unfortunately for us, while the intent of this call was to perform
an exact-match lookup, in our case, it returns ... type pck__t___XP1
instead! In other words, it finds itself back. The reason why it finds
this type is a confluence of two factors:
(1) Forcing the lookup into language_c currently does not affect
how symbol matching is done anymore, because we look at the symbol's
language to determine which kind of matching should be done;
(2) The lookup searches the local context (via block) first, beforei
doing a more general lookup. And looking at the debug info for
the main subprogram, we see that type "pck__t" is not declared
there, only in the debug info for pck.ads. In other words,
there is no way that we accidently find "pck__t" by random chance.
I believe Pedro added a new function called ada_lookup_encoded_symbol
for that specific purpose, so I started by replacing the lookup
by language above by this. Unfortunately, still no joy.
This was because, even though ada_lookup_encoded_symbol puts angle-
brackets around the search name to signal that we want a verbatim
search, we end up losing that information in the function called
to compare a symbol with the search name:
| static bool
| do_full_match (const char *symbol_search_name,
| const lookup_name_info &lookup_name,
| completion_match_result *comp_match_res)
| {
| return full_match (symbol_search_name, ada_lookup_name (lookup_name));
^^^^^^^^^^^^^^^
|
<=> lookup_name.m_ada.m_encoded_name
(no angle brackets)
The way I fixed this was by introducing a new function called
do_exact_match, and then adjust ada_get_symbol_name_matcher to
return that function when seeing that we have a verbatim non-wild-match
search.
As it happens, this fixes an incorrect test in gdb.ada/homony.exp,
where we were inserting a breakpoint on a symbol using the angle-brackets
notation, and got 2 locations for that breakpoint...
(gdb) b <homonym__get_value>
Breakpoint 1 at 0x4029fc: <homonym__get_value>. (2 locations)
... each location being in a different function:
(gdb) info break
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x00000000004029fc in homonym.get_value
at /[...]/homonym.adb:32
1.2 y 0x0000000000402a3a in homonym.get_value
at /[...]/homonym.adb:50
(gdb) x /i 0x00000000004029fc

(gdb) x /i 0x0000000000402a3a
0x402a3a <homonym__get_value__2+8>: movl $0x11,-0x4(%rbp)
Since we used angle-brackets, we shouldn't be matching the second one,
something this patch fixes.

Consider the following variable, which is a string whose value
is not known at compile time, because it is the return value
from a function call (Get_Name):
A : String := Get_Name;
If one tries to create a varobj for that variable, everything works
as expected:
| (gdb) -var-create a * a
| ^done,name="a",numchild="19",value="[19] \"Some kind of string\"",type="<ref> array (1 .. 19) of character",thread-id="1",has_more="0"
However, try then to request an update, regardless of whether the string
has changed or not, and we get a crash:
| -var-update a
| ~"/[...]/gdb/varobj.c:1379: internal-error: bool install_new_value(varobj*, value*, bool): Assertion `!value_lazy (var->value.get ())' failed.\nA problem internal to GDB has been detected,\nfurther debugging may prove unreliable.\nQuit this debugging session? (y or n) "
When the varobj gets created (-var-create), the expression is evaluated
and transformed into a value. The debugging information describes our
variables as a reference to an array of characters, so our value has
the corresponding type. We then call varobj.c::install_new_value
to store that value inside our varobj, and we see that this function
pretty starts by determining weither our varobj is changeable, via:
| changeable = varobj_value_is_changeable_p (var);
(where 'var' is the varobj we are building, and where the function
varobj_value_is_changeable_p simply dispatches to the Ada version
of this routine: ada_value_is_changeable_p).
At this point, the varobj doesn't have a value, yet, but it does
have a type which was provided by varobj_create a little bit before
install_new_value was called. So ada_value_is_changeable_p uses that
to determine whether or not our type is changeable.
Since our type is a reference to an array, and that the value of
such objects is displayed as if there weren't a reference, it means
that our object is changeable -- in other words, if an element of
the string changes, then the "value" field of the varobj will change
accordingly. But unfortunately, ada_value_is_changeable_p mistakenly
returns false, because it is missing the handling of reference types.
As a consequence of this, install_new_value doesn't feel it is
necessary to fetch the value's contents, as explained by the following
comment inside that function:
/* The new value might be lazy. If the type is changeable,
that is we'll be comparing values of this type, fetch the
value now. Otherwise, on the next update the old value
will be lazy, which means we've lost that old value. */
This means that a lazy value gets installed inside our varobj
as a result of the mistake in ada_value_is_changeable_p.
Another important detail is that, after determining whether
our varobj is changeable or not, it then purposefully removes
the reference layer from our value:
/* We are not interested in the address of references, and given
that in C++ a reference is not rebindable, it cannot
meaningfully change. So, get hold of the real value. */
if (value)
value = coerce_ref (value);
The consequence of those two facts on shows up only later, when
the user requests an update (-var-update). When doing so, GDB
evaluates the expression again into a value which is once more
a reference to a string, and then calls install_new_value again
to install the new value and report any changes. This time around,
the call to...
| changeable = varobj_value_is_changeable_p (var);
... now gets a varobj which has a value, and one which had the reference
layer removed! So, this time, we classify the varobj correctly, and
say it is changeable. And because it is changeable, we then go into
the section of code in install_new_value which checks for changes,
where we need the varobj's value to not be lazy, as explained by
the comment we quoted above. That's what the assertion was about.
This patch fixes the issues by teaching ada_value_is_changeable_p
to ignore reference layers when evaluating a given varobj's type.

* ada-varobj.c (ada_value_is_changeable_p): Add handling of

With old compilers, the test fails because no debug info is generated
for 'B' and GDB finds some 'b' in atnat.h:
(gdb) print b
Multiple matches for b
[0] cancel
[1] b at ../sysdeps/ieee754/dbl-64/atnat.h:106
[2] b at ../sysdeps/ieee754/dbl-64/atnat.h:106
[3] b at ../sysdeps/ieee754/dbl-64/atnat.h:106
> FAIL: gdb.ada/rename_subscript_param.exp: print b before changing its value (timeout)
Avoid the timeout by renaming 'b' to rename_subscript_param_b.
Also, change 'before' to 'after' in the gdb_test message that prints
the value after changing it.
The test still fails with old compilers that do not properly
generate debug info for this renaming:
(gdb) print rename_subscript_param_b
No definition of "rename_subscript_param_b" in current context.
(gdb) FAIL: gdb.ada/rename_subscript_param.exp: print rename_subscript_param_b before changing its value
Note: if the compiler would generate the correct debug info, the test should
succeed with the name B. However, waiting for this fix, changing the name
ensures that the test fails directly, instead of causing a timeout.

The test gdb.ada/packed_array_assign fails due to conflict between component 'w'
and system.dim.mks.w:
(gdb) print pra := ((x => 2, y => 0, w => 17), pr, (x => 7, y => 1, w => 23))
Unknown component name: system.dim.mks.w.
(gdb) FAIL: gdb.ada/packed_array_assign.exp: print pra := ((x => 2, y => 0, w => 17), pr, (x => 7, y => 1, w => 23))
Also, depending on the compiler version, the component w might be reordered
and placed before components x and y.
So, change the component order in the source, so that both an old
compiler (GNATMAKE 6.3.0, gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516)
and a new compiler (GNATMAKE Pro 20.0w (20181210-82), based on gcc 8.2.1)
produce the same component order (checked by using -gnatR3s).
So, update to test the new (more unique) names in the source order.

* gdb.ada/packed_array_assign/aggregates.ads (Packed_Rec):
Rename components to Packed_Array_Assign_[X|Y|W]. Place

standard_ada_testfile, standard_test_file and the explicit
csrcfile assignment in info_auto_lang.exp all gives similar pathnames
prefix for a source, such as
/home/philippe/gdb/git/build_binutils-gdb/gdb/testsuite/../../../binutils-gdb/gdb/testsuite/gdb.<something>.
Note that the above pathnames contain ../ which appears when a relative
pathname is used to call configure.
In any case, the gnat compiler normalizes Ada sources path when compiling.
So, the 'Ada' .o object are referencing a pathname such as
/home/philippe/gdb/git/binutils-gdb/gdb/testsuite/gdb.ada/info_auto_lang/proc_in_ada.adb,
while the 'C' .o object still references the not normalized pathname.
As the results of 'info functions | ...' are sorted by pathname first,
the order of the results depends on the comparison between different directories,
leading to results that can change depending on these directories.
=> Ensure the result order is always the same, by normalising the C source file,
which makes the results independent of the way configure is launched.
Tested by running the testcase in 2 different builds, that without normalize
were giving different results.
Note: such 'set csrcfile' is used in 4 other tests mixing Ada and C.
After discussion, it was deemed sufficient to just normalize the pathname
for this test.

The "watch -l EXPR" command with the language set to Ada currently
fails with the following error:
(gdb) watch -l global_var
Error in expression, near ` 0x000000000062d2d8'.
The error occurs because GDB internally translate the request into
a watchpoint on a different expression: "* (TYPE *) ADDR" where
TYPE and ADDR are the type and the address of the object returned
by the expression's evaluation (resp.). So, in the example above,
global_var being an integer stored at 0x000000000062d2d8, GDB tries
to set a watchpoint on "* (integer *) 0x000000000062d2d8", which
fails, because we try to parse this expression with Ada, when
in fact it is not valid.
This patch fixes the issue by implementing the la_watch_location_expression
language method, using a syntax that the Ada parser recognizes
("{TYPE} ADDR").
gdb/ChangeLog:
* ada-lang.c (ada_watch_location_expression): New function.
(ada_language_defn): Set la_watch_location_expression to
ada_watch_location_expression.
gdb/testsuite/ChangeLog:
* gdb.ada/watch_minus_l: New testcase.

Currently, gdb.ada/complete.exp's "complete break ada" test fails
because the regexp used to match the command's output doesn't expect
"@", but we have an output like:
...
complete break ada
break ada.assertions.assert
break ada.calendar.arithmetic.difference
break ada.calendar.arithmetic_operations.add
break ada.calendar.arithmetic_operations.add.cold
break ada.calendar.arithmetic_operations.add@plt
break ada.calendar.arithmetic_operations.difference
break ada.calendar.arithmetic_operations.difference@plt
...
This patch adds "@" to the regexp, unbreaking the test.
OK?
