Fix testing gdb.rust/modules.exp against gdbserver
Currently several tests in gdb.rust/modules.exp fail with --target_board=native-gdbserver: Running src/gdb/testsuite/gdb.rust/modules.exp ... FAIL: gdb.rust/modules.exp: call f3() FAIL: gdb.rust/modules.exp: call self::f2() FAIL: gdb.rust/modules.exp: call self::super::f2() FAIL: gdb.rust/modules.exp: call super::f2() FAIL: gdb.rust/modules.exp: call self::super::super::f2() FAIL: gdb.rust/modules.exp: call super::super::f2() FAIL: gdb.rust/modules.exp: call ::f2() FAIL: gdb.rust/modules.exp: call extern modules::mod1::f2() This is because these tests rely on matching inferior output. However, when testing with gdbserver, inferior output goes to a separate terminal instead of to gdb's terminal, and so gdb_test won't cut it, as that is only reading from gdb's pty/gdb_spawn_id: (gdb) call f3() (gdb) FAIL: gdb.rust/modules.exp: call f3() call self::f2() (gdb) FAIL: gdb.rust/modules.exp: call self::f2() Fix this by using gdb_test_stdio instead, which handles output coming out of gdbserver's pty. Also, skip the tests if the target/board doesn't support inferior I/O at all. gdb/ChangeLog: 2017-11-16 Pedro Alves <palves@redhat.com> * gdb.rust/modules.exp: Skip tests that rely on inferior I/O if gdb,noinferiorio is set, and use gdb_test_stdio otherwise. |

Refactor endian handling in DFP routines
This patch moves endian conversion into the decimal_from_number and decimal_to_number routines, and removes it from all their callers, making the code simpler overall. No functional change. gdb/ChangeLog: 2017-11-16 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c (decimal_from_number): Add byte_order argument and call match_endianness. Error if unknown floating-point type. (decimal_to_number): Add byte_order argument and call match_endianness. (decimal_from_longest): Update call. Do not call match_endianness. (decimal_from_ulongest): Likewise. (decimal_binop): Likewise. (decimal_is_zero): Likewise. (decimal_compare): Likewise. (decimal_convert): Likewise. |

GDBserver: Fix ignored Ctrl-C after reconnection
This fixes the issue reported by Dmitry Antipov <dantipov@nvidia.com>
here:
https://sourceware.org/ml/gdb/2017-10/msg00048.html
The problem is that GDBserver stops listening to Ctrl-C/interrupt
requests if you disconnect and reconnect back.
Dmitry wrote:
~~~
Currently gdbserver installs SIGIO handler just once, in
initialize_async_io() called from captured_main(), and this handler is
removed when remote_desc is closed in remote_close(). Next, when a
new instance of remote_desc is fetched from accept() and has '\003'
arrived, input_interrupt() is never called because it is not
registered as SIGIO handler.
~~~
The fix here is not remove the SIGIO handler in the first place, thus
going back to the original before-first-connection state.
(I haven't gone back to try it, but I think this was a regression
caused by commit

Fix gdb.base/starti.exp racy test
This commit fixes a couple problems with gdb.base/starti.exp, causing
spurious FAILs.
The first is a double-prompt problem:
~~~
(gdb) PASS: gdb.base/starti.exp: hook-stop
starti
[....]
gdb_expect_list pattern: /\$1 = 0/
$1 = 0
gdb_expect_list pattern: //
0x00007ffff7ddcc80 in _start () from /lib64/ld-linux-x86-64.so.2
(gdb) # EXPECTED PROMPT
(gdb) PASS: gdb.base/starti.exp: starti # ANOTHER PROMPT!
break main
~~~
This happens because the test uses gdb_test_sequence with no command,
like this:
gdb_test_sequence "" "starti" {
"Program stopped."
"\\$1 = 0"
}
but gdb_test_sequence doesn't have a check for empty command like
gdb_test_multiple does, and so sends "\n" to GDB:
proc gdb_test_sequence { command test_name expected_output_list } {
global gdb_prompt
if { $test_name == "" } {
set test_name $command
}
lappend expected_output_list ""; # implicit ".*" before gdb prompt
send_gdb "$command\n"
return [gdb_expect_list $test_name "$gdb_prompt $" $expected_output_list]
}
"starti" is a no-repeat command, so pressing <ret> just makes another
prompt appear, confusing the following gdb_test/gdb_test_multiple/etc.
Even with that fixed, the testcase is still racy though.
The second problem is that sometimes the "continue" test times out
here:
~~~
continue
Continuing.
$2 = 1
gdb_expect_list pattern: /.*Breakpoint .*main \(\) at .*starti.c.*/
Breakpoint 1, main () at /home/pedro/src/gdb/testsuite/gdb.base/starti.c:29
29 return 0;
(gdb) gdb_expect_list pattern: //
* hung here *
~~~
The problem is that the too-greedy ".*" trailing match in
gdb_expect_list's pattern ends up consuming GDB's prompt too soon.
Fix that by removing the unnecessary trailing ".*". While at it,
remove all ".*"s to be stricter.
Tested on x86_64 GNU/Linux.
gdb/testsuite/ChangeLog:
2017-11-16 Pedro Alves <palves@redhat.com>
* gdb.base/starti.exp ("continue" test): Remove ".*"s from
pattern.
* lib/gdb.exp (gdb_test_sequence): Don't send empty command to
GDB.

Fix gdb.tui/completion.exp test
When I run it locally, the test gdb.tui/completion.exp test fails because of a timeout: Running /home/emaisin/src/binutils-gdb/gdb/testsuite/gdb.tui/completion.exp ... FAIL: gdb.tui/completion.exp: completion of layout names: tab completion (timeout) The problem seems to be this regex, which confirms that after doing layout<TAB>, "layout" is printed again after the gdb prompt: -re "^$input_line$" The problem is that there's a trailing space in the output after "layout". Since the regex has an anchored end (the $), it doesn't match. Adding a space fixes the test. gdb/testsuite/ChangeLog: * gdb.tui/completionn.exp (test_tab_completion): Add space in regex. |

Fix 'xfered>0' assertion in target.c for remote connection
We have a customer who is using a Corelis gdb server to connect to gdb. Occasionally, the gdb server will send a 0-byte block of memory for a read. When this happens, gdb gives an assertion from target.c: internal-error: target_xfer_partial: Assertion `*xfered_len > 0' failed. This problem is almost identical to that fixed in https://sourceware.org/ml/gdb-patches/2014-02/msg00636.html In this case, remote.c needs to be modified to return TARGET_XFER_EOF instead of TARGET_XFER_OK or TARGET_XFER_UNAVAILABLE when 0 bytes are transferred. gdb/ChangeLog: PR gdb/22388 * remote.c (remote_write_bytes_aux, remote_read_bytes_1, remote_read_bytes, remote_write_qxfer, remote_xfer_partial): Return TARGET_XFER_EOF if size of returned data is 0. |

local variable watchpoint not deleted after leaving scope
When debugging an Ada program, and inserting a watchpoint tracking
a local variable, the watchpoint doesn't get automatically deleted
upon leaving that variable's scope. This watchpoint then starts
creating problems later on, when trying to resume the program's
execution from a location outside of the watchpoint's scope:
(gdb) c
Continuing.
Breakpoint 2, foo_p708_025 () at foo_p708_025.adb:7
7 Do_Nothing (Val);
(gdb) n
No frame is currently executing in block pck.get_val.
Command aborted.
(gdb) c
Continuing.
No frame is currently executing in block pck.get_val.
Command aborted.
The expected output is the following:
- The program's execution after the first continue should stop
as soon as we reach the end of the watchpoint's scope, and
the debugger should be deleting it.
- Then we can continue until reaching breakpoint 2 above;
- After which we should be able to do next/continue as usual.
The reason the watchpoint is not automatically deleted at scope exit
is because the watchpoint is not marked as being scope-specific
(b->exp_valid_block is equal NULL), and this is because the
symbol lookup for our local variable failed to set the innermost_block
global variable during the lookup.
More precisely, if we look at watch_command_1, we do the following:
innermost_block = NULL;
[...]
exp = parse_exp_1 (&arg, 0, 0, 0);
[...]
exp_valid_block = innermost_block;
Currently, innermost_block stays NULL after the call to parse_exp_1.
Digging further, this innermost_block is typically set during symbol
lookup when the symbol is considered to have a frame-relative address.
For instance, in c-exp.y, we see some code like the following:
if (symbol_read_needs_frame (sym.symbol))
{
if (innermost_block == 0
|| contained_in (sym.block,
innermost_block))
innermost_block = sym.block;
}
We actually have the exact same mechanism in ada-exp.y, except
that it vhas accidently been turned off. See write_var_from_sym,
where we start with:
if (orig_left_context == NULL && symbol_read_needs_frame (sym))
{
if (innermost_block == 0
|| contained_in (block, innermost_block))
innermost_block = block;
}
In this case, orig_left_context is a parameter, and looking at
the point of call in write_var_or_type, we see:
if (nsyms == 1)
{
write_var_from_sym (par_state, block, syms[0].block,
syms[0].symbol);
In the call above, the paramater we are interested in is "block",
which is a parameter for write_var_or_type as well, except we
explicitly override its value at the beginning when found to be NULL:
if (block == NULL)
block = expression_context_block;
So the block we pass to write_var_from_sym is not NULL, and
we therefore don't set innermost_block, which leads to the watchpoint
no longer being marked as scope-specific.
The handling of orig_left_context in write_var_from_sym was there
to handle the case where a user writes an expression where the symbol
is qualified with a scope (Eg: "function::variable"). But it appears
that handling this is specifically here is no longer necessary,
so this patch simply removes that parameter and the associated check,
and then updates all the points of calls.
Interestingly, this also affects GDB/MI, and in particular varobjs,
because local variables are now properly reported as having a block,
which causes the associated varob to have a "thread-id" field.
This patch also adjusts a couple of Ada/gdb-mi tests.
gdb/ChangeLog:
* ada-exp.y (write_var_from_sym): Remove parameter
"orig_left_context". Update all callers.
gdb/testsuite/ChangeLog:
* gdb.ada/scoped_watch: New testcase.
* gdb.ada/watch_arg.exp: Adjust expected behavior to the behavior
which is actually correct.
* gdb.ada/mi_interface.exp: Add missing thread-id in expected varobj.
* gdb.ada/mi_var_array.exp: Add missing thread-id in expected varobj.

The problem is that we're always computing the arguments to pass to
complaint, including passing the format strings through gettext, even
when complaints are disabled. As seen above, gettext can be quite
expensive.
Fix this by wrapping complaint in a macro that skips the real
complaint call when complaints are disabled.
This improves "gdb -nx -readnow -batch gdb" from
~11.0s => ~7.8s with -O2 -g3, and
~6.0s => ~5.3s with -O2 -g.

Add test for fetching TLS from core file
A correct PID is needed by `libthread_db' library supplied with
glibc repository revisions before commit c579f48edba8 ("Remove
cached PID/TID in clone") or versions before 2.25 release for
GDB to fetch value of TLS variable from core file. On MIPS
platforms it was omitted and fetching value of TLS variable was not
available.
This adds a new test in order to be sure if GDB on native platforms
can successfully fetch value of TLS variable.

Use search_domain::FUNCTIONS_DOMAIN when setting breakpoints
While working on C++ support for wild matching, I noticed that
attaching to my system's Firefox (which uses .gdb_index), setting a
break at main and bailing, like:
$ gdb --batch -q -p `pidof firefox` -ex "b main"
would get substancially slower. It'd take around 20s when currently
it takes 3s.
The problem is that gdb would expand more symtabs than currently,
because Firefox has symbols named like "nsHtml5Atoms::main",
"nsGkAtoms::main", etc., which given wild matching, match.
However, these are not function symbols, [they're "(nsIAtom *)"], so
it seems silly that they'd cause expansion in the first place.
The .gdb_index code (dwarf2read.c:dw2_expand_marked_cus) filters out
symbols matches based on search_domain:
case VARIABLES_DOMAIN:
if (symbol_kind != GDB_INDEX_SYMBOL_KIND_VARIABLE)
continue;
break;
case FUNCTIONS_DOMAIN:
if (symbol_kind != GDB_INDEX_SYMBOL_KIND_FUNCTION)
continue;
break;
case TYPES_DOMAIN:
if (symbol_kind != GDB_INDEX_SYMBOL_KIND_TYPE)
continue;
break;
default:
break;
however, we're currently passing down search_domain::ALL_DOMAIN when
we know we're looking for functions, for no good reason. This patch
fixes that.
It seems like search_domain is underutilized throughout, but I'll
leave using it more for another pass.

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

Optimize .gdb_index symbol name searching
As mentioned in the previous patch, .gdb_index name lookup got significantly slower with the previous patch. This patch addresses that, and in the process makes .gdb_index name searching faster than what we had before the previous patch, even. Using the same test: $ 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.cmd" I got, before the previous patch (-O2, x86-64): real 0m1.773s user 0m1.737s sys 0m0.040s and after this patch: real 0m1.361s user 0m1.315s sys 0m0.040s The basic idea here is simple: instead of always iterating over all the symbol names in the index, we build an accelerator/sorted name table and binary search names in it. Later in the series, we'll want to support wild matching for C++ too, so this mechanism already considers that. For example, say that you're looking up functions/methods named "func", no matter the containing namespace/class. If we sorted the table by qualified name, then we obviously wouldn't be able to find those symbols with a binary search: func ns1:🅰️🅱️:func ns1:🅱️:func ns2::func (function symbol names in .gdb_index have no parameter info, like psymbols) To address that out, we put an entry for each name component in the sorted table. something like this: Table Entry Actual symbol --------------------------------- func func func ns1:🅰️🅱️:func b::func ns1:🅰️🅱️:func a:🅱️:func ns1:🅰️🅱️:func ns1:🅰️🅱️:func ns1:🅰️🅱️:func func ns1:🅱️:func b::func ns1:🅱️:func ns1:🅱️:func ns1:🅱️:func func ns2::func ns2::func ns2::func Which sorted results in this: Table Entry Actual symbol --------------------------------- a:🅱️:func ns1:🅰️🅱️:func b::func ns1:🅰️🅱️:func b::func ns1:🅱️:func func func func ns1:🅰️🅱️:func func ns1:🅱️:func func ns2::func ns1:🅰️🅱️:func ns1:🅰️🅱️:func ns1:🅱️:func ns1:🅱️:func ns2::func ns2::func And we can binary search this. Note that a binary search approach works for both completion and regular lookup, while a name hashing approach only works for normal symbol looking, since obviously "fun" and "func" have different hashes. At first I was a bit wary of these tables potentially growing GDB's memory significantly. But I did an experiment that convinced it's not a worry at all. I hacked gdb to count the total number of entries in all the tables, attached that gdb to my system/Fedora's Firefox (Fedora's debug packages uses .gdb_index), did "set max-completions unlimited", and then hit "b [TAB]" to cause everything to expand. That resulted in |

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 gdb/ChangeLog: 2017-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_encode): Rename to ..

Per-language symbol name hashing algorithm
Currently, we have a mess of symbol name hashing/comparison routines. There's msymbol_hash for mangled names, and dict_hash and msymbol_hash_iw for demangled names. Then there's strcmp_iw, strcmp_iw_ordered and Ada's full_match/wild_match, which all have to agree with the hashing routines. That's why dict_hash is really about Ada names. From the inconsistency department, minimal symbol hashing doesn't go via dict_hash, so Ada's wild matching can't ever work with minimal symbols. This patch starts fixing this, by doing two things: #1 - adds a language vector method to let each language decide how to compute a symbol name hash. #2 - makes dictionaries know the language of the symbols they hold, and then use the dictionaries language to decide which hashing method to use. For now, this is just scaffolding, since all languages install the default method. The series will make C++ install its own hashing method later on, and will add per-language symbol name comparison routines too. This patch was originally based on a patch that Keith wrote for the libcc1/C++ WIP support. gdb/ChangeLog: 2017-11-08 Keith Seitz <keiths@redhat.com> Pedro Alves <palves@redhat.com> * ada-lang.c (ada_language_defn): Install default_search_name_hash. * buildsym.c (struct buildsym_compunit): <language>: New field.

These overloads will be removed when add_info is constified. gdb/ChangeLog 2017-11-07 Tom Tromey <tom@tromey.com> * solib.h (no_shared_libraries): Constify. * frame.h (return_command): Constify. * cli/cli-cmds.h (quit_command): Constify. * top.h (quit_command, execute_command): Constify. * target.h (flash_erase_command): Constify. * inferior.h (set_inferior_args, attach_command): Constify. * tracepoint.h (start_tracing, stop_tracing): Constify. * breakpoint.h (break_command, tbreak_command) (hbreak_command_wrapper, thbreak_command_wrapper) (rbreak_command_wrapper, watch_command_wrapper) (awatch_command_wrapper, rwatch_command_wrapper) (get_tracepoint_by_number): Constify. * symtab.c (info_variables_command, rbreak_command) (symtab_symbol_info): Constify.

Add set_repeat_arguments function
The "x", "list", and "show commands" commands have special repetition behavior: repeating the command doesn't re-run it with the same arguments This is currently implemented by modifying the passed-in argument; but that won't work properly with const arguments (and seems pretty obscure besides). This patch adds a new "set_repeat_arguments" function and changes the relevant places to call it. gdb/ChangeLog 2017-11-07 Tom Tromey <tom@tromey.com> * printcmd.c (x_command): Call set_repeat_arguments. * cli/cli-cmds.c (list_command): Call set_repeat_arguments. * top.c (repeat_arguments): New global. (set_repeat_arguments): New function. (execute_command): Handle repeat_arguments. (show_commands): Calls set_repeat_arguments. * command.h (set_repeat_arguments): Declare. |
