Before commit 70ee000084aa ("[gdb] Allow function arguments in bp
print match in selftest_setup"), this pattern in selftest_setup:
-re "Starting program.*Breakpoint \[0-9\]+,.* at .*main.c:.*$function.*$gdb_prompt $" {
# $function may be inlined, so the program stops at the line
# calling $function.
pass "$description"
}
happened to match if captured_main_1 was inlined and captured_main was
not, because captured_main calls captured_main_1 first thing, which
coincidentally matches "$function.*":
Breakpoint 1, captured_main (data=<optimized out>) at src/gdb/main.c:1147
1147 captured_main_1 (context);
That would probably be better "$function .*", with a space, but I
think that even better is to remove the "may be inlined" case too now,
because since ddfe970e6bec ("Don't elide all inlined frames") GDB
presents the stop at the inline function instead of at the caller.

This adds a "continue" response to the pager. If the user types "c"
in response to the pager prompt, pagination will be disabled for the
duration of one command -- but re-enabled afterward. This is handy if
you type a command that produces a lot of output, and you don't want
to baby-sit it by typing "return" each time the prompt comes up.
Tested by the buildbot.

When $use_gdb_stub is true then, when we start an MI target there's a
regexp to match GDB's startup pattern. Unfortunately the pattern is
broken, and we're also missing a timeout case in the match list (which
would have helped point out that the regexp was broken).
The changes to the regexp are:
1. Remove '${run_match}' prefix, the issued command doesn't include
'${run_prefix}' so expecting '${run_match}' is wrong.
2. Replaced '\\n' with '\\\\n' in order to match literal '\n' in
GDBs output (that is, match a backslash followed by 'n', not a
newline character).
3. Replaced a '.' (matching any character) with '\.' to match a '.'
and moved the '\.' into the correct place in the regexp.
4. Replaced '\r\n' with '[\r\n]+' to match the end of a line. This
change isn't esential, but matches the other end of line patterns
within this regexp.
Here's an example of the output that the regexp should match taken
from a testfile log, the first line is the command sent to GDB, and
the remaining lines are the response from GDB:
jump *_start
&"jump *_start\n"
~"Continuing at 0x10074.\n"
^running
*running,thread-id="all"
(gdb)

In the GDB test suite, there are still multiple invocations of

Simon mentioned on IRC that, after the startup-with-shell feature has
been implemented on gdbserver, it is not possible to specify a
filename-only binary, like:
$ gdbserver :1234 a.out
/bin/bash: line 0: exec: a.out: not found
During startup program exited with code 127.
Exiting
This happens on systems where the current directory "." is not listed
in the PATH environment variable. Although including "." in the PATH
variable is a possible workaround, this can be considered a regression
because before startup-with-shell it was possible to use only the
filename (due to reason that gdbserver used "exec*" directly).
The idea of the patch is to verify if the program path provided by the
user (or by the remote protocol) contains a directory separator
character. If it doesn't, it means we're dealing with a filename-only
binary, so we call "gdb_abspath" to properly expand it and transform
it into a full path. Otherwise, we leave the program path untouched.
This mimicks the behaviour seen on GDB (look at "openp" and
"attach_inferior", for example).
I am also submitting a testcase which exercises the scenario described
above. This test requires gdbserver to be executed in a different CWD
than the original, so I also created a helper function, "with_cwd" (on
testsuite/lib/gdb.exp), which takes care of cd'ing into and out of the
specified dir.
Built and regtested on BuildBot, without regressions.

I removed gdb_is_target_remote_prompt, but did not realize it was used

I noticed some failures of some buildbot slaves, e.g.:
FAIL: gdb.cp/nested-types.exp: ptype S10 (limit = 1) // wrong nested type enum definition: enum S10::E10 {S10::A10, S10::B10, S10::C10};
The issue is that they have an older gcc (not c++11 by default?) that
doesn't emit the enum underlying type information. When the
enum type is printed by ptype, it looks like this:
enum S10::E10 {S10::A10, S10::B10, S10::C10};
instead of this on older gccs:
enum S10::E10 : unsigned int {S10::A10, S10::B10, S10::C10};
The regex that matches this is in cp_test_ptype_class, and is
enum $nested_name (: (unsigned )?int)? \{
If the "unsigned int" portion is not present, then it requires the
string to have two spaces between the enum name and opening bracket.
The fix is simply to move the trailing space inside the ? group.
gdb/testsuite/ChangeLog:
* lib/cp-support.exp (cp_test_ptype_class): Move space inside
parentheses.

In August 2017 the GDB test suite was changed to always add the compile
option "-fdiagnostics-color=never", see:
https://sourceware.org/ml/gdb-patches/2017-08/msg00150.html
Since this option is not understood by rustc, a commit from 09/2017
dropped its use in that case:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=5eb5f850
("Don't use -fdiagnostics-color=never for rustc")
But that change goes overboard and stops using the option for other
languages as well. Thus compiler diagnostics written into gdb.log may
contain colored output again. This is fixed.

* lib/gdb.exp (gdb_compile): Re-enable use of

Trying to use gdb_compile_shlib with the shlib= option to build a shared
library that depends on another shared library does not work as of
today. See:
https://sourceware.org/ml/gdb-patches/2017-10/msg00733.html
The problem is that building the lib is done in two steps, compilation
(.c -> .o) and linking (.o -> .so) and the shlib= options are passed to
both steps. When compiling the object file (.o), it results in gcc
complaining:
gcc: warning: .../solib-vanish-lib2.so: linker input file unused because linking not done
The first solution I came up with was to filter the options inside
gdb_compile_shlib to remove the shlib= options from the options we pass
when compiling the .o file.
I then thought it would be simpler to ignore the shlib= options in
gdb_compile when not building an executable (the executable category
includes the shared libraries). For other compilation types (object
file, preprocess and generate assembly), it doesn't make sense to add
shared libraries to the source file list.
Regtested on the buildbot.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (gdb_compile): Ignore shlib= and shlib_load
options when not creating an executable.

While writing the tests included in the previous commit, I noticed
that test_gdb_complete_tab_multiple would not FAIL if GDB happens to
show more completions than expected before the expected list.
E.g., with something like this, expecting "p foo" to complete to
"foo2" and "foo3":
test_gdb_complete_tab_multiple "p foo" "" {
"foo2"
"foo3"
}
and then if foo actually completes to:
(gdb) p foo[TAB]
foo1 foo2 foo3
^^^^
we'd still PASS. (Note the spurious "foo1" above.)
This tightens the regexp with a beginning anchor thus making the
completions above cause a FAIL. Other similar functions in
completion-support.exp already do something like this; I had just
missed this one originally. Thankfully, this did not expose any
problems in the gdb.linespec/ tests. Phew.

I noticed this regression in the expression completer:
"(gdb) p std::[TAB]" => "(gdb) p std::std::"
obviously we should have not completed to "std::std::".
The problem is that in the earlier big completer rework, I missed
taking into account the fact that with expressions, the completion
word point is not always at the start of the symbol name (it is with
linespecs).
The fix is to run the common prefix / LCD string (what readline uses
to expand the input line) through make_completion_match_str too.
New testcase included, exercising both TAB completion and the complete
command.

GDB currently does not track types defined in classes. Consider:
class A
{
public:
class B
{
public:
class C { };
};
};
(gdb) ptype A
type = class A {
<no data fields>
}
This patch changes this behavior so that GDB records these nested types
and displays them to the user when he has set the (new) "print type"
option "nested-type-limit."
Example:
(gdb) set print type nested-type-limit 1
(gdb) ptype A
type = class A {
<no data fields>
class A::B {
<no data fields>
};
}
(gdb) set print type nested-type-limit 2
type = class A {
<no data fields>
class A::B {
<no data fields>
class A::B::C {
<no data fields>
};
};
}
By default, the code maintains the status quo, that is, it will not print
any nested type definitions at all.
Testing is carried out via cp_ptype_class which required quite a bit of
modification to permit recursive calling (for the nested types). This
was most easily facilitated by turning the ptype command output into a
queue. Upshot: the test suite now has stack and queue data structures that
may be used by test writers.

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.

This exercises the special handling C++ operators require in several
places in the linespec parser, both the linespec and explicit location
completers, symbol lookup, etc. Particularly, makes sure all that
works without quoting.
Note that despite the apparent smallish size, this adds thousands of
tests to the testsuite, due to combination explosion (linespecs,
explicit locations, tab completion, complete command, completion at
different points in each function, etc.)

Exercises all sorts of aspects fixed by previous patches, going back a
few months.
- Exercises label completion, linespecs and explicit locations.
- Exercises both quoting vs non-quoting, source filenames, function
names, labels, with both linespecs and explicit locations.
- Tests corner cases around not-quoting function names, and
whitespace and/and completing inside a parameter or template
argument list, anonymous namespace awareness, etc.
E.g.,
"break foo<[TAB]" -> "break foo<int>()"
"break bar ( int[TAB]" -> "break bar ( int)
"break ( anon" -> "break ( anonymous namespace)::func()"
"b cfunc() [tab]" -> "b cfunc() const"
"b rettype templfunc[tab]" -> "b rettype templfunc<bar>()"
... and others.
- Tests the "b source.c[TAB] -> b source.cc:" feature. I.e., colon
auto-appending.
- Exercises corner cases around C++ "operator<" / "operator<<".
(Much more extensive C++ operator completion/linespec handling in a
separate patch.)
- Exercises both tab completion and "complete" command completion,
using routines that handle it automatically, to ensure no test
forgets either mode.
- Many of the completion tests test completion at at prefix of a
given tricky name, to make sure all corner cases are covered.
E.g., completing before, at and after ":", "(", "<".
- Exercises "keyword" completion. I.e., "b function() [TAB]"
displaying "if task thread" as completion match list. Likewise for
display explicit location options matches at the appropriate
points.
- Ensures that the completer finds the same breakpoint locations that
setting a breakpoint finds.
- Tests that linespec/location completion doesn't find data symbols.
- Tests that expression completion still kicks in after a
linespec/location keyword. I.e., this:
"b function () if global1 + global[TAB]"
knows that after "if", you're completing on an expression, and thus
breaks words after "if" as an expression and matches on "global" as
a data symbol.
- Adds common routines to help with all the above, to be used by
multiple completion and linespec/location test cases.
- More...

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

Currently, if you diff testsuite/gdb.sum of different builds you see
this spurious hunk:
-PASS: gdb.python/py-objfile.exp: get python valueof "sep_objfile.build_id" (6a0bfcab663f9810ccff33c756afdebb940037d4)
+PASS: gdb.python/py-objfile.exp: get python valueof "sep_objfile.build_id" (1f5531c657c57777b05fc95baa0025fd1d115c3b)
Fix this by syncing get_python_valueof with get_integer_valueof, which
stopped outputting the value in commit 2f20e312aad6
("get_integer_valueof: Don't output value in test name").
After this commit we'll show:
PASS: gdb.python/py-objfile.exp: get python valueof "sep_objfile.build_id"
As the comment explicitly says get_python_valueof is modeled on
get_integer_valueof, I went ahead and also added the optional 'test'
parameter while at it.
gdb/testsuite/ChangeLog:
2017-10-24 Pedro Alves <palves@redhat.com>
* lib/gdb-python.exp (get_python_valueof): Add 'test' optional
parameter and handle it. Don't output read value in test name.

|
These tests want to use raw "run", so skip them on targets that can't
do that.
Also adds a small utility procedure that clearly conveys intent instead of
explicitly checking use_gdb_stub in the testcases.
This makes sure these testcases continue to be skipped with
--target_board=native-gdbserver once that board stops setting
is_remote.

If we make the native-gdbserver board be !is_remote, then the few
tests that use the selftest-support.exp routines to debug gdb itself
start running, and fail, with something like:
Running ..../src/gdb/testsuite/gdb.gdb/selftest.exp ...
ERROR: tcl error sourcing ..../src/gdb/testsuite/gdb.gdb/selftest.exp.
ERROR: gdbserver does not support run [....] without extended-remote

invoked from within
"gdb_test_multiple "run $INTERNAL_GDBFLAGS" "$description" {
-re "Starting program.*Breakpoint \[0-9\]+,.*$function \\(\\).* at .*main.c:.*$gdb..."
(procedure "selftest_setup" line 45)
This commit makes sure those tests continue to be skipped.
gdb/testsuite/ChangeLog:
2017-10-13 Pedro Alves <palves@redhat.com>
* lib/selftest-support.exp (selftest_setup): Extend comments, and
also skip on stub-like targets.

The get_integer_valueof outputs the value it has read as part of the
test name. This causes test names to vary from run to run, and adds
some noise when diffing test results. e.g.:
-PASS: gdb.threads/process-dies-while-detaching.exp: multi-process: continue: killed outside: get integer valueof "mypid" (28770)
+PASS: gdb.threads/process-dies-while-detaching.exp: multi-process: continue: killed outside: get integer valueof "mypid" (32238)
This patch removes that, since it's probably not very useful.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (get_integer_valueof): Don't output read value in test name.

If you want to use catch_errors with a function with parameters, then
currently you have to manually write a "capture" struct wrapping the
arguments and marshall/unmarshall that.
https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed
adjusting catch_errors to use gdb::function_view, which would allow
passing lambdas with automatic captures. However, it seems like using
TRY/CATCH directly instead ends up producing clearer and easier to
debug code. This is what this commit does.
Note that removing catch_errors exposes further cleanup opportunities
around no longer having to follow catch_errors callback type, and also
removes a few cleanups.
I didn't do anything to save/restore current_uiout because I think
that should be the responsibility of the code that changes
current_uiout in the first place.
(Another approach could be to make catch_errors a variadic template
like:
template<typename Function, typename... Args>
int catch_errors (const char *errstring, return_mask mask,
Function &&func, Args... args);
and then with:
extern void function_with_args (int, int);
extern void function_with_no_args ();
calls to the above functions would be wrapped like this:
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_args, arg1, arg2);
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_no_args);
but I'm thinking that that doesn't improve much if at all either.)

This works like 'start' but it stops at the first instruction rather
than the first line in main(). This is useful if one wants to single

I noticed that the gdb.rust tests fail because the test suite passes
-fdiagnostics-color=never to rustc. This is not a recognized rustc
option, and the test suite already handles passing the appropriate
option to the Rust compiler.

Newer GCC versions yield colored diagnostic messages by default, which may
be useful when executing GDB interactively from a terminal. But when run
from a GDB test case, the compiler output is written into gdb.log, where
such escape sequences are usually more inhibiting than helpful to the
evaluation of test results. So this patch suppresses that.

The get_valueof procedure allows tests to conveniently make gdb evaluate
an expression an return the value as a string. However, it includes an
end-of-line character in its result. I stumbled on this when trying to
use that result as part of a regex further in a test.
You can see this for example by adding a puts in
gdb.dwarf2/implref-struct.exp:get_members:
set members [get_valueof "" ${var} ""]
puts "<$members>"
The output is
<{a = 0, b = 1, c = 2}
>
This is because the regex in get_valueof is too greedy, the captured
portion matches anything up to the gdb_prompt, including the end of line
characters. This patch changes it to capture everything but end of line
characters.
The output of the puts becomes:
<{a = 0, b = 1, c = 2}>
I tested this by running gdb.dwarf2/implref-array.exp and
gdb.dwarf2/implref-struct.exp, the two only current users of that
procedure.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (get_valueof): Don't capture end-of-line
characters.

This is the portion of gdb_test which performs the match against
the RE (regular expression) passed to it:
return [gdb_test_multiple $command $message {
-re "\[\r\n\]*($pattern)\[\r\n\]+$gdb_prompt $" {
if ![string match "" $message] then {
pass "$message"
}
}
In a test that I've been working on recently, I wanted to use
a backreference - that's the \1 in the the RE below:
gdb_test "info threads" \
{.*[\r\n]+\* +([0-9]+) +Thread[^\r\n]* do_something \(n=\1\) at.*}
Put into English, I wanted to make sure that the value of n passed to
do_something() is the same as the thread number shown in the "info
threads" Id column. (I've structured the test case so that this
*should* be the case.)
It didn't work though. It turned out that ($pattern) in the RE
noted above is capturing the attempted backreference. So, in this
case, the backreference does not refer to ([0-9]+) as intended, but
instead refers to ($pattern). This is wrong because it's not what I
intended, but is also wrong because, if allowed, it could only match a
string of infinite length.
This problem can be fixed by using parens for a "noncapturing
subpattern". The way that this is done, syntactically, is to use
(?:$pattern) instead of ($pattern).
My research shows that this feature has been present since tcl8.1 which
was released in 1999.
The current tcl version is 8.6 - at least that's what I have on my
machine. It appears to me that mingw uses some subversion of tcl8.4
which will also have this feature (since 8.4 > 8.1).
So it seems to me that any platform upon which we might wish to test
GDB will have a version of tcl which has this feature. That being the
case, my hope is that there won't be any objections to its use.
When I looked at the implementation of gdb_test, I wondered whether
the parens were needed at all. I've concluded that they are. In the
event that $pattern is an RE which uses alternation at the top level,
e.g. a|b, we need to make $pattern a subpattern (via parens) to limit
the extend of the alternation. I.e, we don't want the alternation to
extend to the other portions of the RE which gdb_test uses to match
potential blank lines at the beginning of the pattern or the gdb
prompt at the end.
gdb/testsuite/ChangeLog:
* gdb.exp (gdb_test): Using noncapturing parens for the $pattern
subpattern.

DWARF locations. It uses register- and memory locations and composite
locations with register- and memory pieces.
Since the new test calls gdb_test_no_output with commands that contain
braces, it is necessary for string_to_regexp to quote braces as well.
This was not done before.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/var-access.c: New file.
* gdb.dwarf2/var-access.exp: New test.
* lib/gdb-utils.exp (string_to_regexp): Quote braces as well.

This patch fixes an internal error exposed by a test that does
something like:
define kill-and-remove
kill inferiors 2
remove-inferiors 2
end
# Start one inferior.
start
# Start another inferior.
add-inferior 2
inferior 2
start
# Kill and remove inferior 1 while inferior 2 is selected.
thread apply 1.1 kill-and-remove
The internal error looks like this:
Thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677)):
[Switching to inferior 1 [process 20677] (gdb/testsuite/outputs/gdb.threads/threadapply/threadapply)]
[Switching to thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677))]
#0 main () at src/gdb/testsuite/gdb.threads/threadapply.c:38
38 for (i = 0; i < NUM; i++)
src/gdb/inferior.c:66: internal-error: void set_current_inferior(inferior*): Assertion `inf != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/threadapply.exp: kill_and_remove_inferior: try kill-and-remove: thread apply 1.1 kill-and-remove (GDB internal error)
There are several problems around this area of the code. One is that
in do_restore_current_thread_cleanup, we do a look up of inferior by
ptid, which can find the wrong inferior if the previously selected
inferior exited and some other inferior was started with a reused pid
(rare, but still...).
The other problem is that the "remove-inferiors" command rejects
attempts to remove the current inferior, but when we get to
"remove-inferiors" in a "thread apply THR remove-inferiors 2" command,
the current inferior is the inferior of thread THR, not the previously
selected inferior, so if the previously selected inferior was inferior
2, that command still manages to wipe it, and then gdb restores the
old selected inferior, which is now a dangling pointer...
So the fix here is:
- Make make_cleanup_restore_current_thread store a pointer to the
previously selected inferior directly, and use it directly instead
of doing ptid look ups.
- Add a refcount to inferiors, very similar to thread_info's refcount,
that is incremented/decremented by
make_cleanup_restore_current_thread, and checked before deleting an
inferior. To avoid duplication, a new refcounted_object type is
added, that both thread_info and inferior inherit from.

When using mi_gdb_test, if it fails because of the presence of
unexpected output, the error message is only the message passed as
the argument with no indication that there was an unexpected output.
This change adds an additional text to the failure message to

Recently I fixed a bug that caused a DW_OP_implicit_pointer with non-zero
offset into a DW_OP_implicit_value to be handled incorrectly on big-endian
targets. GDB ignored the offset and copied the wrong bytes:
https://sourceware.org/ml/gdb-patches/2017-01/msg00251.html
But there is still a similar issue when a DW_OP_implicit_pointer points
into a DW_OP_stack_value instead; and again, the offset is ignored. There
is an important difference, though: While implicit values are treated like
blocks of data and anchored at the lowest-addressed byte, stack values
traditionally contain integer numbers and are anchored at the *least
significant* byte. Also, stack values do not come in varying sizes, but
are cut down appropriately when used. Thus, on big-endian targets the
scenario looks like this (higher addresses shown right):
|<- - - - - Stack value - - - - - - ->|
| |
|<- original object ->|
|
| offset ->|####|
^^^^
de-referenced
implicit pointer
(Note how the original object's size influences the position of the
de-referenced implicit pointer within the stack value. This is not the
case for little-endian targets, where the original object starts at offset
zero within the stack value.)
This patch implements the logic indicated in the above diagram and adds an
appropriate test case. A new function dwarf2_fetch_die_type_sect_off is
added; it is used for retrieving the original object's type, so its size
can be determined. That type is passed to dwarf2_evaluate_loc_desc_full
via a new parameter.
gdb/ChangeLog:
* dwarf2loc.c (indirect_synthetic_pointer): Get data type of
pointed-to DIE and pass it to dwarf2_evaluate_loc_desc_full.
(dwarf2_evaluate_loc_desc_full): New parameter subobj_type; rename
byte_offset to subobj_byte_offset. Fix the handling of
DWARF_VALUE_STACK on big-endian targets when coming via an
implicit pointer.
(dwarf2_evaluate_loc_desc): Adjust call to
dwarf2_evaluate_loc_desc_full.
* dwarf2loc.h (dwarf2_fetch_die_type_sect_off): New declaration.
* dwarf2read.c (dwarf2_fetch_die_type_sect_off): New function.
gdb/testsuite/ChangeLog:
* lib/dwarf.exp: Add support for DW_OP_implicit_pointer.
* gdb.dwarf2/nonvar-access.exp: Add test for stack value location
and implicit pointer into such a location.

An optional parameter TEST has been added to get_hexadecimal_valueof in commit:
https://sourceware.org/ml/gdb-patches/2016-06/msg00469.html
This patch adds a similar optional parameter to other related methods that
retrieve expression values: get_valueof, get_integer_valueof and get_sizeof.
Thus tests that evaluate same expression multiple times can provide custom
test names, ensuring that test names will be unique.
gdb/testsuite/ChangeLog:
2017-03-14 Anton Kolesov <anton.kolesov@synopsys.com>

The next patch will require checking the DejaGnu version. There is
already a test that does this,
gdb.threads/attach-many-short-lived-threads.exp. This patch introduces
a new procedure, dejagnu_version, and makes that test use it.
The version number is "right-padded" with zeroes, to make sure that we
always return a triplet (major, minor, patch).
The procedure does not consider the DejaGnu versions from git. For
example, if you used DejaGnu from its current master branch, the version
would be "1.6.1-git", meaning that 1.6.1 will be the next release. I
figured we'll cross that bridge when (and if) we get there.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (dejagnu_version): New proc.
* gdb.threads/attach-many-short-lived-threads.exp (bad_dejagnu):
Use dejagnu_version.

DWARF-5 has new form DW_FORM_data16. The problem is that GDB cannot pass
16-byte constant as a constant value as that would require GDB to use GCC
extension __int128.
Formerly such data was coded as DW_FORM_block* so GDB still decodes
DW_FORM_data16 like DW_FORM_block*.

Exercising aarch64-elf with a custom debug stub i noticed a few failures in

FAIL: gdb.base/memattr.exp: mem 2-4 were deleted
These failures don't show up with gdbserver or native gdb on Linux because
they don't export any memory maps, therefore the vector of memory regions is
empty.
Outside of that scenario, we can't guarantee the absence of memory regions
reported by the target upon a connection. In our particular target, we
provide a memory map and the memory regions vector ceases to be empty.
With a non-empty memory regions vector, manipulating memory regions will cause
gdb to be more verbose and output text. For example:
memattr.c:require_user_regions
/* Otherwise, let the user know how to get back. */
if (from_tty)
warning (_("Switching to manual control of memory regions; use "
"\"mem auto\" to fetch regions from the target again."));
memattr.c:create_mem_region
if ((lo >= n->lo && (lo < n->hi || n->hi == 0))
|| (hi > n->lo && (hi <= n->hi || n->hi == 0))
|| (lo <= n->lo && ((hi >= n->hi && n->hi != 0) || hi == 0)))
{
printf_unfiltered (_("overlapping memory region\n"));
return;
}
In my particular case i got both of the above messages.
In order to fix this, i've moved the delete_memory proc from
gdb.base/memattr.exp to a new file lib/memory.exp and made lib/gdb.exp
load that file.
For both gdb.base/breakpoint-in-ro-region.exp and gdb.base/memattr.exp the
patch clears all existing memory regions after running to main. That way we
are guaranteed to have a clean state for memory regions so the tests can
exercise whatever they want and have an expected output pattern.

This patch adds a DW_OP_implicit_value in dwarf assembler, and uses
dwarf assembler in implptr-64bit.exp. Using dwarf assembler in
implptr-64bit.exp exposes some limitations in dwarf assembler,
- some variables are not evaluated in the caller's context, so we
can not pass variable to assembler, like this
Dwarf::assemble $asm_file {
cu {
version $dwarf_version
addr_size $addr_size
is_64 $is_64
} {
}
and
{DW_AT_type :$struct_label "DW_FORM_ref$ref_addr_size"}
this limitation is fixed by adding "uplevel" and "subst".
- dwarf assembler doesn't emit DW_FORM_ref_addr for label referencing.
this limitation is fixed by adding a new character "%",
{ type %$int_label }
this means we want to emit DW_FORM_ref_addr for label referencing.
- we can't set the form of label referencing offset in dwarf assembler.
Nowadays, dwarf assembler guesses the form of labels, which is
DW_FORM_ref4. However, in implptr-64bit.exp, both DW_FORM_ref4
and DW_FORM_ref8 is used (see REF_ADDR in implptr-64bit.S). This
patch adds the flexibility of setting the form of label reference.
Both of them below are valid,
{DW_AT_type :$struct_label}
{DW_AT_type :$struct_label DW_FORM_ref8}
the former form is the default DW_FORM_ref4.
I compared the .debug_info of objects without and with this patch
applied. There is no changes except abbrev numbers.

DW_OP_GNU_implicit_pointer refers to a DIE with an offset of different
sizes in different dwarf versions. In v2, the size is the pointer size,
while in v3 and above, it is the ref_addr size. This patch fixes
dwarf assembler to emit the correct size of offset. We've already fixed
this size issue in gdb,

Changes in v2:
- Addressed comments from reviewers.
- Fixed spurious whitespaces.
- Changed compilation failure messages that included source/binary paths to
ones that are short and deterministic.

The following patch is based on the previous patch i sent and handles cases of
test names that start with an uppercase letter. Test names should start with
lowercase unless it starts with the name of a technology, architecture, ISA
etc.
This first patch addresses cases of test names output explicitly via xfail,
kfail, kpass, fail, pass, unsupported, untested and also names set with the
pattern "set test" and "set testname".

- Use multi_line for matching multi-line GDB output.
- Add a multi_line_input variant of multi_line to build GDB input and
use it throughout.
(The two changes above make the tests much more readable, IMO.)
- Add a new valnum_re global to get rid of the multiple "\\\$\[0-9\]*".
- Remove gdb_stop_suppressing_tests uses.
- tighten a few regexps.
- Replace send_gdb/gdb_expect with gdb_test_multiple and simplify,
making pass/fail messages the same.
