Test-case gdb.base/gdb-caching-proc.exp tests whether procs declared using
gdb_caching_proc give the same results when called more than once.
While this tests consistency of the procs in the context of that test-case, it
doesn't test consistency across the call sites.
Add a local variable cache_verify to proc gdb_do_cache, that can be set to 1
to verify gdb_caching_proc consistency across the call sites.
Likewise, add a local variable cache_verify_proc to set to the name of the
gdb_caching_proc to verify. This can f.i. be used when changing an existing
proc into a gdb_caching_proc.
Tested on x86_64-linux, with cache_verify set to both 0 and 1.

* lib/cache.exp (gdb_do_cache): Add and handle local variables
cache_verify and cache_verify_proc.

Fix this by using a new gdb_caching_proc supports_statement_frontiers.
Tested on x86_64-linux, with gcc 7.5.0 (which does not support
-gstatement-frontiers) and with gcc 8.4.0 (which does support

With test-case gdb.tui/corefile-run.exp and make target check-read1, I run
into:
...
FAIL: gdb.tui/corefile-run.exp: run until the end
...
In more detail, using -v:
...

FAIL: gdb.tui/corefile-run.exp: run until the end
...
With some debugging code added in wait_for, what happens becomes more clear:
...
if {[regexp -- $wait_for $prev]} {
+ verbose -log "\nwait_for: MATCHED line ($_cur_y): \"$prev\""
+ verbose -log "wait_for: AGAINST regexp: \"$wait_for\""
...
In corefile-run.exp, we execute:
...
Term::command "run"
...
and in proc Term::command, we send the command, and then call wait_for:
...
proc command {cmd} {
send_gdb "$cmd\n"
wait_for [string_to_regexp $cmd]
}
...
which first waits for the command string, and then for the prompt.
In this case however, the matching of the command string triggers on a
previous line:
...
wait_for: MATCHED line (16): \
"(gdb) core-file corefile-run.core[New LWP 6426] <lots-of-spaces>"
wait_for: AGAINST regexp: "run"
...
and from there on things go out of sync, eventually resulting in the FAIL.
Fix this in proc command by more precisely specifying the expected pattern:
adding a ^$gdb_prompt prefix.
Add a command_no_prompt_prefix variant to use for initial terminal commands
where there's no prompt yet.
Tested gdb.tui/*.exp on x86_64-linux, with make target check and check-read1.

In commit 1281424ccf "[gdb/testsuite] Fix core file load FAIL in
tls-core.exp", I've made this change:
...
- -re ": No such file or directory.*\r\n$gdb_prompt $" {
+ -re "$core: No such file or directory.*\r\n$gdb_prompt $" {
...
However, the $core variable contains a filename which needs to be matched
as a literal string, not as a regexp.
Fix this by using string_to_regexp.

After deinstalling package glibc-debugsource, I run into the following FAIL
with test-case gdb.threads/tls-core.exp:

The problem is that this gdb_test_multiple clause in gdb_core_cmd:
...
-re ": No such file or directory.*\r\n$gdb_prompt $" {
fail "$test (file not found)"
return -1
}
...
triggers on the message about raise.c, while it is intended to catch:
...
$ gdb
(gdb) core bla
/home/vries/bla: No such file or directory.
...
Fix this by making the regexp more precise:
...
- -re ": No such file or directory.*\r\n$gdb_prompt $" {
+ -re "$core: No such file or directory.*\r\n$gdb_prompt $" {
...
Tested on x86_64-linux.
Also tested the test-case with this patch in place to verify that the regexp
still triggers:
...

When on a MinGW host, standard_output_file uses a regular expression to
convert Unix-style paths of the form "/c/foo" to "c:/foo". This is
needed because the paths we pass to GDB (for example, with the "file"
command) need to be in the Windows form.
However, the regexp only works if your binutils-gdb repo is under a
`/[a-z]/...` path (the Unix paths mapping to Windows drives).
Presumably, that works if you clone the repo in Windows, then access it
through `/c/...`.
In my case, I've cloned the repository directly inside my MinGW shell,
so in /home/smarchi. The regexp therefore doesn't work for me. The
path doesn't get transformed, and the file command fails when running
any test:
(gdb) file /home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.arch/i386-bp_permanent/i386-bp_permanent
/home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.arch/i386-bp_permanent/i386-bp_permanent: No such file or directory.
A safer way to do this is to execute `pwd -W` while in the directory we
want the path for, this is what this patch does.
I have also considered using the using the cygpath utility to do the
conversion. It can be used to convert any MinGW path into its Windows
equivalent. Despite originally coming from Cygwin, the cygpath utility
is distributed by MinGW-w64 and can be used in that environment.
However, it's not distributed with the non-MinGW-w64 MinGW.
The `pwd -W` trick only works with directories that exist, which is the
case here, so it's sufficient.
With this, the file command in the test succeeds:
(gdb) file C:/msys64/home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.arch/i386-bp_permanent/i386-bp_permanent
Reading symbols from C:/msys64/home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.arch/i386-bp_permanent/i386-bp_permanent...

* lib/gdb.exp (standard_output_file): Use `pwd -W` to convert
from Unix to Windows path.

This commit adds the ability to set and toggle the DWARF line table
is-stmt flag.
A DWARF line table can now be created with the attribute
'default_is_stmt' like this:
lines {version 2 default_is_stmt 0} label {
...
}
If 'default_is_stmt' is not specified then the current default is 1,
which matches the existing behaviour.
Inside the DWARF line table program you can now make use of
{DW_LNS_negate_stmt} to toggle the is-stmt flag, for example this
meaningless program:
lines {version 2 default_is_stmt 0} label {
include_dir "some_directory"
file_name "some_filename" 1
program {
{DW_LNS_negate_stmt}
{DW_LNE_end_sequence}
}
}
This new functionality will be used in a later commit.
gdb/testsuite/ChangeLog:
* lib/dwarf.exp (Dwarf::lines) Add support for modifying the
is-stmt flag in the line table.

we run into:
...
gdb compile failed, gdb/contrib/gdb-add-index.sh: line 86: \

In lib/fortran.exp, in the helper function fortran_int4, kind
parameter is expected to be printed as (kind=4) for the LLVM
Fortran compiler, Flang along with gfortran. And in the helper
function fortran_int8 kind parameter is expected to be printed
as (kind=8). But for the Flang compiler default kind is not
printed and non default kind is printed differently than gfortran
as below.
integer(kind=4) => integer
integer(kind=8) => integer*8
real(kind=4) => real
real(kind=8) => double precision
complex(kind=4) => complex
logical(kind=4) => logical
character(kind=1) => character
This commit adds support for printing of kind parameter for the
Flang. There should be no change when testing with gfortran.
Note: The current patch overrides earlier patch with below details.
commit c3b149eb7697b376df1b3a47d0102afda389ee6d
Author Alok Kumar Sharma (alokkumar.sharma@amd.com)
Earlier patch was incomplete and based on assumption that flang
should be changed to dump a type with kind like the way gfortan does.
Later it was realized that the way flang dumps this info is not
incorrect but different. And changes in gdb test framework are
finalized.
gdb/testsuite/ChangeLog:
* lib/fortran.exp (fortran_int4): Handle flang kind printing.

(fortran_real4): Likewise.
(fortran_real8): Likewise.

This commit aims to give a cleaner mechanism by which the user can
prevent GDB from trying to load any previous command history.
Currently the user can change the path to the history file, either
using a command line flag, or by setting the GDBHISTFILE environment
variable, and if the path is set to a non-existent file, then
obviously GDB wont load any command history. However, this feels like
a bit of a bodge, I'd like to add an official mechanism by which we
can disable command history loading.
Why would we want to prevent command history loading? The specific
use case I have is GDB starting with a CWD that is a network mounted
directory, and there is no command history present. Still GDB will
access the network in order to check for the file. In my particular
use case I'm actually starting a large number of GDB instances in
parallel, all in the same network mounted directory, the large number
of network accesses looking for this file introduces a noticeable
delay at GDB startup.
The approach I'm proposing here is a slight adjustment to the current
rules for setting up the history filename. Currently, if a user does
this, they see an error:
(gdb) set history filename
Argument required (filename to set it to.).
However, if a user does this:
$ GDBHISTFILE= gdb --quiet
(gdb) set history save on
(gdb) q
warning: Could not rename -gdb18416~ to : No such file or directory
So, we already have a bug in this area. My plan is to allow the empty
filename to be accepted, and for this to mean, neither load, nor save
the command history.
This does mean that we now have two mechanisms to prevent saving the
command history:
(gdb) set history filename
or
(gdb) set history save off
But the only way to prevent loading the command history is to set the
filename to the empty string _before_ you get to a GDB prompt, either
using a command line option, or the environment variable.
I've updated some of the show commands, for example this session:
(gdb) set history filename
(gdb) show history filename
There is no filename currently set for recording the command history in.
(gdb) show history save
Saving of the history record on exit is off.
(gdb) set history save on
(gdb) show history save
Saving of the history is disabled due to the value of 'history filename'.
(gdb) set history filename /tmp/hist
(gdb) show history save
Saving of the history record on exit is on.
I've updated the manual, and added some tests.
gdb/ChangeLog:
* NEWS: Mention new behaviour of the history filename.
* top.c (write_history_p): Add comment.
(show_write_history_p): Add header comment, give a different
message when history writing is on, but the history filename is

optional.
gdb/doc/ChangeLog:
* gdb.texinfo (Command History): Extend description for
GDBHISTFILE and GDBHISTSIZE, add detail about the filename for
'set history filename' being optional. Describe the effect of an

Add gdb_test_multiple option -lbl, that adds a regexp after the user code that
reads one line, and discards it:
...
-re "\r\n\[^\r\n\]*(?=\r\n)" {

...
In order to be able to write:
...
gdb_test_multiple "command" "testname" -lbl {
...
}

rewrite the promp_regexp argument usage into the similar:
...
gdb_test_multiple "command" "testname" -prompt $prompt_regexp {

When running the gdb.tui test, spawn gets renamed to a local version from
lib/tuiterm.exp. The local version calls expect's spawn, and then makes the
local spawn_out(slave,name) variable accessible in the global variable
gdb_spawn_name.
However, the weird.exp test-case uses remote_exec build, which ends up using
local_exec, which given that there's input/output redirection uses open:
...
set result [catch {open "| ${commandline} $inp |& tee $outpf" RDONLY} id]
...
followed by spawn using the -leaveopen option:
...
set result [catch "spawn -ignore SIGHUP -leaveopen $id" result2]
...
which apparently has the effect that spawn_out(slave,name) is not set.
Fix this in the lib/tuiterm.exp local spawn proc by detecting the case that
spawn_out(slave,name) is not set, and handling it accordingly.
Tested gdb.stabs/weird.exp and gdb.tui/*.exp on x86_64-linux.

For running the DejaGnu tests, some esoteric configurations
may require a testglue. This, for instance, is true about
testing ARC targets which uses its own DejaGnu board and
a simulator which does not support returning the program's exit
code. Therefore, for those tests that use "gdb_compile", a
"gdb_tg.o" file is compiled and linked into the final
executable.
There are tests that invoke "gdb_compile" from different
directories. Let's take a look at an example test:
gdb.base/fullname.exp. The purpose of this test is to build
the executable from different directories (absolute vs. relative
vs. other) and then check if gdb can handle setting breakpoints
accordingly.
When "gdb_compile" generates the "gdb_tg.o", it does not
do it again for the same test. Although this might seem
efficient, it can lead to problems when changing directories
before the next compile:
gdb compile failed, arc-elf32-gcc: error: gdb_tg.o:
No such file or directory
This patch checks if the wrapper file ("gdb_tg.o") is still in
reach and if it is not, it will stimulate the regeneration of
the wrapper.
It is worth mentioning that GCC's DejaGnu tests handle these
scenarios as well and they seem to be more efficient in doing so
by saving the library paths and manipulating them if necessary
[1]. However, for GDB tests, that require less compilations,
I think the proposed solution should be fine compared to a more
full fledged solution from GCC. The glue file in our case is
only 2 KiB.
Last but not least, I ran the x86_64 tests on an x86_64 host and
found no regression.

Before commit d4295de4f3 "[gdb/testsuite] Handle missing gnatmake in
gnat_runtime_has_debug_info", calling the gdb_caching_proc
gnat_runtime_has_debug_info could generate a pass because of using
gdb_compile_ada.
This has been fixed in that commit by using a factored out variant
gdb_compile_ada_1, which does not call pass.
Additionally, fix cases like this in more generic way: by ignoring pass calls
during execution of a gdb_caching_proc.

Fix this by using quiet as additional option to gdb_compile in
dtrace_build_usdt_test_program. Note that the error message still occurs in

After de-installing gnatmake, I get on stdout/stderr:

In gdb.sum, we see these FAILs (each paired with an UNSUPPORTED as well)
followed by:
...
PASS: gdb-caching-proc.exp: gnat_runtime_has_debug_info consistency
...
Likewise, after re-installing gnatmake, I get a PASS for each of the
UNSUPPORTEDs, and the FAILs disappear.
The FAIL comes from gnat_runtime_has_debug_info, the PASS/UNSUPPORTED comes
from gdb_compile_ada.
Fix this by removing the corresponding fail call in
gnat_runtime_has_debug_info, as well as using a new variant gdb_compile_ada_1
that doesn't call pass/unsupported.

The test-case gdb.server/server-kill-python.exp runs fine by itself:
...
Running src/gdb/testsuite/gdb.server/server-kill-python.exp ...

...
But if we run f.i. gdb.server/file-transfer.exp before it, we get instead:
...
Running src/gdb/testsuite/gdb.server/server-kill-python.exp ...
ERROR: GDB process no longer exists
=== gdb Summary ===

Process build/gdb/testsuite/outputs/gdb.server/file-transfer/file-transfer
\ created; pid = 9464^M
Listening on port 2347^M
...
The spawn of the gdbserver for the server-kill-python test-case gets as
executable argument the file-transfer binary.
This is caused by proc gdbserver_spawn attempting to load the exec file in
$file_last_loaded. This is something that is meant to load the same exec in
the gdbserver that was earlier loaded into gdb.
In this test-case however, nothing has been loaded into gdb by the test-case,
and consequently we load the file that was loaded into gdb in the previous
test-case.
Fix this by unsetting $file_last_loaded in gdb_init.

In lib/fortran.exp, in the helper function fortran_int4, there is
currently no support for the LLVM Fortran compiler, Flang. As a
result we return the default pattern 'unknown' to match against all
4-byte integer types, which causes many tests to fail.
The same is true for all of the other helper functions related to
finding a suitable type pattern.
This commit adds support for Flang. There should be no change when
testing with gfortran.

The inferior_exited_re regexp uses capturing parentheses by default:
...
set inferior_exited_re "(\\\[Inferior \[0-9\]+ \\(.*\\) exited)"
...
The parentheses are there to be able to use the expression as an atom, f.i.,
to have '+' apply to the whole regexp in "${inferior_exited_re}+".
But the capturing is not necessary, and it can be confusing because it's not
obvious in a regexp using "$inferior_exited_re (bla|bli)" that the first
captured expression is in $inferior_exited_re.
Replace by non-capturing parentheses. If we still want to capture the
expression, we can simply (and more clearly) use "($inferior_exited_re)".

Fixes a bug in the DWARF assembler that prevents multiple line tables
from being created in a test. We currently don't initialise a couple
of flags, as a result we will only ever generate one end of file list,
and one end of header, in the first line table. Any additional line
tables will be missing these parts, and will therefore be corrupt.
This fix will be required for a later commit. There should be no

In tui-wingeneral.c:box_win () a comment suggest we should display

titles will appear as:

This adds a testcase exercising multi-target features. It spawns 6
inferiors, like this:
inferior 1 -> native
inferior 2 -> extended-remote 1
inferior 3 -> core
inferior 4 -> native
inferior 5 -> extended-remote 2
inferior 6 -> core
and then tests various details, including:
- running to breakpoints
- interrupting with Ctrl-C and "interrupt -a"
- "next" bouncing between two breakpoints in two threads running in
different targets.
- since we have cores and live inferiors mixed in the same session,
this makes sure that gdb doesn't try to remove a core dump's
threads.
- all-stop and non-stop modes.
This testcase caught a _lot_ of bugs in development.

Hannes Domani pointed out that my previous patch to fix the "list"
command in the TUI instead broke vertical scrolling. While looking at
this, I found that do_scroll_vertical calls print_source_lines, which
seems like a very roundabout way to change the source window. This
patch removes this oddity and fixes the bug at the same time.
I've added a new test case. This is somewhat tricky, because the
obvious approach of sending a dummy command after the scroll did not
work -- due to how the TUI works, sennding a command causes the scroll
to take effect.

The Term::dump_screen routine currently dumps the screen using calls
to 'verbose', this means it will only dump the screen when the
testsuite is running in verbose mode.
However, the Term::dump_screen is most often called when a test fails,
in this case I think it is useful to have the screen dumped even when
we're not in verbose mode.
This commit changes the calls to 'verbose' to be 'verbose -log' so we
always get the screen dump.

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.

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

The gdb.fortran/info-modules.exp and gdb.fortran/info-types.exp tests
are failing on versions of gfortran after 7.3 due to the inclusion of
extra "system" modules and type that were not being matched by the
current test patterns.
Rather than building increasingly complex patterns that would always
be at risk of breaking with future versions of GCC I have instead
added a new library that parses the output of the following commands:
info types
info variables
info functions
info modules
info module functions
info module variables
into a data structure, the test can than run checks against the
contents of this data structure.
The benefit is that we can simply ignore extra results that we don't
care about.
There is a small risk that a bug in GDB might allow us to start
reporting incorrect results in such a way that the new library will
not spot the error. However, I have tried to mitigate this risk by
adding extra procedures into the test library (see check_no_entry) and
we can add more in future if we wanted to be even more defensive.
I tested this test file with gFortran 7.3.1, 8.3.0, and 9.2.0, I now
see 100% pass in all cases.

When compiling Fortran tests (e.g. gdb.fortran/info-modules.exp), the
Fotran compile produces .mod files. These files contain details of
compiled modules that are then consumed by the compiler when compiling
other files that USE a module.
Currently the compiler writes the .mod files into its current
directory, so for us this turns out to be 'build/gdb/testsuite/'.
This means that .mod files can be shared between tests, which seems
against the spirit of the GDB testsuite; source files should be
compiled fresh for each test.
This commit adds the -J option to the compiler flags whenever we
compile a Fortran file, this option tells the compiler where to write,
and look for, .mod files.
After this commit there was one Fortran test that needed fixing, with
that fix in place all of the Fortran tests pass again, but now the
.mod files are now produced in the per-test output directories.

As Sergio pointed out, the TUI resizing tests are flaky. Debugging
this showed three main problems.
1. expect's "stty" command processes its arguments one-by-one. So,
rather than requesting a single resize, it sends two separate resize
requests (one for rows and one for columns). This means gdb sees two
SIGWINCH signals and resizes the terminal twice.
I consider this a bug in expect, but I couldn't readily see how to
report a bug; and anyway the fix wouldn't propagate very quickly.
This patch works around this problem by explicitly doing two separate
resizes (so it will be robust if expect ever does change); and then by
waiting for each resize to complete before continuing.
2. gdb uses curses to drive the console rendering. Currently the test
suite looks for terminal text insertion sequences to decide when a
command has completed. However, it turns out that, sometimes, curses
can output things in non-obvious ways. I didn't debug into curses but
I guess this can happen due to output optimizations. No matter the
reason, sometimes the current approach of only tracking text
insertions is not enough to detect that gdb has finished rendering.
This patch fixes this problem by arranging to detect the termination
output after any curses command, not just insertion.
3. Detecting when a resize has completed is tricky. In fact, I could
not find a way to reliably do this.
This patch fixes this problem by adding a special maint
"tui-resize-message" setting to gdb. When this is enabled, gdb will
print a message after each SIGWINCH has been fully processed. The
test suite enables this mode and then waits for the message in order
to know when control can be returned to the calling test.
This patch also adds a timeout, to avoid the situation where the
terminal code fails to notice a change for some reason. This lets the
test at least try to continue.

There's a pattern:
...
gdb_test <command> <pattern> <command>
...
that can be written shorter as:
...
gdb_test <command> <pattern>
...
Detect this pattern in proc gdb_test:
...
global gdb_prompt
upvar timeout timeout
if [llength $args]>2 then {
set message [lindex $args 2]
+ if { $message == [lindex $args 0] && [llength $args] == 3 } {
+ error "HERE"
+ }
} else {
set message [lindex $args 0]
}
...
and fix all occurrences in some gdb testsuite subdirs.
Tested on x86_64-linux.

Proc gdb_test_multiple builds up and executes a gdb_expect expression with
pattern/action clauses. The clauses are either implicit (added by
gdb_test_multiple) or explicit (passed via the gdb_test_multiple parameter
user_code).
However, there are a few implicit clauses which are inserted before the
explicit ones, making sure those take precedence.
Add an -early pattern flag for a gdb_test_multiple user_code clause to specify
that the clause needs to be inserted before any implicit clause.
Using this pattern flag, we can f.i. setup a kfail for an assertion failure
<assert> during gdb_continue_to_breakpoint by the rewrite:
...
gdb_continue_to_breakpoint <msg> <pattern>
...
into:
...
set breakpoint_pattern "(?:Breakpoint|Temporary breakpoint) .* (at|in)"
gdb_test_multiple "continue" "continue to breakpoint: <msg>" {
-early -re "internal-error: <assert>" {
setup_kfail gdb/nnnnn "*-*-*"
exp_continue
}
-re "$breakpoint_pattern <pattern>\r\n$gdb_prompt $" {
pass $gdb_test_name
}
}
Tested on x86_64-linux.
