When running the gdb.dlang test-cases, and forcing gdb_find_gdc to be used
rather than dejagnu's copy (mimicing what happens with an older dejagnu
without find_gdc), I run into these debug prints:
...

This commit changes mi_make_breakpoint_pending to accept the 'script'
and 'times' arguments.
I've then added a new test that makes use of 'scripts' in
gdb.mi/mi-pending.exp and gdb.mi/mi-dprintf-pending.exp.
There is already a test in gdb.mi/mi-pending.exp that uses the 'times'
argument -- previously this argument was being ignored, but is now
used.

[gdb/testsuite] Fix unbalanced quotes in mi_expect_stop argument
Introduced the use of {"} in mi-support.exp. There is absolutely
nothing wrong with this in any way. However, this is causing my
editor to get the syntax highlighting of this file wrong after this
point.
Maybe the real answer is to use a better editor, or fix my current
editor.... but I'm hoping I can instead take the lazy approach of just
changing {"} to "\"", which is handled fine, and means exactly the
same as far as I understand it.
There should be no change in what is tested after this commit.

Proc gdb_test_multiple has special handling for multi-line commands, which
splits it up into subcommands, and for each subcommand issues it and then
waits for the resulting prompt (the secondary prompt ">" for all but the last
subcommand).
However, that doesn't work as expected in this case because the initial
gdb_test_multiple "define remove" fails to match all resulting output, and
consequently the secondary prompt resulting from "define remove" is counted as

Fix this by matching the entire output of "define remove", including the
secondary prompt.

This adds a 'rust_at_least' helper proc, for checking the version of
the Rust compiler in use. It then changes various tests to use this
with 'require'.
PR mi/11335 points out that an MI varobj will not display the result
of a pretty-printer's "to_string" method. Instead, it always shows
"{...}".
This does not seem very useful, and there have been multiple
complaints about it over the years. This patch changes varobj to emit
this string when possible, and updates the test suite.

When an allow_* proc returns false, it can be a bit difficult what check
failed exactly, if the procedure does multiple checks. To make
investigation easier, I propose to allow the "require" callbacks to be
able to return a list of two elements: the zero/non-zero value, and a
reason string.

where I hit actually hit this inconvenience). On my computer (where GDB
is built with amd-dbgapi support but where I don't have a suitable GPU
target), I get:

In do_self_tests we try to find out the location of the gdb to debug, which
will then be copied and renamed to xgdb.
In principle, the host board specifies the location of GDB, on host.
With remote host, we could upload that gdb from host to build/target, but we
would miss the data directory (which is listed as the reason to skip
do_self_tests for remote target).
We could fix that by instead taking the gdb from build instead, but that
wouldn't work with installed testing.
It seems easier to just skip this on remote host.
It could be made to work for the "[is_remote host] && [is_remote target]

that doesn't seem worth the effort.

In proc mi_expect_stop there's a proc argument reason that's handled like so:
...
set r "reason=\"$reason\","
...
That's fine for say:
...
set reason "foo"
...
for which this evaluates to:
...
set r "reason=\"foo\","
...
But there are more complex uses, for instance:
...
set reason "breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal"
...
which evaluates to:
...
set r "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\""
...
Note how in this reason argument, the first two '\"' seems to form a pair
surrounding ',disp=', which is not the case, which is confusing.
Fix this by only adding the quotes in mi_expect_stop if the string doesn't
already contain quotes, such that we have the more readable:

set reason "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\""

allow_opencl_test, which takes care of:
- downloading to a location which is safe for parallel testing, by

"remote_file target delete ${clprogram}" lines in allow_opencl_test.

Commit 1acc9dca42 ("Change linetables to be objfile-independent")
changed "maintenance info line-table" to print unrelocated addresses
instead of relocated. This breaks a few tests on systems where that
matters. The ones I see are:
Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/consecutive.exp ...

FAIL: gdb.base/async.exp: nexti&

These tests run "maintenance info line-table" to record the address of
some lines, and then use these addresses in expected patterns. It
therefore expects these addresses to match the runtime addresses,
therefore the relocated addresses.
Add back the relocated addresses, next to the unrelocated addresses,
like so:
INDEX LINE REL-ADDRESS UNREL-ADDRESS IS-STMT PROLOGUE-END
0 6 0x0000555555555119 0x0000000000001119 Y

3 END 0x0000555555555125 0x0000000000001125 Y
The unrelocated addresses can always be useful trying to map this
information with a DWARF info dump.
Adjust the is_stmt_addresses proc in the testsuite to match the new
output.

Dejagnu's remotedir implementation has support in remote_exec and
remote_download, but not remote_upload.
Consider the following scenario:
- downloading an executable to target,
- running it,
- uploading a file produced by the executable
while assuming remote target user remote-target with homedir
/home/remote-target and remotedir set to /home/remote-target/tmp.
Concretely, it looks like this:
...
# binfile == "$outputs/gdb.abc/a.out"
set target_binfile [remote_download target $binfile]
# target_binfile == "/home/remote-target/tmp/a.out"
remote_exec target $target_binfile
# Running $target_binfile produced /home/remote-target/tmp/result.txt.
set result [remote_upload target /home/remote-target/tmp/result.txt \
$outputs/gdb.abc/result.txt]
# result == $outputs/gdb.abc/result.txt.
...
Add a remote_upload implementation that also handles remotedir in lib/gdb.exp,
overriding dejagnu's remote_upload, such that we can simplify the
remote_upload call to:
...
set result [remote_upload target result.txt $outputs/gdb.abc/result.txt]

...
- spawn $RSH -t -l $username $remote $cmd

maintenance-unfriendly.

The failure is caused by the 'evaluated-by="host"' string, which only

I could fix this by just updating the pattern in
gdb.mi/mi-pending.exp, but I have instead updated mi-pending.exp to
make more use of the support procs in mi-support.exp. This did
require making a couple of adjustments to mi-support.exp, but I think
the result is that mi-pending.exp is now easier to read, and I see no
failures with native-extended-remote anymore.
One of the test names has changed after this work, I think the old

breakpoint was not pending, I suspect a copy & paste error.
But there's no changes to what is actually being tested after this

I noticed that several tests included copy & pasted code to run the

result.
In this commit I factor this code out into a helper proc in

Introduce foreach_mi_ui_mode, a helper proc which can be used when
tests are going to be repeated once with the MI in the main UI, and
once with the MI on a separate UI.
The proc is used like this:
foreach_mi_ui_mode VAR {
# BODY
}
The BODY will be run twice, once with VAR set to 'main' and once with
VAR set to 'separate', inside BODY we can then change the behaviour
based on the current UI mode.
The point of this proc is that we sometimes shouldn't run the separate
UI tests (when gdb_debug_enabled is true), and this proc hides all
this logic. If the separate UI mode should not be used then BODY will
be run just once with VAR set to 'main'.
I've updated two tests that can make use of this helper proc. I'm
going to add another similar test in a later commit.

The mi_clean_restart proc calls the mi_gdb_start proc passing no
arguments.
In this commit I add an extra (optional) argument to the
mi_clean_restart proc, and pass this through to mi_gdb_start.
The benefit of this is that we can now use mi_clean_restart when we
also want to pass the 'separate-mi-tty' or 'separate-inferior-tty'
flags to mi_gdb_start, and avoids having to otherwise duplicate the
contents of mi_clean_restart in different tests.
I've updated the obvious places where this new functionality can be
used, and I'm seeing no test regressions.

When creating a thread-specific breakpoint with a single location, the
'thread' field would be repeated in the MI output. This can be seen
in two existing tests gdb.mi/mi-nsmoribund.exp and
gdb.mi/mi-pending.exp, e.g.:
(gdb)
-break-insert -p 1 bar
^done,bkpt={number="1",type="breakpoint",disp="keep",
enabled="y",
addr="0x000000000040110a",func="bar",
file="/tmp/mi-thread-specific-bp.c",
fullname="/tmp/mi-thread-specific-bp.c",
line="32",thread-groups=["i1"],
thread="1",thread="1", <================ DUPLICATION!
times="0",original-location="bar"}
I know we need to be careful when adjusting MI output, but I'm hopeful
in this case, as the field is duplicated, and the field contents are
always identical, that we might get away with removing one of the
duplicates.
The change in GDB is a fairly trivial condition change.
We did have a couple of tests that contained the duplicate fields in
their expected output, but given there was no comment pointing out
this oddity either in the GDB code, or in the test, I suspect this was
more a case of copying whatever output GDB produced and using that as
the expected results. I've updated these tests to remove the
duplication.
I've update lib/mi-support.exp to provide support for building
breakpoint patterns that contain the thread field, and I've made use
of this in a new test I've added that is just about creating
thread-specific breakpoints and checking the results. The two tests I
mentioned above as being updated could also use the new
lib/mi-support.exp functionality, but I'm going to do that in a later
patch, this way it is clear what changes I'm actually proposing to
make to the expected output.
As I said, I hope that frontends will be able to handle this change,
but I still think its worth adding a NEWS entry, that way, if someone
runs into problems, there's a chance they can figure out what's going
on.
This should not impact CLI output at all.

When looking at some failures of gdb.linespec/cp-completion-aliases.exp,
I noticed that when a completion test will fail, it always fails with a
timeout. This is because most completion tests use gdb_test_multiple
and only add a check for the correct output. This commit adds new
options for both, tab and command completion.
For command completion, the new option will check if the prompt was
printed, and fail in this case. This is enough to know that the test has
failed because the check comes after the PASS path. For tab completion,
we have to check if GDB outputted more than just the input line, because
sometimes GDB would have printed a partial line before finishing with
the correct completion.
