This testcase was originally for PR gdb/15415, a problem with the
"run" command expanding symlinks in the name of the program being run.
It does not correctly distinguish between files on build, host, and
target, and it is not clear if it would be testing anything useful in
configurations where "run" is not being used.

The gdb.fortran/info-types.exp test-case passes with gcc 7 (though not on
openSUSE, due to the extra debug info) and fails with gcc 4.8 and gcc 8.
Fix the gdb_test regexp to fix all those cases.

On openSUSE Leap 15.1, I get:
...
FAIL: gdb.base/info-var.exp: info variables
FAIL: gdb.base/info-var.exp: info variables -n
...
because the info variables command prints info also for init.c:
...
File init.c:^M
24: const int _IO_stdin_used;^M
...
while the regexps in the test-case only expect info for info-var-f1.c and
info-var-f2.c.
Fix this by extending the regexps.
Tested on x86_64-linux, both openSUSE Leap 15.1 and Fedora 30.

Currently the 'info types' command will return symbols that correspond
to Fortran modules. This is because the symbols are created with
domain MODULE_DOMAIN and address_class LOC_TYPEDEF. The address_class
LOC_TYPEDEF is the same address_class used for type symbols which is
why the modules show up when listing types.
This commit explicitly prevents symbols in the MODULE_DOMAIN from
appearing when we search for symbols in the TYPES_DOMAIN, this
prevents the Fortran module symbols from appearing in the output of
'info types'.
gdb/ChangeLog:
* symtab.c (search_symbols): Don't include MODULE_DOMAIN symbols
when searching for types.
gdb/testsuite/ChangeLog:
* gdb.fortran/info-types.exp: Add module.
* gdb.fortran/info-types.f90: Update expected results.

Implement an la_print_typedef method for Fortran, this allows 'info
types' to work for Fortran. The implementation is just copied from
ada_print_typedef (with the appropriate changes).
To support the testing of this patch I added a new proc,
fortran_character1, to lib/fortran.exp which returns a regexp to match
a 1-byte character type. The regexp returned is correct for current
versions of gFortran. All of the other regexp are guesses based on
all of the other support procs in lib/fortran.exp, I haven't tested
them myself.

The 'info variables', its alias 'whereis', and 'info functions' all
include non-debug symbols in the output by default. The list of
non-debug symbols can sometimes be quite long, resulting in the

When using catch catch/rethrow/catch, a libstdcxx with SDT probes is required
for both the regexp argument, and the convenience variable $_exception (
https://sourceware.org/gdb/current/onlinedocs/gdb/Set-Catchpoints.html ).
Currently, when using these features with a libstdcxx without SDT probes, we
get the cryptic error message:
...
not stopped at a C++ exception catchpoint
...
Improve this by instead emitting the more helpful:
...
did not find exception probe (does libstdcxx have SDT probes?)
...

"SyntaxWarning: invalid escape sequence")
The way unrecognized escape sequences are handled has changed in
Python 3.8: users now see a SyntaxWarning message, which will
eventually become a SyntaxError in future versions of Python:
(gdb) source /blabla/gdb.python/py-xmethods/py-xmethods.py
/blabla/gdb.python/py-xmethods/py-xmethods.py:204: SyntaxWarning: invalid escape seque
nce \+
'operator\+',
/blabla/gdb.python/py-xmethods/py-xmethods.py:211: SyntaxWarning: invalid escape seque
nce \+
'operator\+\+',
One of our testcases, gdb.python/py-xmethods.exp, contains strings in
the form of "operator\+". This is not recognized by Python, but is
still needed by the testsuite to work properly. The solution is
simple: we just have to make sure these strings are marked as
raw (i.e, r""). This is what this patch does. I took the opportunity
to also convert other strings to raw, which, in two cases, allowed the
removal of an extra backslash.
I tested this using Python 3.7 and Python 3.8, and everything works
fine.
I think I could push this as obvious, but decided to send it to
gdb-patches just in case.

When running a pascal test with the stabs target board:
...
$ test=gdb.pascal/case-insensitive-symbols.exp
$ cd build/gdb/testsuite
$ make check RUNTESTFLAGS="$test --target_board=stabs"
...
we get:
...
nr of untested testcases 1
nr of unsupported tests 1
...
due to:
...
Error: Illegal parameter: -gstabs+^M
Error: /usr/bin/ppcx64 returned an error exitcode^M
...
OTOH, when running the same pascal test without the stabs target board:
...
$ make check RUNTESTFLAGS="$test"
...
we get:
...
nr of expected passes 20
...
But when subsequently again running with the stabs target board:
...
$ make check RUNTESTFLAGS="$test --target_board=stabs"
...
we now get:
...
nr of expected passes 20
...
The problem is that gdb_compile_pascal determines success based on existence
of the exec after compilation:
...
if ![file exists $destfile] {
unsupported "Pascal compilation failed: $result"
return "Pascal compilation failed."
}
...
without removing the exec before compilation, which allows a stale exec to
make it seem as if compilation has succeeded.

The TUI execution info window is unusual in that it is always linked
to a source or disassembly window. Even updates of its content are
handled by the source window, so it really has no life of its own.
This patch removes this window entirely and puts its functionality
directly into the source window. This simplifies the code somewhat.
This is a user-visible change, because now the box around the source
(or disassembly) window encloses the execution info as well. I
consider this an improvement as well, though.
Note that this patch caused ncurses to start emitting the "CSI Z"
sequence, so I've added this to the test suite terminal
implementation.

c8ad9b9a31aa3e6039567fc1f152dd454c946d5f. Previously the regexp for

The TUI currently has two different ways to resize a window: the
resize method, and the methods make_invisible_and_set_new_height and
make_visible_with_new_height.
There's no deep reason to have two different ways to resize a window,
so this patch unifies them, leaving just the "resize" method.
This also changes the locator to be handled more like an ordinary
window and less like an adjunct of the associated source window.

After the sync there is one testsuite regression, the test
"signal SIGINT" in gdb.gdb/selftest.exp which now FAILs. Previously,
the readline 6.2 SIGINT handler would temporarily reinstall the
underlying application's SIGINT handler and immediately re-raise SIGINT
so that the orginal handler gets invoked. But now (since readline 6.3)
its SIGINT handler does not re-raise SIGINT or directly invoke the
original handler; it now sets a flag marking that SIGINT was raised, and
waits until readline explicitly has control to call the application's
SIGINT handler. Anyway, because SIGINT is no longer re-raised from
within readline's SIGINT handler, doing "signal SIGINT" with a stopped
inferior gdb process will no longer resume and then immediately stop the
process (since there is no 2nd SIGINT to immediately catch). Instead,
the inferior gdb process will now just print "Quit" and continue to run.
So with this commit, this particular test case is adjusted to reflect
this change in behavior (we now have to send a 2nd SIGINT manually to
stop it).

^[[0;10m<SNIP>+++ _csi_m <<<0;10>>>
...
The problem is that this regexp in _accept:
...
-re "^\x1b\\\[(\[0-9;\]*)(\[0-9a-zA-Z@\])" {
...
while matching the longer sequence '^[' '[' '0' ';' '1' '0' 'm', also matches
the shorter sequence '^[' '[' '0'.
The regexp attempts to match a CSI (Control Sequence Introducer) sequence, and
the final byte of such a sequence cannot be a digit.
Fix the regexp accordingly:
...
- -re "^\x1b\\\[(\[0-9;\]*)(\[0-9a-zA-Z@\])" {
+ -re "^\x1b\\\[(\[0-9;\]*)(\[a-zA-Z@\])" {
...

With this patch, the help docs now respect 2 invariants:
* The first line of a command help is terminated by a '.' character.
* The last character of a command help is not a newline character.
Note that the changes for the last invariant were done by Tom, as part of :
[PATCH] Remove trailing newlines from help text
https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.
Some help docs had to be rephrased/restructured to respect the above
invariants.
Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.
This was giving inconsistent results :
* The first line of command helps was sometimes '.' terminated,
sometimes not.
* The first line of command helps was not always designed to be
readable/understandable/unambiguous when stopping at the first
'.' or ',' character.
This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.
Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.
This patch changes the help documentations to ensure the 2 invariants
given above.
It implied to slightly rephrase or restructure some help docs.
Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.
This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

This adds more styling to the disassemble command. In particular,
addresses and function names in the disassembly are now styled.
This required fixing a small latent bug in set_output_style. This
function always passed NULL to emit_style_escape; but when writing to
a file other than gdb_stdout, it should emit the style escape
directly. (FWIW this is another argument for better integrating the
pager with ui_file and getting rid of this entire layer.)

Running
make check-read1 TESTS="gdb.mi/list-thread-groups-available.exp"
on my machine results in timeout failures. Running it while having
`tail -F testsuite/gdb.log` on the side shows that the test is never
really blocked, it is just slow at consuming the large output generated
by `-list-thread-groups --available` (which lists all the processes on
the system).
If I increase the timeout to a large value, the test passes in ~30
seconds (compared to under 1 second normally).
Increase the timeout for the particular mi_gdb_test that is long to
execute under read1. The new timeout value is a bit arbitrary. The
default timeout is 10 seconds, so I set the new timeout to be
"old-timeout * 10", so 100 seconds in the typical case.

When running gdb.base/break-idempotent.exp with

The test-case is compiled once with nopie and once with pie, but in both cases

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