The 'kind' keyword has two uses in Fortran, it is the name of a
builtin intrinsic function, and it is also a keyword used to create a
type of a specific kind.
This commit adds support for using kind as an intrinsic function, and
also adds some initial support for using kind to create types of a
specific kind.
This commit only allows the creation of the type 'character(kind=1)',
however, it will be easy enough to extend this in future to support
more type kinds.
The kind of any expression can be queried using the kind intrinsic
function. At the moment the kind returned corresponds to the size of
the type, this matches how gfortran handles kinds. However, the
correspondence between kind and type size depends on the compiler
and/or the specific target, so this might not be correct for
everyone. If we want to support different compilers/targets in future
the code to compute the kind from a type will need to be updated.

This is an initial restructure, it adds a new function in which
Fortran specific expressions can be evaluated. No Fortran specific
expressions are added with this commit though, so for now, the new
function just forwards all expressions to the default expression
handler, as such, there should be no user visible changes after this
commit. However, the new function will be useful in later commits.

Use strncasecmp to compare Fortran dot operations (like .AND.) and for
the keywords list. This allows for some duplication to be removed
from the token arrays. I've also performed whitespace cleanup around
the code I've changed.
I have added some tests to ensure that upper and lowercase dot
operations are correctly tested. The keywords list remains always
lowercase for now.

this list might be case sensitive.
gdb/testsuite/ChangeLog:
* gdb.fortran/dot-ops.exp: New file.
This patch cleans up the code used for parsing the Fortran logical

I've also switched to use ARRAY_SIZE for the array iteration, and I've
cleaned up whitespace in the vicinity of the code I've changed.
Finally, I've added a test to ensure that both the upper and lower
case versions of the logical constants are understood by GDB,
something that was missing previously.

get_compiler_info switches to a new log file before checking the compiler
to ensure the checks are not logged. Afterwards it restores back to using
the original log file. However, the logfile uses a relative path name -
if the current test has changed the current directory then all further
output for the test will be lost. This can confuse the code that collates
the main gdb.log file at the end of a FORCE_PARALLEL run.
fullpath-expand.exp calls gdb_compile after changing the current directory.
The "Ensure stack protection is off for GCC" patch added a call to
get_compiler_info from inside of gdb_compile, causing log file collection
to break for FORCE_PARALLEL runs.
The ideal solution would be to ensure the log file is always created using
an absolute path name. However, this is set at multiple points in
Makefile.in and in some instances just relies on dejagnu common code to set
the log file directory to "."
The simpler and safer solution is to override the builtin cd function. The
new function checks the current log file and if the path is relative, then
it resets the logging using an absolute path. Finally it calls the builtin
cd. This ensures get_compiler_info (and any other code) can correctly
backup and restore the current log file.

Prior to this patch, calling functions on the inferior with arguments and
then using these arguments within a function resulted in an invalid
memory access. This is because Fortran arguments are typically passed as
pointers to values.
It is possible to call Fortran functions, but memory must be allocated in
the inferior, so a pointer can be passed to the function, and the
language must be set to C to enable C-style casting. This is cumbersome
and not a pleasant debug experience.
This patch implements the GNU Fortran argument passing conventions with
caveats. Firstly, it does not handle the VALUE attribute as there is
insufficient DWARF information to determine when this is the case.
Secondly, functions with optional parameters can only be called with all
parameters present. Both these cases are marked as KFAILS in the test.
Since the GNU Fortran argument passing convention has been implemented,
there is no guarantee that this patch will work correctly, in all cases,
with other compilers.
Despite these limitations, this patch improves the ease with which
functions can be called in many cases, without taking away the existing
approach of calling with the language set to C.

While debugging gdb, I printed the target stack and got:
(top-gdb) p g_target_stack
$10 = {
m_top = thread_stratum,
m_stack = {0x142b0b0, 0x13da600 <exec_ops>, 0x1c70690, 0x13d63b0 <ravenscar_ops>, 0x0, 0x0, 0x0}
}
(This is clearly from before the change to make ravenscar
multi-target-capable.)
Here, 0x142b0b0 is the singleton dummy target. It seems to me that
since this is always a singleton, it would be a bit nicer if it were a
global, so that it would be noted in the above.
This patch implements this idea, and now I get:
(top-gdb) p g_target_stack
$2 = {
m_top = dummy_stratum,
m_stack = {0x1f1b040 <the_dummy_target>, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}
}

to me.

The synopsis of the two-parameters form of the gdb.Value constructor is

Value.__init__ (val, [, type ])

First, there is an extra comma, which I think we can remove in any

Then, since the type parameter is not optional, I would not put in
between square brackets. Those usually indicate that something is
optional.

A customer noticed some mildly odd MI output, where CLI output was
split into multiple MI strings at unusual boundaries, like this:
~"$1 = (b => true"
~", p => 0x407260"
This is technically correct according to the MI spec, but still
unusual, in that there's no particular reason for the string to be
split where it is.
I tracked this down to a call to gdb_flush in generic_val_print.
Then, I went through all calls to gdb_flush and removed the ones I
thought were superfluous. In particular:
* Any call in the value-printing code;
* Likewise the type-printing code (just a single call); and
* Any call that immediately followed a printf that obviously
ended with a newline, my belief being that gdb's standard output
streams are line buffered (by inheriting the behavior from stdio)
Regression tested on x86-64 Fedora 29.
I didn't add a new test case. I tend to think we don't necessarily
want to specify this behavior in the tests. Let me know what you

On commit 8ecfd7bd4a ("Add parameter to
allow enabling/disabling selftests via configure") it seems that I
forgot to use the proper '$enable_unittest' variable when checking to
see whether to add selftest-related objects to 'srv_regobj'. This
causes a build failure on Aarch64 when 'development=false' (which is
the case for the 8.3 branch) and 'enable_unittest=true'.
This patch fixes the problem by using '$enable_unittest' instead of
'$development' when performing the check. As a reminder, it's
important to notice that '$enable_unittest's default value (i.e., when
the option '--enable-unit-tests' is not passed to configure) is the
same as '$development', so this patch doesn't affect the current
build.
I'd like to install this patch both on master and on the 8.3 branch.

* configure.srv: Use '$enable_unittest' instead of '$development'
when checking whether to fill 'srv_regobj' on 'aarch64*-*-linux*'
case.
This patch fixes test case failures observed when running
short-circuit-argument-list.exp with gdb server boards. Thanks to Sergio
Durigan Junior for pointing this out.
Assertions failed with the native{,-extended}-gdbserver boards as the
standard output from the test program appears in a different location
than observed on non-gdbserver boards. This standard output was used to
determine whether a function, which had been logically short-circuited,
was called or not. Since the location of the standard out cannot be
relied upon to verify this, a new mechanism was needed.
The test program now records function calls in variables named the same
as the function with a "_called" suffix. These variables can then be
queried from the test case to verify the occurrence of a call.
A method to reset the call counts has been included in the test case, so
that any future assertions added to this test can ensure a fresh set of
initial values before proceeding. Not resetting values between groups of
assertions creates a dependency between them, which increases the
likelihood that a single failure causes subsequent assertions to fail.

According to the specification for the CIE entries, when the CIE version is 1 then
the return address register field is always 1 byte. Readelf does this correctly in
read_cie in dwarf.c but ld does this incorrectly and always tries to read a
skip_leb128. If the value here has the top bit set then ld will incorrectly read
at least another byte, causing either an assert failure or an incorrect address to
be used in eh_frame.
I'm not sure how to generate a generic test for this as I'd need to write assembly,
and it's a bit hard to trigger. Essentially the relocated value needs to start with

When launching gdbserver, the testsuite checks for binding failure but
does not check for failure to listen to socket error (which can happen
due to another gdbserver binding to the socket at the same time).
When this error occurs, the test will ignore the error and connect GDB
to the failed port. This may succeed and GDB will now be connected to
the gdbserver from another test. This eventually causes both tests to
fail.
When running the tests suite with native-gdbserver across many cores,
this issue may happen once or twice, each causing random failures for
two .exp testscripts.
Example gdb.log output for the failure:
The testsuite sucessfully notices a failure to connect to port 2348.
It launches again with port 2349, which also fails. The testsuite
ignores this error and uses gdb to connect to the port - which succeeds.

Valgrind reports leaks like the below in various tests,
e.g. gdb.threads/attach-slow-waitpid.exp, gdb.ada/task_switch_in_core.exp, ...
Fix the leak by clearing the regcache when detaching from an inferior.
Note that these leaks are 'created' when GDB exits,
when the regcache::current_regcache is destroyed : the elements
of the forward_list are pointers, and the 'pointed to' memory is not
deleted by the forward_list destructor.
Nevertheless, fixing this leak is good as it makes a bunch of
tests 'leak clean'.
Also, it seems strange to keep a register cache for a process from
which GDB detached : it is not clear if this cache is still valid
after detach. And effectively, when clearing only the regcache,
(and not the frame cache), then the frame cache was still 'pointing'
at this regcache and was used when switching to the child process
in the test gdb.threads/watchpoint-fork.exp, which seems strange.
So, we solve the leak and avoid possible accesses to the regcache
and frame cache of the detached inferior, by clearing both the
regcache and the frame cache.
Tested on debian/amd64, natively, under Valgrind,
and with make check RUNTESTFLAGS="--target_board=native-gdbserver".
