TARGET_WAITKIND_NO_RESUMED doesn't have an associated event thread, so
we shouldn't be referring to inferior_thread() assuming it points to
one.
This was caught on the multi-target branch, where we always switch to
no-thread-selected whenever we start handling an event, exactly to
catch places that incorrectly use "inferior_ptid/inferior_thread()"
without switching to the right event thread / target.
Here, on the branch, we assert in inferior_thread() because
TARGET_WAITKIND_NO_RESUMED doesn't have an associated event thread, so
inferior_ptid is still null_ptid.

* infrun.c (normal_stop): Also check for
TARGET_WAITKIND_NO_RESUMED before referring to inferior_thread().

This patch adds support for the older TYPE*SIZE typenames that are
still around in older code.
For implementation this currently reuses the kind mechanism, as under
gFortran the kind number is equivalent to the size, however, this is
not necessarily true for all compilers. If the rules for other
compilers are better understood then this code might need to be
improved slightly to allow for a distinction between size and kind,
however, adding this extra complexity now seems pointless.
gdb/ChangeLog:
* f-exp.y (direct_abs_decl): Handle TYPE*SIZE type names.
gdb/testsuite/ChangeLog:
* gdb.fortran/type-kinds.exp: Extend to cover TYPE*SIZE cases.
Adds support for the abs intrinsic function, this requires adding a
new pattern to the Fortran parser. Currently only float and integer
argument types are supported to ABS, complex is still not supported,
this can be added later if needed.
gdb/ChangeLog:
* f-exp.y: New token, UNOP_INTRINSIC.
(exp): New pattern using UNOP_INTRINSIC token.
(f77_keywords): Add 'abs' keyword.
* f-lang.c: Add 'target-float.h' and 'math.h' includes.
(value_from_host_double): New function.
(evaluate_subexp_f): Support UNOP_ABS.
gdb/testsuite/ChangeLog:
* gdb.fortran/intrinsics.exp: Extend to cover ABS.
Switch to using TYPE_CODE_CHAR for character types. This appears to
have little impact on the test results as gFortran uses the
DW_TAG_string_type to represent all character variables (as far as I
can see). The only place this has an impact is when the user casts a
variable to a character type, in which case GDB does now use the CHAR
type, and prints the variable as both a value and a character, for
example, before:
(gdb) p ((character) 97)
$1 = 97
and after:
(gdb) p ((character) 97)
$1 = 97 'a'
gdb/ChangeLog:
* f-lang.c (build_fortran_types): Use TYPE_CODE_CHAR for character
types.
gdb/testsuite/ChangeLog:
* gdb.fortran/type-kinds.exp: Update expected results.

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.
gdb/ChangeLog:
* expprint.c (dump_subexp_body_standard): Support UNOP_KIND.

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.
gdb/ChangeLog:
* f-lang.c (evaluate_subexp_f): New function.
(exp_descriptor_f): New global.
(f_language_defn): Use exp_descriptor_f instead of
exp_descriptor_standard.
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.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* f-exp.y (struct token): Add comments.
(dot_ops): Remove uppercase versions and the end marker.
(f77_keywords): Likewise.
(yylex): Use ARRAY_SIZE to iterate over dot_ops, assert all
entries in the dot_ops array are case insensitive, and use
strncasecmp to compare strings. Also some whitespace cleanup in
this area. Similar for the f77_keywords array, except entries in
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
constants '.TRUE.' and '.FALSE.'. Instead of listing both upper and
lowercase versions of these strings we now use strncasecmp.
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.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* f-exp.y (struct f77_boolean_val): Add comments.
(boolean_values): Remove uppercase versions, and end marker.
(yylex): Use ARRAY_SIZE for iterating over boolean_values array,
and use strncasecmp to achieve case insensitivity. Additionally,
perform whitespace cleanup around this code.
gdb/testsuite/ChangeLog:
* gdb.fortran/types.exp (test_logical_literal_types_accepted):

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.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (builtin_cd): rename of cd.
(cd): Override builtin.
* dwarf2.c (_bfd_dwarf2_find_symbol_bias): Check for a NULL symbol

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
currently shown as
Value.__init__ (val, [, type ])
in the documentation.
First, there is an extra comma, which I think we can remove in any
case.
Then, since the type parameter is not optional, I would not put in
between square brackets. Those usually indicate that something is
optional.
With this patch, it appears as:
Value.__init__ (val, type)

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
