faeb9f13c1 gdb/fortran: add support for ASSOCIATED builtin 
This commit adds support for the ASSOCIATED builtin to the Fortran
expression evaluator.  The ASSOCIATED builtin takes one or two
arguments.

When passed a single pointer argument GDB returns a boolean indicating
if the pointer is associated with anything.

When passed two arguments the second argument should either be some a
pointer could point at or a second pointer.

If the second argument is a pointer target, then the result from
associated indicates if the pointer is pointing at this target.

If the second argument is another pointer, then the result from
associated indicates if the two pointers are pointing at the same
thing.

	* f-exp.y (f77_keywords): Add 'associated'.
	* f-lang.c (fortran_associated): New function.
	(evaluate_subexp_f): Handle FORTRAN_ASSOCIATED.

e92c8eb86d gdb/fortran: add parser support for lbound and ubound 
Add support for the LBOUND and UBOUND built in functions to the
Fortran expression parser.

Both support taking one or two arguments.  A single argument, which
must be an array, returns an array containing all of the lower or
upper bound data.

When passed two arguments, the second argument is the dimension being
asked about.  In this case the result is a scalar containing the lower
or upper bound just for that dimension.

Some examples of usage taken from the new test:

  # Given:
  #   integer, dimension (-8:-1,-10:-2) :: neg_array
  #
  (gdb) p lbound (neg_array)
  $1 = (-8, -10)
  (gdb) p lbound (neg_array, 1)
  $3 = -8
  (gdb) p lbound (neg_array, 2)
  $5 = -10

gdb/ChangeLog:

	* f-exp.y (UNOP_OR_BINOP_INTRINSIC): New token.
	(exp): New pattern using UNOP_OR_BINOP_INTRINSIC.
	(one_or_two_args): New pattern.
	(f77_keywords): Add lbound and ubound.
	* f-lang.c (fortran_bounds_all_dims): New function.
	(fortran_bounds_for_dimension): New function.
	(evaluate_subexp_f): Handle FORTRAN_LBOUND and FORTRAN_UBOUND.
	(operator_length_f): Likewise.
	(print_subexp_f): Likewise.
	(dump_subexp_body_f): Likewise.
	(operator_check_f): Likewise.
	* std-operator.def (FORTRAN_LBOUND): Define.

1b30f42106 Extract symbol-writing function from parsers 
I noticed that several parsers shared the same code to write a symbol
reference to an expression.  This patch factors this code out into a
new function.

Regression tested on x86-64 Fedora 32.

7c654b719d gdb/fortran: add symbol base comparison operators 
Fortran supports symbol based comparison operators as well as the
classic text based comparison operators, so we have:

   Text     | Symbol
   Operator | Operator
   ---------|---------
   .eq.     | ==
   .ne.     | /=
   .le.     | <=
   .ge.     | >=
   .gt.     | >
   .lt.     | <

This commit adds the symbol based operators as well as some tests.

gdb/ChangeLog:

	* f-exp.y (dot_ops): Rename to...
	(fortran_operators): ...this.  Add a header comment.  Add symbol
	based operators.
	(yylex): Update to use fortran_operators not dot_ops.  Remove
	special handling for '**', this is now included in
	fortran_operators.

gdb/testsuite/ChangeLog:

	* gdb.fortran/dot-ops.exp: Add new tests.

02c727013c Avoid side effects in expression lexers 
I noticed that some of the lexers were calling write_dollar_variable
from the lexer.  This seems like a bad practice, so this patch moves
the side effects into the parsers.

I tested this by re-running gdb.fortran and gdb.modula2; the Pascal
compiler on my machine seems not to work, so I couldn't test
gdb.pascal.

I note that the type-tracking in the Pascal is also incorrect, in that
a convenience variable's type may change between parsing and
evaluation (or even during the course of evaluation).

9dd02fc063 gdb: add tab completion of type field names for Fortran 
Add support for tab-completion on Fortran field names.  Consider this
test case:

 program test
   type my_type
      integer :: field_a
      integer :: other_field
      integer :: last_field
   end type my_type

   type(my_type) :: var

   print *, var
 end program test

And the GDB session before this patch:

 (gdb) start
 ...
 (gdb) p var%                   <- Trigger TAB completion here.
 Display all 200 possibilities? (y or n) n
 (gdb) p var%

And the GDB session with this patch:

 (gdb) start
 ...
 (gdb) p var%                   <- Trigger TAB completion here.
 field_a      last_field   other_field
 (gdb) p var%

The implementation for this is basically copied from c-exp.y, I
tweaked the parser patterns to be appropriate for Fortran, and it
"just worked".

gdb/ChangeLog:

	PR cli/26879
	* f-exp.y (COMPLETE): New token.
	(exp): Two new rules for tab-completion.
	(saw_name_at_eof): New static global.
	(last_was_structop): Likewise.
	(yylex): Set new variables, and return COMPLETE token at the end
	of the input stream in some cases.

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues 
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

1a0ea39913 gdb: move f_language class into a header file 
Moves the f_language class from f-lang.c into f-lang.h.  The benefit
of this is that functions declared in other f-*.c files can become
member functions without having to go through a level of indirection.

Some additional support functions have now become private member
functions of the f_language class, these are mostly functions that
then called some other function that was itself a member of the
language_defn class hierarchy.

There should be no user visible changes after this commit.

6b4c676cc7 gdb/fortran: add support for parsing array strides in expressions 
With this commit GDB now understands the syntax of Fortran array
strides, a user can type an expression including an array stride, but
they will only get an error informing them that array strides are not
supported.

This alone is an improvement on what we had before in GDB, better to
give the user a helpful message that a particular feature is not
supported than to just claim a syntax error.

Before:

  (gdb) p array (1:10:2, 2:10:2)
  A syntax error in expression, near `:2, 2:10:2)'.

Now:

  (gdb) p array (1:10:2, 2:10:2)
  Fortran array strides are not currently supported

Later commits will allow GDB to handle array strides correctly.

gdb/ChangeLog:

	* expprint.c (dump_subexp_body_standard): Print RANGE_HAS_STRIDE.
	* expression.h (enum range_type): Add RANGE_HAS_STRIDE.
	* f-exp.y (arglist): Allow for a series of subranges.
	(subrange): Add cases for subranges with strides.
	* f-lang.c (value_f90_subarray): Catch use of array strides and
	throw an error.
	* parse.c (operator_length_standard): Handle RANGE_HAS_STRIDE.

	* gdb.fortran/array-slices.exp: Add a new test.

2f1b18db86 gdb: Convert enum range_type to a bit field enum 
The expression range_type enum represents the following ideas:

  - Lower bound is set to default,
  - Upper bound is set to default,
  - Upper bound is exclusive.

There are currently 6 entries in the enum to represent the combination
of all those ideas.

In a future commit I'd like to add stride information to the range,
this could in theory appear with any of the existing enum entries, so
this would take us to 12 enum entries.

This feels like its getting a little out of hand, so in this commit I
switch the range_type enum over to being a flags style enum.  There's
one entry to represent no flags being set, then 3 flags to represent
the 3 ideas above.  Adding stride information will require adding only
one more enum flag.

I've then gone through and updated the code to handle this change.

There should be no user visible changes after this commit.

83228e93ef gdb/fortran: Introduce fortran-operator.def file 
Future commits will add more Fortran specific expression operators.

In preparation for these new operators, this commit adds a new
fortran-operator.def file similar to how GDB already has
ada-operator.def.

I've moved UNOP_KIND the Fortran specific operator I introduced in
commit 4d00f5d8f6 into this file, and renamed it to make it clearer
that the operator is Fortran specific.  I've then updated the Fortran
exp_descriptor table (exp_descriptor_f) to use entirely Fortran
specific functions that now handle UNOP_FORTRAN_KIND (the new name for
UNOP_KIND).

There should be no visible changes for standard users after this
commit, though for developers, the output when 'set debug expression
1' is now better, before:

28aaf3fdf9 Remove paren_depth global 
This removes the "paren_depth" global.  In most cases, it is made into
a static global in a given parser.  I consider this a slight
improvement, because it makes it clear that the variable isn't used
for communication between different modules of gdb.  The one exception
is the Rust parser, which already incorporates all local state into a
transient object; in this case the parser depth is now a member.

efbecbc143 gdb/fortran: Handle older TYPE*SIZE typenames 
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.

	* f-exp.y (direct_abs_decl): Handle TYPE*SIZE type names.

4d00f5d8f6 gdb/fortran: Add Fortran 'kind' intrinsic and keyword 
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.

	* expprint.c (dump_subexp_body_standard): Support UNOP_KIND.

dd9f2c763b gdb/fortran: Cleanup code for parsing logical constants 
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.

PR gdb/24060 points out a compilation failure of the C, Fortran and Pascal

clash between the VARIABLE token name and the VARIABLE enumerator in ui-out.h.

This patch renames VARIABLE in c-exp.y, f-exp.y and p-exp.y to DOLLAR_VARIABLE
to avoid the clash.  It also renames similar variables in other .y files so

* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
  including the special case of moving a declaration into a loop header.

69d340c684 Remove la_error 
While working on the parser code, I noticed that yyerror is exported
from each parser.  It is used by this code in parse.c:

   TRY
     {
       if (lang->la_parser (&ps))
         lang->la_error (NULL);
     }

However, it seems to me that la_error will never be called here,
because in every case, la_parser throws an exception on error -- each
implementation of yyerror just calls error.

So, this patch removes la_error and makes all the yyerror functions
static.  This is handy primarily because it makes it simpler to make
the expression parsers pure.

Tested by the buildbot.

aee1fcdf97 gdb: New API for tracking innermost block 
This commit is preparation for a later change, at this point there
should be no user visible change.

We currently maintain a global innermost_block which tracks the most
inner block encountered when parsing an expression.

This commit wraps the innermost_block into a new class, and switches all
direct accesses to the variable to use the class API.

edd079d9f6 Target FP: Use target format throughout expression parsing 
When parsing floating-point literals, the language parsers currently
use parse_float or some equivalent routine to parse the input string
into a DOUBLEST, which is then stored within a OP_DOUBLE expression
node.  When evaluating the expression, the OP_DOUBLE is finally
converted into a value in target format.

On the other hand, *decimal* floating-point literals are parsed
directly into target format and stored that way in a OP_DECFLOAT
expression node.  In order to eliminate the DOUBLEST, this patch
therefore unifies the handling of binary and decimal floating-
point literals and stores them both in target format within a
new OP_FLOAT expression node, replacing both OP_DOUBLE and
OP_DECFLOAT.

In order to store literals in target format, the parse_float
routine needs to know the type of the literal.  All parsers
therefore need to be changed to determine the appropriate type
(e.g. by detecting suffixes) *before* calling parse_float,
instead of after it as today.  However, this change is mostly
straightforward -- again, this is already done for decimal FP
today.

The core of the literal parsing is moved into a new routine
floatformat_from_string, mirroring floatformat_to_string.
The parse_float routine now calls either floatformat_from_string
or decimal_from_sting, allowing it to handle any type of FP
literal.

All language parsers need to be updated.  Some notes on
specific changes to the various languages:

- C: Decimal FP is now handled in parse_float, and no longer
  needs to be handled specially.

- D: Straightforward.

- Fortran: Still used a hard-coded "atof", also replaced by
  parse_float now.  Continues to always use builtin_real_s8
  as the type of literal, even though this is probably wrong.

- Go: This used to handle "f" and "l" suffixes, even though
  the Go language actually doesn't support those.  I kept this
  support for now -- maybe revisit later.  Note the the GDB
  test suite for some reason actually *verifies* that GDB supports
  those unsupported suffixes ...

- Pascal: Likewise -- this handles suffixes that are not
  supported in the language standard.

- Modula-2: Like Fortran, used to use "atof".

- Rust: Mostly straightforward, except for a unit-testing hitch.
  The code use to set a special "unit_testing" flag which would
  cause "rust_type" to always return NULL.  This makes it not
  possible to encode a literal into target format (which type?).
  The reason for this flag appears to have been that during
  unit testing, there is no "rust_parser" context set up, which
  means no "gdbarch" is available to use its types.  To fix this,
  I removed the unit_testing flag, and instead simply just set up
  a dummy rust_parser context during unit testing.

- Ada: This used to check sizeof (DOUBLEST) to determine which
  type to use for floating-point literal.  This seems questionable
  to begin with (since DOUBLEST is quite unrelated to target formats),
  and in any case we need to get rid of DOUBLEST.  I'm now simply
  always using the largest type (builtin_long_double).

3b22433085 Change {lookup,make}_reference_type API 
Parameterize lookup_reference_type() and make_reference_type() by the kind of
reference type we want to look up. Create two wrapper functions
lookup_{lvalue,rvalue}_reference_type() for lookup_reference_type() to simplify
the API. Change all callers to use the new API.
