9e5e03df52 Use block_symbol in var_value_operation 
I noticed that var_value_operation takes a block and a symbol, and
most callers destructure a block_symbol to pass in.  It seems better
for this class to simply hold a block_symbol instead.

Tested on x86-64 Fedora 32.

9c79936b3d Use bound_minimal_symbol in var_msym_value_operation 
This changes var_msym_value_operation to use a bound_minimal_symbol
rather than separate minsym and objfile parameters.  The main benefit
of this is removing the possibly-confusing check_objfile overload for
a plain minimal symbol.

46157d77c3 gdb: move pascal_language into p-lang.h 
Move the pascal_language class declaration into the p-lang.h header
file.  This allows for the function implementations to be spread over
the different p-*.c files without the need for global trampoline
functions.

As a consequence of this change many of the Pascal value and type
printing helper functions have become member functions within the
pascal_language class.

There should be no user visible changes after this commit.

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).

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).

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.

cfeadda545 Fix build failure with macOS bison 
PR gdb/24060 points out a compilation failure of the C, Fortran and Pascal
parsers when they are built using the macOS system bison.  The bug is a name
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
that all languages use the same name.

This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

b926417afa Simple -Wshadow=local fixes 
This fixes all the straightforward -Wshadow=local warnings in gdb.  A
few standard approaches are used here:

* 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.

I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

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.

This commit is preparation for a later change, at this point there
should be no user visible change.

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).

b3f11165aa Centralize yacc interface names remapping (yyparse, yylex, yyerror, etc) 
This factors out all the yy-variables remapping to a single file,
instead of each parser having to do the same, with different prefixes.

With this, a parser just needs to define the prefix they want and
include yy-remap.h, which does the dirty job.

Note this renames the c_error, ada_error, etc. functions.  Writing the
remapping pattern as:

 #define yyerror GDB_YY_REMAP (error)

instead of:

 #define yyerror GDB_YY_REMAP (yyerror)

would have avoided the renaming.  However, that would be problematic
if we have a macro 'foo' in scope, when we write:

 #define yyfoo GDB_YY_REMAP (foo)

as that would expand 'foo'.

The c_yyerror etc. naming end ups indicating that this is a yacc
related function more clearly, so feels like a good change, anyway.

224c3ddb89 Add casts to memory allocation related calls 
Most allocation functions (if not all) return a void* pointing to the
allocated memory.  In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).

The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++".  I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style.  I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.

Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.

Only files built on x86 with --enable-targets=all are modified.  This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers.  Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.

I built-tested this with --enable-targets=all and reg-tested.

Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script.  I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

63e43d3aed DWARF: handle non-local references in nested functions 
GDB's current behavior when dealing with non-local references in the
context of nested fuctions is approximative:

  - code using valops.c:value_of_variable read the first available stack
    frame that holds the corresponding variable (whereas there can be
    multiple candidates for this);

  - code directly relying on read_var_value will instead read non-local
    variables in frames where they are not even defined.

This change adds the necessary context to symbol reads (to get the block
they belong to) and to blocks (the static link property, if any) so that
GDB can make the proper decisions when dealing with non-local varibale
references.

d12307c199 Replace the block_found global with explicit data-flow 
As Pedro suggested on gdb-patches@ (see
https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this
change makes symbol lookup functions return a structure that includes
both the symbol found and the block in which it was found.  This makes
it possible to get rid of the block_found global variable and thus makes
block hunting explicit.

f168693bc9 Remove CHECK_TYPEDEF, use check_typedef instead 
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit
annoying.  It makes unclear the fact that the "type" variables gets
overwritten.  It has actually bitten me a few times.  I think the
following, explicit form, is better.

  type = check_typedef (type);

This patches changes all instances of CHECK_TYPEDEF for an equivalent
call to check_typedef.  The bulk of the change was done with this sed:

  sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c

The ChangeLog was generated using David Malcom's generate_changelog.py.
I manually fixed those places where it gets the wrong function name,
hopefully all of them.

The patch was built-tested, and I ran a few smoke tests.

8aae434443 Fix pascal behavior for class fields with testcase 
Problem reported as PR pascal/17815

Part 1/3: Remember the case pattern that allowed finding a field of this.
File gdb/p-exp.y modified

  This is the fix in the pascal parser (p-exp.y),
to avoid the error that GDB does find normal variables
case insensitively, but not fields of this,
inside a class or object method.

Part 2/3: Add "class" option for pascal compiler
File gdb/testsuite/lib/pascal.exp

This part of the patch series is unchanged.
It adds class option to pascal compiler
which adds the required command line option to
accept pascal class types.

Part 3/3:
New file: gdb/testsuite/gdb.pascal/case-insensitive-symbols.exp
New file: gdb/testsuite/gdb.pascal/case-insensitive-symbols.pas

  Here is an updated version of this test, using Pedro's suggestions.
Test to check that PR 17815 is fixed.

fe978cb071 C++ keyword cleanliness, mostly auto-generated 
This patch renames symbols that happen to have names which are
reserved keywords in C++.

Most of this was generated with Tromey's cxx-conversion.el script.
Some places where later hand massaged a bit, to fix formatting, etc.
And this was rebased several times meanwhile, along with re-running
the script, so re-running the script from scratch probably does not
result in the exact same output.  I don't think that matters anyway.

3977b71f1d constify struct block in some places 
This makes some spots in gdb, particularly general_symbol_info, use a
"const struct block", then fixes the fallout.

The justification is that, ordinarily, blocks ought to be readonly.
Note though that we can't add "const" in the blockvector due to block
relocation.  This can be done once blocks are made independent of the
program space.

410a0ff2df Remove `expout*' globals from parser-defs.h 
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated.  This is the initial step to make our parser less
"globalized".

This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument.  It is big, and has been
reviewed at least 4 times, so I think everything is covered.
