This commit is preparation work for the next commit, and by itself
makes no user visible change to GDB. I've split this work into a
separate commit in order to make code review easier.
This commit adds a new field 'la_is_string_type_p' to the language
struct, this predicate will return true if a type is a string type for
the given language.
Some languages already have a "is this a string" predicate that I was
able to reuse, while for other languages I've had to add a new
predicate. In this case I took inspiration from the value printing
code for that language - what different conditions would result in
printing something as a string.
A default "is this a string" method has also been added that looks for
TYPE_CODE_STRING, this is the fallback I've used for a couple of
languages.
In this commit I add the new field and initialise it for each
language, however at this stage the new field is never used.

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.
gdb/ChangeLog:
Update copyright year range in all GDB files.
-fsanitize=undefined complains about using operator~ on various enum
types that are used with DEF_ENUM_FLAGS_TYPE. This patch fixes these
problems by explicitly setting the base type for these enums to
unsigned. It also adds a static assert to enum_flags to ensure that
future enums used this way have an unsigned underlying type.

This patch adds *basic* support for C++ to the compile feature. It does
most simple type conversions, including everything that C compile does and
your basic "with-classes" type of C++.
I've written a new compile-support.exp support file which adds a new test
facility for automating and simplifying "compile print" vs "compile code"
testing. See testsuite/lib/compile-support.exp and CompileExpression
for more on that. The tests use this facility extensively.
This initial support has several glaring omissions:
- No template support at all
I have follow-on patches for this, but they add much complexity
to this "basic" support. Consequently, they will be submitted separately.
- Cannot print functions
The code template needs tweaking, and I simply haven't gotten to it yet.
- So-called "special function" support is not included
Using constructors, destructors, operators, etc will not work. I have
follow-on patches for that, but they require some work because of the
recent churn in symbol searching.
- There are several test suite references to "compile/1234" bugs.
I will file bugs and update the test suite's bug references before pushing
these patches.
The test suite started as a copy of the original C-language support, but
I have written tests to exercise the basic functionality of the plug-in.
I've added a new option for outputting debug messages for C++ type-conversion
("debug compile-cplus-types").

This patch changes structs compile_instance and compile_c_instance into
classes.
Because of the nature of the change, there are a number of unavoidably
mechanical changes buried in here, such as turning variable access of the
POD struct into method calls, removing the struct keyword, and changing
access of the plugin from "c_plugin->operation()" to
"plugin ().operation ()".
There is one "non-trivial" change associated with this patch, though.
The type cache and symbol error maps have been moved into the base class,
believing these facilities would be used other language implementations.
[They are indeed re-used by C++.]

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.

Currently dwarf2read.c will pass the CU's language to
c_type_print_args -- but this doesn't affect all aspects of type
printing, because some code in c-typeprint.c refers to
current_language.
This patch threads the language through more of the type printing
code, adding an overload to c_type_print. Some uses of
current_language remain, but now they are only in top-level functions.

PR rust/21484 notes that watch -location does not work with Rust:
(gdb) watch -location a
syntax error in expression, near `) 0x00007fffffffe0f4'.
update_watchpoint tries to tell gdb that the new expression it creates
has C syntax:
/* The above expression is in C. */
b->language = language_c;
However, update_watchpoint doesn't actually use this language when
re-parsing the expression.
Originally I was going to fix this by saving and restoring the
language in update_watchpoint, but this regressed
gdb.dlang/watch-loc.exp, because the constructed expression actually
has D syntax (specifically the name is not parseable by C).
Next I looked at directly constructing an expression, and not relying
on the parser at all; but it seemed to me that upon a re-set, we'd
want to reparse the type, and there is no existing API to do this
correctly.
So, in the end I made a hook to let each language choose what
expression to use. I made all the languages other than Rust use the C
expression, because that is the status quo ante. However, this is
probably not truly correct. After this patch, at least, it is easy to
correct by someone who knows the language(s) in question.
Regtested by the buildbot.

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.

This final patch adds the new "compile" command and subcommands, and
all the machinery needed to make it work.
A shared library supplied by gcc is used for all communications with
gcc. Types and most aspects of symbols are provided directly by gdb
to the compiler using this library.
gdb provides some information about the user's code using plain text.
Macros are emitted this way, and DWARF location expressions (and
bounds for VLA) are compiled to C code.
This hybrid approach was taken because, on the one hand, it is better
to provide global declarations and such on demand; but on the other
hand, for local variables, translating DWARF location expressions to C
was much simpler than exporting a full compiler API to gdb -- the same
result, only easier to implement, understand, and debug.
In the ordinary mode, the user's expression is wrapped in a dummy
function. After compilation, gdb inserts the resulting object code
into the inferior, then calls this function.
Access to local variables is provided by noting which registers are
used by location expressions, and passing a structure of register
values into the function. Writes to registers are supported by
copying out these values after the function returns.
This approach was taken so that we could eventually implement other
more interesting features based on this same infrastructure; for
example, we're planning to investigate inferior-side breakpoint
conditions.

1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
of FT_INTEGER fundamental type for array range index type.
(decode_base_type): Use builtin types of current_gdbarch
instead of fundamental types.
* dwarf2read.c (struct dwarf2_cu): Remove ftypes member.
(read_file_scope): Do not initialize ftypes member.
(dwarf_base_type, dwarf2_fundamental_types): Remove functions.
(read_array_type): Use builtin_type_int32 instead of FT_INTEGER
fundamental type for array range index type.
(read_tag_string_type): Likewise for string range index type.
Also, do not overwrite FT_CHAR type with new string type.
(read_base_type): If DW_AT_name is missing, create unnamed type
with given properties instead of looking for a fundamental type.
Create new types as TYPE_TARGET_TYPE for DW_ATE_address and
DW_ATE_complex_float types.
(read_subrange_type): Create new type to represent missing
DW_AT_type instead of looking for a fundamental type.
(die_type): Use builtin type to represent "void" instead of
looking for a fundamental type.
* stabsread.c (define_symbol): Use builtin types to represent
'r' and 'i' floating-point and integer constants.
* gdbtypes.c (lookup_fundamental_type): Remove.
* gdbtypes.h (lookup_fundamental_type): Remove prototype.
