This v2 series replaces, and extends the earlier series I posted here:
https://sourceware.org/pipermail/gdb-patches/2020-July/170288.html
The first 10 patches are the same as the previous series, while the
remaining 8 are new in this version of the series.
After this series the language_data base class is completely removed.
As I mentioned in the original patch series, I'm not 100% sure that
converting static data fields from language_data into virtual methods
on language_defn is the right approach, but getting rid of
language_data does feel like a good thing, so I pushed through and
completed the task.
I'd be interested in any feedback, do people think this is the right
approach, or are there any suggestions for a better approach.
Thanks,
Andrew

Convert the two language_data member variables la_name and
la_natural_name to virtual methods in language_defn struct called name
and natural_name respectively.
The virtual methods in the language_defn base class are pure virtual,
as every language must implement these, and as every language has a
unique name there's no sensible default here.
Given that every language must implement these methods I did wonder
about making this data passed into the base class constructor, but in
the end I went with the virtual method approach. I'm open to changing
this approach if people prefer the constructor approach.
During updating the calls to language_defn::name I found in
add_set_language_command a place where we took la_name and then
capitalised the first letter to create a language name that could be
used in the documentation string. I replaced this with a use of
natural_name instead as this seemed a better choice, in most cases
this will make no difference, as for most languages the natural_name
is just the name with the first character in upper case, but for some
languages, for example 'Open-CL' and 'Objective-C' this is not the
case.
In the case of asm_language the name is 'asm', while the natural_name
was previously 'assembly'. I changed the natural name to 'Assembly',
this makes the documentation string case above cleaner, however, this
will change the MI output for -var-info-expression, where the 'lang'
field will change from 'assembly' to 'Assembly'. It is possible this
could be a breaking change if a front-end is relying on the existing
name.

* [PATCHv2 04/18] gdb: Convert la_filename_extensions to a method

From: Andrew Burgess @ 2020-08-05 14:45 UTC (permalink / raw)
To: gdb-patches
Convert language_data::la_filename_extensions member variable to a
virtual method language_defn::filename_extensions.
The new method returns a vector of filename extensions, which means
that where previously we needed a NULL marker on the end of the list,
we can now discard this.
All of the old arrays that contained the extensions now become static
data within each languages filename_extensions method.
I've updated the single use of the filename_extensions method to make
use of this method returning a vector. And, just in case anyone
accidentally adds a NULL marked into a languages extensions list, I've
added a new assert in add_filename_language (symtab.c) to catch this.
gdb/ChangeLog:
* ada-lang.c (ada_extensions): Delete, moved into
ada_language::filename_extensions.
(ada_language_data): Remove la_filename_extensions initializer.

From: Andrew Burgess @ 2020-08-05 14:45 UTC (permalink / raw)
To: gdb-patches
Move the language_data::la_language member variable into the
langage_defn class.
I have not made the la_language member variable a method of
langage_defn simply because of the large number of places that
la_language is referenced throughout GDB. I have made the new member
variable constant though, so this should prevent accidental
assignment.
In the future we might consider converting la_language to a method,
but right now my goal is to remove the langage_data class, so I'm
happy to leave la_language as a constant member variable.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* ada-lang.c (ada_language_data): Remove la_language initializer.
* c-lang.c (c_language_data): Likewise.
(cplus_language_data): Likewise.
(asm_language_data): Likewise.
(minimal_language_data): Likewise.
* d-lang.c (d_language_data): Likewise.
* f-lang.c (f_language_data): Likewise.
* go-lang.c (go_language_data): Likewise.
* language.c (unknown_language_data): Likewise.
(auto_language_data): Likewise.
* language.h (language_data): Remove la_language field.
(language_defn::language_defn): Initialise la_language field.
(language_defn::la_language): New member variable.
* m2-lang.c (m2_language_data): Remove la_language field.
* objc-lang.c (objc_language_data): Likewise.
* opencl-lang.c (opencl_language_data): Likewise.
* p-lang.c (pascal_language_data): Likewise.
* rust-lang.c (rust_language_data): Likewise.

Convert language_data::string_lower_bound member variable to a virtual
method language_defn::string_lower_bound.
Over all of the languages we currently support there are currently
only two values for the lower bound, 0 or 1. I noticed that in all
cases, if a language has C style arrays then the lower bound is 0,
otherwise the lower bound is 1. So the default for the virtual method
in language.h makes use of this, which means languages don't have to
worry about providing a string_lower_bound method at all.
Except for Modula2. This language is defined to not have C style
arrays, but has a string_lower_bound index of 0, this behaviour is
maintained after this commit by having Modula2 be the only language
that overrides the string_lower_bound method.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* ada-lang.c (ada_language_data): Remove string_lower_bound
initializer.
* c-lang.c (c_language_data): Likewise.
(cplus_language_data): Likewise.

* objc-lang.c (objc_language_data): Remove string_lower_bound
initializer.
* opencl-lang.c (opencl_language_data): Likewise.

When store_sym_names_in_linkage_form_p was introduced in this commit:
commit 59cc4834e53565da1de4a7b615ed8890ed55c7da
Date: Tue Mar 27 08:57:16 2018 -0500
problem looking up some symbols when they have a linkage name
A special case was left behind for Go, however, this special case was
not really needed anymore, it could be handled by having
store_sym_names_in_linkage_form_p return the true for go, instead of
false.
This commit overrides store_sym_names_in_linkage_form_p for Go, and
then removes the special case. As store_sym_names_in_linkage_form_p
is only called once throughout GDB this should be perfectly safe.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* dwarf2/read.c (dwarf2_physname): Remove special case for
language_go.
* go-lang.c (go_language::store_sym_names_in_linkage_form_p): New
member function.

Convert language_data::la_range_check member variable to a virtual
method language_defn::range_checking_on_by_default.
Where the previous member variable was of type 'enum range_check', the
new member function returns a boolean that selects between range
checking being on or off. This removes the possibility of a language
having its default be the third enum state, range_check_warn.
There should be no user visible changes after this commit.

* ada-lang.c (ada_language_data): Remove la_range_check
initializer.
* c-lang.c (c_language_data): Likewise.
(cplus_language_data): Likewise.

From: Andrew Burgess @ 2020-08-05 14:45 UTC (permalink / raw)
To: gdb-patches
Convert language_data::la_case_sensitivity member variable to a virtual
method language_defn::case_sensitivity.
This is mostly straight forward. The only slight problem is that I
ended up deleting this comment from ada-lang.c:
/* Yes, Ada is case-insensitive, but that's not quite what this
means. */
However, as the comment (which has existed since Ada support was first
added to GDB) doesn't explain _why_ Ada sets case sensitivity to on
despite being a generally case insensitive language, this doesn't
really help me much.
If I understood _why_ the setting doesn't quite mean what it seems to
mean (at least as far as Ada is concerned) then I would extend the
comment on language_defn::case_sensitivity (in language.h) to include
the detail, and note how this impacts Ada. But as it stands I've just
deleted the comment for now.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* ada-lang.c (ada_language_data): Remove la_case_sensitivity
initializer.
* c-lang.c (c_language_data): Likewise.
(cplus_language_data): Likewise.
(asm_language_data): Likewise.
(minimal_language_data): Likewise.
* d-lang.c (d_language_data): Likewise.
* f-lang.c (f_language_data): Likewise.
(f_language::case_sensitivity): New member function.
* go-lang.c (go_language_data): Remove la_case_sensitivity
initializer.
* language.c (enum case_mode): Moved here from language.h.
(case_mode): Make static.
(show_case_command): Update for case_sensitivity being a method.
(set_case_command): Likewise.
(set_range_case): Likewise.
(unknown_language_data): Remove la_case_sensitivity initializer.
(auto_language_data): Likewise.
* language.h (case_mode): Delete, move enum declaration to
language.c.
(language_data): Delete la_case_sensitivity field.
(language_defn::case_sensitivity): New member function.
* m2-lang.c (m2_language_data): Remove la_case_sensitivity
initializer.
* objc-lang.c (objc_language_data): Likewise.
* opencl-lang.c (opencl_language_data): Likewise.
* p-lang.c (pascal_language_data): Likewise.

Convert language_data::la_exp_desc member variable to a virtual
method language_defn::expression_ops. The change of names brings this
method more into line with the existing varobj_ops method, that also
returns a table of function pointers.

To: gdb-patches
Convert language_data::la_op_print_tab member variable to a virtual
method language_defn::opcode_print_table. I changed the name in order
to make it clearer (I hope) what the method does.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* ada-lang.c (ada_language_data): Remove la_op_print_tab
initializer.
(ada_language::opcode_print_table): New member function.
* c-lang.c (c_language_data): Remove la_op_print_tab initializer.
(c_language::opcode_print_table): New member function.
(cplus_language_data): Remove la_op_print_tab initializer.
(cplus_language::opcode_print_table): New member function.
(asm_language_data): Remove la_op_print_tab initializer.
(asm_language::opcode_print_table): New member function.
(minimal_language_data): Remove la_op_print_tab initializer.
(minimal_language::opcode_print_table): New member function.
* d-lang.c (d_language_data): Remove la_op_print_tab initializer.
(d_language::opcode_print_table): New member function.
* expprint.c (print_subexp_standard): Update call to
opcode_print_table.
(op_string): Likewise.
* f-lang.c (f_language_data): Remove la_op_print_tab initializer.
(f_language::opcode_print_table): New member function.
* go-lang.c (go_language_data): Remove la_op_print_tab
initializer.
(go_language::opcode_print_table): New member function.

The language_data type, from which language_defn inherits, is now
empty, and this commit removes it.
Each language is updated to no longer create and use a language_data
struct.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* ada-lang.c (ada_language_data): Delete.

I'm going to take a look at rebasing and merging this series in the

Any last minute feedback?
Thanks,
Andrew
