Move some declarations related to the "quit" machinery from defs.h to
event-top.h. Most of the definitions associated to these declarations
are in event-top.c. The exceptions are `quit()` and `maybe_quit()`,
that are defined in utils.c. For consistency, move these two
definitions to event-top.c.
Include "event-top.h" in many files that use these things.

The recent change to how unsized Rust values are printed included a
small regression from past behavior. Previously, a slice's type would
be printed, like:
(gdb) print slice
$80 = &[i32] [3]
The patch changed this to just
(gdb) print slice
$80 = [3]
This patch restores the previous behavior.

Now that defs.h, server.h and common-defs.h are included via the
`-include` option, it is no longer necessary for source files to include
them. Remove all the inclusions of these files I could find. Update
the generation scripts where relevant.

This patch rewrites the handling of slice types in Rust.
More recent versions of the Rust compiler changed how unsized types
were emitted, letting gdb inspect them more nicely. However, gdb did
not do this, and in fact treated all such types as if they were slices
of arrays, which is incorrect.
This patch rewrites this handling and removes the restriction that
unsized types must be array slices. I've added a comment explaining
how unsized types are represented to rust-lang.c as well.
I looked into a different approach, namely changing the DWARF reader
to fix up slice types to have a dynamic type. However, the approach
taken here turned out to be simpler.
Tested on x86-64 Fedora 38 with a variety of Rust compiler versions.

This changes rust_structop::evaluate_funcall to only search for
functions.
|
|
This changes lookup_symbol and associated APIs to accept
domain_search_flags rather than a domain_enum.
Note that this introduces some new constants to Python and Guile. I
chose to break out the documentation patch for this, because the
internals here do not change until a later patch, and it seemed
simpler to patch the docs just once, rather than twice.

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

This patch exposes rust_slice_type_p and introduces
rust_slice_to_array, in preparation for subsequent patches that will
need these.

This moves rust_language::lookup_symbol_nonlocal to rust-lang.c.
There's no need to have it in rust-lang.h and moving it lets us avoid
adding new includes in a later patch.

After finding this code in buildsym_compunit::finish_block_internal:
...
ftype->set_fields
((struct field *)
TYPE_ALLOC (ftype, nparams * sizeof (struct field)));
...
and fixing PR30810 by using TYPE_ZALLOC, I wondered if there were more
locations that needed fixing.
I decided to make things easier to spot by factoring out a new function
alloc_fields:
...
/* Allocate the fields array of this type, with NFIELDS elements. If INIT,
zero-initialize the allocated memory. */
void
type::alloc_fields (unsigned int nfields, bool init = true);
...
where:
- a regular use would be "alloc_fields (nfields)", and
- an exceptional use that needed no initialization would be
"alloc_fields (nfields, false)".
Pretty soon I discovered that most of the latter cases are due to
initialization by memcpy, so I added two variants of copy_fields as well.
After this rewrite there are 8 uses of set_fields left:
...
gdb/coffread.c: type->set_fields (nullptr);
gdb/coffread.c: type->set_fields (nullptr);
gdb/coffread.c: type->set_fields (nullptr);
gdb/eval.c: type->set_fields
gdb/gdbtypes.c: type->set_fields (args);
gdb/gdbtypes.c: t->set_fields (XRESIZEVEC (struct field, t->fields (),
gdb/dwarf2/read.c: type->set_fields (new_fields);
gdb/dwarf2/read.c: sub_type->set_fields (sub_type->fields () + 1);
...
These fall into the following categories:
- set to nullptr (coffread.c),
- type not owned by objfile or gdbarch (eval.c), and
- modifying an existing fields array, like adding an element at the end or
dropping an element at the start (the rest).
Tested on x86_64-linux.

PR rust/30090 points out that a certain "finish" in a Rust program
will cause gdb to crash. This happens due to some confusion about
field indices in rust_language::print_enum. The fix is to use
value_primitive_field so that the correct type can be passed; other
spots in rust-lang.c already do this.
Note that the enclosed test case comes with an xfail. This is needed
because for this function, rustc doesn't follow the platform ABI.

This introduces the set_lval method on value, one step toward removing
deprecated_lval_hack. Ultimately I think the goal should be for some
of these set_* methods to be replaced with constructors; but I haven't
done this, as the series is already too long. Other 'deprecated'
methods can probably be handled the same way.

The next patch will want to do language->print_type(type, ...), to
print a type in a given language, avoiding a dependency on the current
language. That doesn't work correctly currently, however, because
most language implementations of language_defn::print_type call
c_print_type without passing down the language. There are two
overloads of c_print_type, one that takes a language, and one that
does not. The one that does not uses the current language, defeating
the point of calling language->print_type()...
This commit removes the c_print_type overload that does not take a
language, and adjusts the codebase throughout to always pass down a
language. In most places, there's already an enum language handy.
language_defn::print_type implementations naturally pass down
this->la_language. In a couple spots, like in ada-typeprint.c and
rust-lang.c there's no enum language handy, but the code is written
for a specific language, so we just hardcode the language.
In gnuv3_print_method_ptr, I wasn't sure whether we could hardcode C++
here, and we don't have an enum language handy, so I made it use the
current language, just like today. Can always be improved later.

This adds an implementation of the value_print method to Rust. As
described in PR rust/22254, this removes a bit of weird-looking output
from some "print"s -- because c_value_print is bypassed. I don't have
a test for the bug that inspired this patch, because I only know how
to reproduce it when using a relatively old Rust compiler. However,
the new "cast-printing" code in value_print is required, because
omitting this causes some existing tests to fail.

The current nightly Rust compiler (aka 1.61) added better DWARF
representation for unsized types. Fixing this is PR rust/21466; but
the code is actually the same as what is required to make slice
printing more useful, which is PR rust/23871. This patch implements
this. I tested this against various Rust compilers: 1.48, current
stable, current beta, and current nightly.
