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.
Refactor i386fbsd_core_read_xcr0 to fetch and return a corresponding
x86_xsave_layout as well as xcr0 using the size of an existing
NT_X86_XSTATE core dump to determine the offsets via
i387_guess_xsave_layout. Use this to add an implementation of
gdbarch_core_xfer_x86_xsave_layout.
Use tdep->xsave_layout.sizeof_xsave as the size of the XSTATE register
set and only fetch/store the register set if this size is non-zero.

This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.
Rather than using the x86-specific register offset tables, use
register maps to describe the layout of the general purpose registers
fetched via PT_GETREGS. The sole user-visible difference is that
FreeBSD/amd64 will now report additional segment registers ($ds, $es,
$fs, and $gs) for both 32-bit and 64-bit processes.
As part of these changes, the FreeBSD x86 native targets no longer use
amd64-bsd-nat.c or i386-bsd-nat.c. Remove FreeBSD-specific register
handling (for $fs_base, $gs_base, and XSAVE state) from these files.
Similarly, remove the global x86bsd_xsave_len from x86-bsd-nat.c. The
FreeBSD x86 native targets use a static xsave_len instead.
While here, rework the probing of PT_GETXMMREGS on FreeBSD/i386.
Probe the ptrace op once in the target read_description method and
cache the result for the future similar to the way the status of XSAVE
support is probed in the read_description method. In addition, return
the proper xcr0 mask (X87-only) for old kernels or systems without
either XSAVE or XMM support.
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
This commits the result of running gdb/copyright.py as per our Start

gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
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.
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
