Rust prefers to not specify the return type of a function when it is unit
(`()`). The type is also referred to as "void" in debuginfo but not in actual
usage, so we should never be printing "void" when the language is Rust.

When a Python script tries to create a breakpoint but fails to do so,
gdb.Breakpoint.__init__ raises an exception and the breakpoint does not
exist anymore in the Python interpreter. However, GDB still keeps a
reference to the Python object to be used for a later hook, which is
wrong.
This commit adds the necessary cleanup code so that there is no stale
reference to this Python object. It also adds a new testcase to
reproduce the bug and check the fix.

Correct a MIPS16 relocation handling regression in GAS introduced with:
commit 177b4a6ad0
Author: Alexandre Oliva <aoliva@redhat.com>
Date: Mon Mar 18 18:56:18 2002 +0000
discussed at <https://sourceware.org/ml/binutils/2002-03/msg00345.html>,
which removed a preparatory call to `mips16_extended_frag' previously
made from `md_estimate_size_before_relax'. As a result the function is
never called with its `sec' parameter non-NULL and consequently all the
unsupported relocation checks within are dead and never trigger, causing
any unhandled relocations to silently resolve to 0. Unfortunately there
was no sufficient test suite coverage back then to catch this.
Remove all dead code then, and all the associated comments. Update the
remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass
the relocation section as the `sec' parameter and use it to mark frags
which require an external relocation, as extended. Finally handle any
outstanding MIPS16 relocations in `md_convert_frag' and report an error
since we don't support any except with percent operators.

All platforms on FreeBSD use a shared system call table, so use a
single XML file to describe the system calls available on each FreeBSD
platform.
Recent versions of FreeBSD include the identifier of the current
system call when reporting a system call entry or exit event in the
ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As
such, FreeBSD native targets do not use the gdbarch method to fetch
the system call code. In addition, FreeBSD register sets fetched via
ptrace do not include an equivalent of 'orig_rax' (on amd64 for
example), so the system call code cannot be extracted from the
available registers during a system call exit. However, GDB assumes
that system call catch points are not supported if the gdbarch method
is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch
method that throws an internal_error if it is ever invoked.
gdb/ChangeLog:
* configure.ac: Check for support for system call LWP fields on
FreeBSD.
* config.in, configure: Rebuild.
* data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml.
* fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]:

(fbsd_get_syscall_number): New function.
(fbsd_init_abi): Set XML system call file name.

* syscalls/freebsd.xml: New file.
Add a 'print_auxv_entry' method for FreeBSD ABIs that parses
FreeBSD-specific auxiliary vector entries and outputs a suitable
description using fprint_auxv_entry.
gdb/ChangeLog:
* fbsd-tdep.c: Include "auxv.h".
(fbsd_print_auxv_entry): New function.
(fbsd_init_abi): Install gdbarch "print_auxv_entry" method.
Different platforms have different meanings for auxiliary vector
entries. The 'print_auxv_entry' gdbarch method allows an architecture
to output a suitable description for platform-specific entries.
A fprint_auxv_entry function is split out of fprint_target_auxv.
This function outputs the description of a single auxiliary vector
entry to the specified file using caller-supplied formatting and
strings to describe the vector type.
The existing switch on auxiliary vector types is moved out of
fprint_target_auxv into a new default_print_auxv_entry function.
default_print_auxv_entry chooses an appropriate format and description
and calls fprint_single_auxv to describe a single vector entry.
This function is used as the default 'print_auxv_entry' gdbarch method.
fprint_target_auxv now invokes the gdbarch 'print_auxv_entry' method
on each vector entry.

* auxv.c (fprint_auxv_entry): New function.
(default_print_auxv_entry): New function.

into a new elfcore_grok_freebsd_note function. Add core note grok routines
for FreeBSD's psinfo and prstatus notes while here rather than depending

bfd/ChangeLog:

FreeBSD. Remove case for NT_FREEBSD_THRMISC.
(elfcore_grok_freebsd_psinfo): New function.

When configured with the default options, GDB currently fails to link,
due to an undefined reference to bfd_link_plugin_object_p, coming from
elflink.c:
#ifdef BFD_SUPPORTS_PLUGINS
|| (abfd->plugin_format == bfd_plugin_unknown
&& bfd_link_plugin_object_p (abfd))
#endif
This is because BFD_SUPPORTS_PLUGINS is always defined. It is its value
that determines whether plugin support is enabled or not.
bfd/ChangeLog:
* elflink.c: Check the value of BFD_SUPPORTS_PLUGINS rather
than its existance.
Some MIPS targets use a named section symbol rather than a symbol with
no name as is used with most ELF targets. When renaming sections, the
named section symbol needs to be renamed too.
Rather than fix this bug, I'd originally intended to just correct the
xfail added recently for update-1.o vs update4.o in update-section.exp,
using the same set of targets for the localize-hidden-1 mips xfail.
I'd extracted that target test into a new function, is_bad_symtab. It
turns out to be useful in readelf.exp too.

This patch moves most of the demangling logic out of
symbol_find_demangled_name into the various language_defn objects.
The simplest way to do this seemed to be to add a new method to
language_defn. This is shame given the existing la_demangle, but
given Ada's unusual needs, and the differing demangling options
between languages, la_demangle didn't seem to fit.
In order to make this work, I made enum language order-sensitive.
This helps preserve the current ordering of demangling operations.

PR gdb/16483 notes that the output of "info frame-filters" is quite
voluminous. In particular it prints an entry for each objfile, even if
only to say that the objfile does not have any associated frame filters.
I think it's better to only print output when there is a frame filter.
There's nothing worth doing with the no-frame-filter information, and
limiting the output makes it much more readable.

PR gdb/16483:
* gdb.python/py-framefilter.exp: Add "info frame-filter" test
before any filters are loaded.
Keep original microMIPS symbols in references from branch relocations so
that the ISA bit is retained and can be verified for validity in static
link. No need to update WRT MIPS16 symbols because we keep them all
anyway for other reasons.
gas/
* config/tc-mips.c (b_reloc_p): New function.
(mips_fix_adjustable): Also keep the original microMIPS symbol
referred from branch relocations.
* testsuite/gas/mips/branch-local-1.d: New test.
* testsuite/gas/mips/branch-local-n32-1.d: New test.
* testsuite/gas/mips/branch-local-n64-1.d: New test.
* testsuite/gas/mips/micromips@branch-misc-4-64.d: Update
relocations.
* testsuite/gas/mips/branch-local-1.s: New test source.
* testsuite/gas/mips/mips.exp: Run the new cases.
The code supporting -mspfp, -mdpfp, and -mfpuda options are in
sections of code that are commented as being for backward
compatibility only, and having no effect. However, they do have an
effect, enabling the SPX, DPX, and DPA instruction subclasses
respectively. This commit moves the code supporting these options
away from the comments indicating that they are dummy options, and
also fixes a small issue where -mnps400 had the additional effect
of enabling SPX instructions.
A couple of other minor edits (that make no functional change) are
also included.
gas/ChangeLog:
* config/tc-arc.c (options, md_longopts, md_parse_option):
Move -mspfp, -mdpfp and -mfpuda out of the sections for
dummy options. Correct erroneous enabling of SPFP
instructions when using -mnps400.
include/ChangeLog:
* opcode/arc.h: Make insn_class_t alphabetical again.
opcodes/ChangeLog:
* arc-opc.c: Correct description of availability of NPS400
features.
