unpack_value_bitfield is already optimized-out/unavailable -aware:
(...) VALADDR points to the contents of VAL. If the VAL's contents
required to extract the bitfield from are unavailable/optimized
out, DEST_VAL is correspondingly marked unavailable/optimized out.
however, it is not considering the case of the value having no
contents buffer at all, as can happen through
allocate_optimized_out_value.

I find the following test fail when I test native aarch64 gdb with
arm program,
(gdb) PASS: gdb.base/attach-pie-noexec.exp: attach

warning: Selected architecture arm is not compatible with reported target architecture aarch64^M
Architecture `arm' not recognized.^M
The target architecture is set automatically (currently aarch64)^M
(gdb) FAIL: gdb.base/attach-pie-noexec.exp: set architecture arm
GDB thinks the target is aarch64, but it isn't. Nowadays, we are
using some entries AT_PHENT and AT_HWCAP in auxv to determine whether
the process is a 32-bit arm one or 64-bit aarch64 one, and get the
right gdbarch. However, in the process of parsing auxv (in
inf_ptrace_auxv_parse), the size of int and data pointer of
target_gdbarch is used. If debug program exists (in most of cases),
target_gdbarch is already set according to the debug program, which
is arm in my case. Then, GDB can parse auxv successfully. However,
in gdb.base/attach-pie-noexec.exp, the debug program is removed,
target_gdbarch is aarch64 when GDB parse auxv, so GDB can't parse
it successfully.
Instead of using auxv, we check the return value of ptrace NT_ARM_VFP.
If the program is an arm process, NT_ARM_VFP is OK, otherwise, error
is returned.
Additionally, we only return tdesc_arm_with_neon for arm process,
because neon is mandatory on ARMv8.

Many of the existing sparc tests fail in non-ELF targets (coff and
a.out) due to spurious differences in the expected results:
- Unlike ELF, a.out text sections are aligned to 2**3 and padded
accordingly. The padding instruction is a `nop' (01 00 00 00).
- Likewise, coff text sections are also aligned to 2**3 and padded
accordingly. However, the padding instruction in these targets is an
`illtrap 0' (00 00 00 00).
- Unlike ELF, a.out and coff binaries don't contain hardware
capabilities bits that could be used by BFD to determine the opcodes
architecture corresponding to the instructions encoded in the
objects (v9, v9a, v9b, v9c, etc). Consequently, in both a.out and
coff tests we would need to pass proper `-m sparc:vXXX' options when
invoking objdump before comparing results.
In order to fix these issues, the most obvious solution would be to have
three variants of .d files per impacted test. For example, for save.d
we would have: save-elf.d, save-aout.d and save-coff.d. Using the
`#source' directive, a single save.s file would provide the input for
all of them. However, this approach has the following problems:
- The #target and #notarget .d directives are very limited: they use
globs instead of regular expressions, and thus it is not possible (or
too messy) to use them to discriminate between elf, coff and a.out
sparc targets.
- It adds little or no value to have variants of all these tests for all
the target types, and it would be a burden to maintain them. Actually
the features tested in the spuriously failing tests (relatively modern
sparc instructions, registers and asis) are not really found in
running coff or a.out sparc systems.
This patch changes sparc.exp so it will run these tests only in
ELF-targets, using the more standard `is_elf_format' from
binutils-common.exp instead of the ad-hoc (and less convenient, as it
must be called before _every_ single elf-only test) sparc_elf_setup.
Incidentally, the patch also fixes the #name entry for save-args.d.
Tested in sparc*-*-linux-gnu, sparc-aout and sparc-coff targets.

Convert microMIPS branches and jumps whose delay slot would be filled by
a generated NOP instruction to the corresponding compact form where one
exists, in a manner similar to MIPS16 JR->JRC and JALR->JALRC swap.
Do so even where the transformation switches from a 16-bit to a 32-bit
branch encoding for no benefit in code size reduction, as this is still
advantageous. This is because a branch/NOP pair takes 2 pipeline slots
or a 2-cycle completion latency except in superscalar implementations.
Whereas a compact branch may or may not stall on its target fetch, so it
will at most have a 2-cycle completion latency and may have only 1 even
in scalar implementations, and in superscalar implementations it is
expected to have no worse latency as a branch/NOP pair has. Also it
won't stall and therefore take the extra latency cycle in the not-taken
case.
Technically this is the same as MIPS16 compaction: for the qualifying
instruction encodings the APPEND_ADD_COMPACT machine code generation
method is selected where APPEND_ADD_WITH_NOP otherwise would and tells
the code generator in `append_insn' to convert the regular form of an
instruction to its corresponding compact form. For this the opcode is
tweaked as necessary and the microMIPS opcode table is scanned for the
matching updated instruction. A non-$0 `rt' operand to BEQ and BNE
instructions is moved to the `rs' operand field of BEQZC and BNEZC
encodings as required.
Unlike with MIPS16 compaction however we need to handle out-of-distance
branch relaxation as well. We do this by deferring the generation of
any delay-slot NOP required to relaxation made in `md_convert_frag', by
converting the APPEND_ADD_WITH_NOP machine code generation to APPEND_ADD
where a relaxed instruction is recorded. Relaxation then, depending on
actual code produced, chooses between either using a compact branch or
jump encoding and emitting the NOP outstanding if no compact encoding is
possible.
For code simplicity's sake the relaxation pass is retained even if the
principle of preferring a compact encoding to a 16-bit branch/NOP pair
means, in the absence of out-of-range branch relaxation, that a single
compact branch machine code instruction will eventually be produced from
a given assembly source instruction.
