2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite

Print instruction description as comment in disassembly with s390
architecture specific option "insndesc":
- For objdump it can be enabled with option "-M insndesc"
- In gdb it can be enabled with "set disassembler-options insndesc"
Since comments are not column aligned the output can enhanced for
readability by postprocessing using a filter such as "expand":
... | expand -t 8,16,24,32,40,80
Or when using in combination with objdump option --visualize-jumps:
... | expand | sed -e 's/ *#/\t#/' | expand -t 1,80
Note that the instruction descriptions add about 128 KB to s390-opc.o:

Prior to commit 0e3c1eebb2 nm output depended on the host unsigned
long when printing "negative" symbol values for 32-bit targets.
Commit 0e3c1eebb22 made the output match that seen with a 64-bit host
unsigned long. The fact that nm output changed depending on host is
of course a bug, but it is reasonable to expect 32-bit target output
is only 32 bits. So this patch makes 32-bit target output the same as
it was on 32-bit hosts prior to 0e3c1eebb2.

While working on gdb's .debug_names writer, I found a couple of small
bugs in binutils .debug_names dumping.
First, the DWARF spec (section 6.1.1.4.6 Name Table) says:
These two arrays are indexed starting at 1, [...]
I think it is clearer for binutils to follow this, particularly
because DW_IDX_parent refers to this number.
Second, I think the handling of an empty hash table is slightly wrong.
Currently the dumping code assumes there is always an array of hashes.
However, section 6.1.1.4.5 Hash Lookup Table says:
The optional hash lookup table immediately follows the list of
type signatures.
and then:
The hash lookup table is actually two separate arrays: an array of
buckets, followed immediately by an array of hashes.
My reading of this is that the hash table as a whole is optional, and
so the hashes will not exist in this case. (This also makes sense
because the hashes are not useful without the buckets anyway.)
This patch fixes both of these problems. FWIW I have some gdb patches
in progress that change gdb both to omit the hash table and to use
DW_IDX_parent.

Add support for jump visualization for the s390 architecture in
disassembly:
objdump -d --visualize-jumps ...
Annotate the (conditional) jump and branch relative instructions with
information required for jump visualization:
- jump: Unconditional jump / branch relative.
- condjump: Conditional jump / branch relative.
- jumpsr: Jump / branch relative to subroutine.
Unconditional jump and branch relative instructions are annotated as
jump.
Conditional jump and branch relative instructions, jump / branch
relative on count/index, and compare and jump / branch relative
instructions are annotated as condjump.
Jump and save (jas, jasl) and branch relative and save (bras, brasl)
instructions are annotated as jumpsr (jump to subroutine).
Provide instruction information required for jump visualization during
disassembly.
The instruction type is provided after determining the opcode.
For non-code it is set to dis_noninsn. Otherwise it defaults to
dis_nonbranch. No annotation is done for data reference instructions
(i.e. instruction types dis_dref and dis_dref2). Note that the
instruction type needs to be provided before printing of the
instruction, as it is used in print_address_func() to translate the
argument value into an address if it is assumed to be a PC-relative
offset. Note that this is never the case on s390, as
print_address_func() is only called with addresses and never with
offsets.
The target of the (conditional) jump and branch relative instructions
is provided during print, when the PC relative operand is decoded.
include/
* opcode/s390.h: Define opcode flags to annotate instruction
class information for jump visualization:
S390_INSTR_FLAG_CLASS_BRANCH, S390_INSTR_FLAG_CLASS_RELATIVE,
S390_INSTR_FLAG_CLASS_CONDITIONAL, and
S390_INSTR_FLAG_CLASS_SUBROUTINE.
Define opcode flags mask S390_INSTR_FLAG_CLASS_MASK for above
instruction class information.
Define helpers for common instruction class flag combinations:
S390_INSTR_FLAGS_CLASS_JUMP, S390_INSTR_FLAGS_CLASS_CONDJUMP,
and S390_INSTR_FLAGS_CLASS_JUMPSR.
