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.

Add extended mnemonics specified in the z/Architecture Principles of
Operation [1] and z/Architecture Reference Summary [2], that were
previously missing from the opcode table.
The following added extended mnemonics are synonyms to a base mnemonic
and therefore disassemble into their base mnemonic:
jc, jcth, lfi, llgfi, llghi
The following added extended mnemonics are more specific than their base
mnemonic and therefore disassemble into the added extended mnemonic:
risbhgz, risblgz, rnsbgt, rosbgt, rxsbgt
The following added extended mnemonics are more specific than their base
mnemonic, but disassemble into their base mnemonic due to design
constraints:
notr, notgr
The missing extended mnemonic jl* conditional jump long flavors cannot
be added, as they would clash with the existing non-standard extended
mnemonic j* conditional jump flavors jle and jlh. The missing extended
mnemonic jlc jump long conditional is not added, as the related jl*
flavors cannot be added.
Note that these missing jl* conditional jump long flavors are already
defined as non-standard jg* flavors instead. While the related missing
extended mnemonic jlc could be added as non-standard jgc instead it is
forgone in favor of not adding further non-standard mnemonics.
The missing extended mnemonics sllhh, sllhl, slllh, srlhh, srlhl, and
srllh cannot be implemented using the current design, as they require
computed operands. For that reason the following missing extended
mnemonics are not added as well, as they fall into the same category of
instructions that operate on high and low words of registers. They
should better be added together, not to confuse the user, which of those
instructions are currently implemented or not.

The IBM z/Architecture Principle of Operation [1] specifies the last
operand(s) of some (extended) mnemonics to be optional. Align the
mnemonic definitions in the opcode table according to specification.
This changes the last operand of the following (extended) mnemonics to
be optional:
risbg, risbgz, risbgn, risbgnz, risbhg, risblg, rnsbg, rosbg, rxsbg
Note that efpc and sfpc actually have only one operand, but had
erroneously been defined to have two. For backwards compatibility the
wrong RR register format must be retained. Since the superfluous second
operand is defined as optional the instruction can still be coded as
specified.

This is a NOP change only relevant when reading the file or parsing it
with other tools.
opcodes/ChangeLog:
2015-09-09 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* s390-opc.c: Add OP32 definition.
* s390-opc.txt: Reduce the opcode padding of some extended
mnemonics from 6 to the actual length (which is 4).
- 32 128 bit vector registers (overlapping with the existing 16 64 bit
floating point registers)
- vector double instructions
- vector integer instructions
- scalar vector instructions (allowing to have more floating point
registers for scalar operations)
- vector string instructions
gas/ChangeLog:
* config/tc-s390.c (struct pd_reg): Remove.
(pre_defined_registers): Remove.
(REG_NAME_CNT): Remove.
(reg_name_search): Calculate the register number instead of doing
a lookup.
(register_name, tc_s390_regname_to_dw2regnum): Adopt to the new
reg_name_search signature.
(s390_parse_cpu): Support the new arch string z13.
(s390_insert_operand): Support for vector registers with the extra
field for the fifth bit of each vector register operand.
(md_gather_operand): Adjust to the new handling of optional
parameters.
* doc/as.texinfo: Document the z13 cpu string.
gas/testsuite/ChangeLog:
* gas/s390/esa-g5.d: Add a variant without the optional operand.
* gas/s390/esa-g5.s: Likewise.
* gas/s390/esa-z9-109.d: Likewise.
* gas/s390/esa-z9-109.s: Likewise.
* gas/s390/zarch-z9-109.d: Likewise.
* gas/s390/zarch-z9-109.s: Likewise.
* gas/s390/zarch-z10.d: For variants with a zero optional argument
it is not dumped by objdump anymore.
* gas/s390/zarch-zEC12.d: Likewise.
* gas/s390/zarch-z13.d: New file.
* gas/s390/zarch-z13.s: New file.
* gas/s390/s390.exp: Run the test for the z13 files.
include/opcode/ChangeLog:
* s390.h (s390_opcode_cpu_val): Add S390_OPCODE_Z13.
ld/testsuite/ChangeLog:
* ld-s390/tlsbin.dd: The nopr register operand is optional and not
printed if 0 anymore.
opcodes/ChangeLog:
* s390-dis.c (s390_extract_operand): Support vector register
operands.
(s390_print_insn_with_opcode): Support new operands types and add
new handling of optional operands.
* s390-mkopc.c (s390_opcode_mode_val, s390_opcode_cpu_val): Remove
and include opcode/s390.h instead.
(struct op_struct): New field `flags'.
(insertOpcode, insertExpandedMnemonic): New parameter `flags'.
(dumpTable): Dump flags.
(main): Parse flags from the s390-opc.txt file. Add z13 as cpu
string.
* s390-opc.c: Add new operands types, instruction formats, and
instruction masks.
(s390_opformats): Add new formats for .insn.
* s390-opc.txt: Add new instructions.
* s390-opc.txt: Fix description for fiebra, fidbra, and fixbra.
For the load fp integer instructions only the suppression flag was
new with z196 version.
