POWER10 adds some return-oriented programming (ROP) instructions and
this patch adds support for them. You will notice that they are enabled
for POWER8 and later, not just POWER10 and later. This is on purpose.
This allows the instructions to be added to POWER8 binaries that can be
run on POWER8, POWER9 and POWER10 cpus. On POWER8 and POWER9, these
instructions just act as nop's.

These shouldn't be optional. The record form of vector instructions

Avoid shadowing a libiberty symbol (which oldish gcc warns about by
default), and allow building cleanly on 32-bit distros.

The arc fix in create_map avoiding signed overflow by casting an
unsigned char to unsigned int before shifting, shows one of the
dangers of blinding doing that. The problem in this case was that the
variable storing the value, newAuxRegister->address, was a long.
Using the unsigned cast meant that the 32-bit value was zero extended
when long is 64 bits. Previously we had a sign extension. Net result
was that comparisons in arcExtMap_auxRegName didn't match. Of course,
I could have cast the 32-bit unsigned value back to signed before
storing in a long, but it's neater to just use an unsigned int for the
address.

This patch fixes a problem with disassembly of branch instructions
for processors complying with PowerPC ISA versions prior to version
2.0, ie. those that use "y" bit branch taken hints. Many of the
extended bcctr and bclr mnemonics that should have disassembled with a
"-" suffix, ie. not taken, did not display the "-" due to the ordering
in powerpc_opcodes. I believe it's been that way from the original
85dcf36d72b commit of ppc-opc.c.
I've also added a BH field (optional) to a few opcodes. This gives
better disassembly in raw mode, showing the branch taken hint in the
mnemonic as is done for bc. It would be reasonable to add a BH
field to all bcctr, bclr, and bctar extended mnemonics but that runs
into a small difficulty: Currently we print all or none of the
optional operands. That means for example that "bgectr cr2" would
display as "bgectr cr2,0" if a BH field is added to bgectr.
* ppc-opc.c (XLBH_MASK): Subtract off BH field from BB_MASK.
(powerpc_opcodes): Reorder bcctr and bclr extended mnemonics
to favour printing of "-" branch hint when using the "y" bit.
Allow BH field on bc{ctr,lr,tar}{,l}{-,+}.

"mtfsb0 4*cr7+lt" doesn't make all that much sense, but unfortunately
glibc uses just that instead of "mtfsb0 28" to clear the fpscr xe bit.
So for backwards compatibility accept cr field expressions when
assembling mtfsb operands, but disassemble to a plain number.

The instruction mask bits should never overlap any of the operands,
nor should operand bits overlap, but some operands weren't checked.
This patch arranges to check the omitted operands, using a mask
returned by the operand->insert function. Some tweaking of various
insert functions is needed to support this: The error case must set
field bits.
Since I was looking at the insert functions, I tidied some dead code
and simplified some of the powerpc_operands entries.

Most optional operands to powerpc instructions use a default value of
zero, but there are a few exceptions. Those have been handled by
PPC_OPERAND_OPTIONAL_VALUE and an entry in the powerpc_operands table
for the default value, smuggled in the shift field. This patch
changes that to using the operand extract function to provide non-zero
defaults.
I've also moved the code determining whether optional operands are
provided or omitted, to the point the first optional operand is seen,
and allowed for the possibility of optional base register operands
in a future patch.
The patch does change the error you get on invalid assembly like
ld 3,4
You'll now see "missing operand" rather than
"syntax error; end of line, expected `('".

This is a relatively straightforward patch to improve support for the
IBM Gekko and IBM Broadway processors. Broadway is functionally
equivalent to the IBM 750CL, while Gekko's functionality is a subset
of theirs. The patch simplifies this reality and adds -mgekko and
-mbroadway as aliases for -m750cl. I didn't feel it was worth wasting
a PPC_OPCODE_* bit to differentiate Gekko. The patch adds a number of
simplified mnemonics for special purpose register access. Notably,
Broadway adds 4 additional IBAT and DBAT registers but these are not
assigned sequential SPR numbers.
