1bc60e5624 x86-64: Display eiz for address with the addr32 prefix
In 64-bit mode, display eiz for address with the addr32 prefix and without
base nor index registers.  For

	mov -0xccddef(,%eiz,), %rax

disassembler now displays:

	67 48 8b 04 25 11 22 33 ff 	mov -0xccddef(,%eiz,1),%rax

instead of

	67 48 8b 04 25 11 22 33 ff 	addr32 mov 0xffffffffff332211,%rax

d7f449c026 x86: Don't display --32/--64/--x32 without BFD64
For 32-bit x86 assembler, --64 and --x32 are unsupported if BFD64 is
undefined.  Even if BFD64 is defined, --64 and --x32 still may not be
supported if x86-64 support isn't compiled in:

[hjl@gnu-hsw-1 gas]$ ./as-new --64 -o x.o x.s
Assembler messages:
Fatal error: no compiled in support for x86_64

Assembler messages:

undefined and runs code64-inval only if BFD64 is undefined.

05d0e962f0 R_PPC64_REL24_NOTOC support
R_PPC64_REL24_NOTOC is used on calls like "bl foo@notoc" to tell the
linker that linkage stubs for PLT calls or long branches can't use r2
for pic addressing.  Instead, new stubs that generate pc-relative
addresses are used.  One complication is that pc-relative offsets to
the PLT may need to be 64-bit in large programs, in contrast to the
toc-relative addressing used by older PLT linkage stubs where a 32-bit
offset is sufficient until the PLT itself exceeds 2G in size.

.eh_frame info to cover the _notoc stubs is yet to be implemented.

b8891f8d62 Add support for the C_SKY series of processors.
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants.  V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc.  There is support for bare-metal ELF targets and Linux with both glibc and uClibc.

This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics.  C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers.  (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

fa758a7046 PowerPC Improve support for Gekko & Broadway
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.

4174bfff8a x86-64: correct AVX512F vcvtsi2s{d,s} handling
Just like for their AVX counterparts and CVTSI2S{D,S}, a memory source
here is ambiguous and hence
- in source files should be qualified with a suitable suffix or operand
  size specifier (not doing so is an error in Intel mode, and will gain
  a diagnostic in AT&T mode in the future),
- in disassembly should be properly suffixed (the Intel operand size
  specifiers were emitted correctly already).

0458ca4440 Specify architecture for SPARC gas tests
A couple of SPARC gas tests FAIL on Solaris/SPARC (both
sparc-sun-solaris2.11 and sparcv9-sun-solaris2.11):

FAIL: sparc PAUSE
FAIL: sparc CBCOND
FAIL: sparc CFR
FAIL: sparc CRYPTO
FAIL: sparc HPC+VIS3
FAIL: sparc IMA
FAIL: sparc OSA2015 %mwait asr and MWAIT instruction
FAIL: sparc OSA2015 %mcdper asr
FAIL: sparc SPARC5 and VIS4.0
FAIL: OSA2015 crypto instructions
FAIL: SPARC6
FAIL: FPCMPSHL OSA2017 instructions
FAIL: OSA2017 ONADD/ONSUB/ONMUL/ONDIV instructions.
FAIL: OSA2017 RLE instructions
FAIL: sparc64 rdasr
FAIL: sparc64 rdpr
FAIL: sparc64 rdhpr
FAIL: sparc64 wrasr
FAIL: sparc64 wrpr

It turns out there's a common pattern here: failures happen for all
tests that use SPARC ISA extensions beyond sparcv9, e.g. for the sparc
PAUSE test:

regexp_diff match failure
regexp "^   0:  b7 80 40 02     wr  %g1, %g2, %pause$"
line   "   0:   b7 80 40 02     wr  %g1, %g2, %asr27"
[...]
regexp_diff match failure
regexp "^   8:  b7 80 20 08     pause  8$"
line   "   8:   b7 80 20 08     wr  8, %asr27"
[...]

The fix is easy, actually: just as the tests specify the ISA extension
to use as a gas flag, the same needs to be done for objdump.  For the
test above, which has -Av9v, this means passing -msparc:v9v to objdump.
Doing so makes all but two (unrelated; to be reported separately)
failures go away.

This doesn't happen on Linux/SPARC, where gas emits GNU object attributes
matching the hardcare capabilities used.  Since gas doesn't yet implement
Solaris-style object capabilites, the explicit -march is needed, but only
passed on Solaris.

Tested on both sparc-sun-solaris2.11 and sparcv9-sun-solaris2.11.
