This patch serie adds support for the SPARC M8 processor to GCC.
The SPARC M8 processor implements the Oracle SPARC Architecture 2017.
- bmask* instructions are put in their own instruction type. It makes
little sense to have them in the same category than array
instructions.
- Similarly, VIS compare instructions are put in their own instruction
type. This is to better accommodate subtypes, which are not quite
the same than the subtypes of `visl' instructions.
- The introduction of a new `subtype' insn attribute in sparc.md
avoids the need for adjusting the instruction scheduler DFAs for
previous cpu models every time a new cpu is introduced.
- The full set of SPARC instructions used in sparc.md, and their
position in the type/subtype hierarchy, is documented in a comment.
This eases the modification of the DFA schedulers, and the addition
of new cpus.
- The M7 DFA scheduler is reworked:
+ To use the new type/subtype hierarchy.
+ The v3pipe insn attribute is no longer needed.
+ More accurate latencies for instructions.
+ The C4 core pipeline is documented in a comment in niagara7.md.
- Support for -mcpu=m8 (we are thus suggesting to abandon the niagaraN
denomination for M8 and later processors.)
- Support for a new VIS level, VIS4B, covering the new VIS
instructions introduced in OSA2017 and implemented in the M8. Also
built-ins.
- A M8 DFA scheduler:
+ Also based on the new type/subtype hierarchy.
+ The functional units in the C5 core are explicitly documented in a
comment in m8.md.

The patch I committed yesterday to remove some generated headers from
the source tree unfortunately has a dependency missing that is only
revealed when doing a cross-native or full Canadian cross build. The
gen* programs were missing a dependency on one of the generated

Fixed by adding an explicit dependency rule for GTM_H in the same way
as we do for TM_H.

This patch implements TARGET_FIXED_CONDITION_CODE_REGS on ARM.
We have two main cases to consider: in Thumb1 code there are no
condition code registers, so we simply return false. For other
cases we set the the first pointer to CC_REGNUM and the second to
VFPCC_REGNUM iff generating hard-float code.
Running the CSiBE benchmark I see a couple of cases (both in the same
file) where this feature kicks in, so it's not a major change.

* configure.ac [target=avr]: WARN instead of ERROR if avrxmega3
.rodata in flash test fails.
(HAVE_LD_AVR_AVRXMEGA3_RODATA_IN_FLASH): Define it if test passes.
* confgure: Regenerate.
* config.in: Regenerate.
* config/avr/avr.c (avr_asm_named_section)
[HAVE_LD_AVR_AVRXMEGA3_RODATA_IN_FLASH]: Only trigger
__do_copy_data for stuff in .rodata if flash_pm_offset = 0.
(avr_asm_init_sections): Same.

Advanced SIMD patterns are not predicable, thus they should not have
%? in their output templates. Found when auditing the code for
something else. This has been in my tree for sometime , bootstrapped
and regression tested on armhf for armv7ve+simd as the architectural
base.
Applied to trunk
<DATE> Ramana Radhakrishnan <ramana.radhakrishnan@arm.com>
* config/arm/neon.md (fma<VCVTF:mode>4): Remove %?.
(fma<VH:mode>4_intrinsic): Likewise.
(*fmsub<VCVTF:mode>4): Likewise.
(*fmsub<VH:mode>4_intrinsic): Likewise.
