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
headers.
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.
