arc: Add ARCHS release 310a tune variant.
Add mtune and mcpu options for ARCHS release 310a type CPU. The
mtune=release31a is designed to be used as an alternative to the
mcpu=hs4x_rel31 option.
ARCHS4x release 31a uses DSP instructions which are implemented a bit
different than mpy9. Hence, use safer mpy2 option.
gcc/
* config/arc/arc-arch.h (arc_tune_attr): Add
ARC_TUNE_ARCHS4X_REL31A variant.
* config/arc/arc.cc (arc_override_options): Tune options for
release 310a.
(arc_sched_issue_rate): Use correct enum.
(arc600_corereg_hazard): Textual change.
(arc_hazard): Add release 310a tunning.
* config/arc/arc.md (tune): Update and take into consideration new
tune option.
(tune_dspmpy): Likewise.
(tune_store): New attribute.
* config/arc/arc.opt (mtune): New tune option.
* config/arc/arcHS4x.md (hs4x_brcc0, hs4x_brcc1): New cpu units.
(hs4x_brcc_op): New instruction rezervation.
(hs4x_data_store_1_op): Likewise.
* config/arc/arc-cpus.def (hs4x_rel31): New cpu variant.
* config/arc/arc-tables.opt: Regenerate.
* config/arc/t-multilib: Likewise.
* doc/invoke.texi (ARC): Update mcpu and tune sections.
