i386: Introduce LEGACY_SSE_REGNO_P predicate
Introduce LEGACY_SSE_REGNO_P predicate to simplify a couple of places.
No functional changes.
2021-11-17 Uroš Bizjak <ubizjak@gmail.com>
gcc/ChangeLog:
* config/i386/i386.h (LEGACY_SSE_REGNO_P): New predicate.
(SSE_REGNO_P): Use LEGACY_SSE_REGNO_P predicate.
* config/i386/i386.c (zero_all_vector_registers):
Use LEGACY_SSE_REGNO_P predicate.
(ix86_register_priority): Use REX_INT_REGNO_P, REX_SSE_REGNO_P
and EXT_REG_SSE_REGNO_P predicates.
(ix86_hard_regno_call_part_clobbered): Use REX_SSE_REGNO_P
and LEGACY_SSE_REGNO_P predicates.
