No functional changes. 2021-11-17 Uroš Bizjak 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.
