Subject: [gcc(refs/users/meissner/heads/work055)] Fix xxeval predicates.
Date: Wed,  9 Jun 2021 04:00:47 +0000 (GMT)	[thread overview]

commit 53d27f2255733909b7585eaaf0e6f769d944716d
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Wed Jun 9 00:00:28 2021 -0400

    Fix xxeval predicates.
    
    In doing the patch to move the XX* built-in functions from altivec.md to
    vsx.md, I noticed that the xxeval built-in function used the
    altivec_register_operand predicate.  Since it takes vsx registers, this
    might force the register allocate to issue a move when it could use a
    traditional floating point register.  This patch fixes that.

            * config/rs6000/vsx.md (xxeval): Use register_predicate instead of
            altivec_register_predicate.
