From: Michael Meissner <meissner@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/meissner/heads/work056)] Fix xxeval predicates. Date: Fri, 18 Jun 2021 04:24:01 +0000 (GMT) [thread overview] Message-ID: <20210618042401.E68DA385700D@sourceware.org> (raw) https://gcc.gnu.org/g:d64d7661e35eb43d8014154f1700e69f4d979ce1 commit d64d7661e35eb43d8014154f1700e69f4d979ce1 Author: Michael Meissner <meissner@linux.ibm.com> Date: Fri Jun 18 00:23:40 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. gcc/ 2021-06-18 Michael Meissner <meissner@linux.ibm.com> * config/rs6000/vsx.md (xxeval): Use register_predicate instead of altivec_register_predicate.
