From 70c6edb3bcb97887f004515f17dd247657177cb5 Mon Sep 17 00:00:00 2001 From: Andreas Schwab Date: Mon, 30 Dec 2013 15:31:17 +0100 Subject: powerpc: Add vr save/restore functions commit 8fe9c93e7453e67b8bd09f263ec1bb0783c733fc upstream. GCC 4.8 now generates out-of-line vr save/restore functions when optimizing for size. They are needed for the raid6 altivec support.
