From 3bfc2fa3f4d5c9f86fa811ae170bfd2bee875030 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Fri, 9 Jan 2015 13:50:08 +0000 Subject: [PATCH] RTEMS: Fix MPC8540 multilibs for PowerPC GCC generates SPE instructions even if -msoft-float is specified. Explicitly add -mno-spe to prevent generation of SPE instructions. This multilib variant must not lead to a usage of the SPE. gcc/ChangeLog * config/rs6000/t-rtems: Add -mno-spe to soft-float multilib for MPC8540.
