From 70a0f81412b0b18a6fd0bea960451bc6c2cca49a Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 29 Apr 2008 12:54:59 -0500 Subject: [PATCH] 85xx: Add -mno-spe to e500/85xx builds Newer gcc's might be configured to enable autovectorization by default. If we happen to build with one of those compilers we will get SPE instructions in random code. -mno-spe disables the compiler for automatically generating SPE instructions without our knowledge.
