From e22c357b3ec01c1141969ae81397d60d52e8c87b Mon Sep 17 00:00:00 2001 From: Doug Kwan Date: Thu, 29 May 2014 09:12:20 -0500 Subject: target-ppc: Allow little-endian user mode. This allows running PPC64 little-endian in user mode if target is configured that way. In PPC64 LE user mode we set MSR.LE during initialization.
