From 0df01fd3d71481b5cc7aeea6a741b9fc3be15178 Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Fri, 21 May 2010 11:08:03 +0800 Subject: nios2: fix r15 issue for gcc4 The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15. It is necessary for gcc4 to work properly.
