nios2: fix div64 issue for gcc4

2010-05-28T14:56:03Z

This patch fixes the run-time error on div64 when built with gcc4, which was reported by jhwu0625 on nios forum. It merges math support from libgcc of gcc4. This patch is copied from nios2-linux. It works with both gcc3 and gcc4. The old mult.c, divmod.c and math.h are removed. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt

nios2: fix r15 issue for gcc4

2010-05-28T14:56:03Z

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. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt
