Olaf Hering f48b8296b3 [PATCH] powerpc32: Set cpu explicitly in kernel compiles ... Compile the 32bit kernel with -mcpu=powerpc. This reduces the imagesize when a compiler is used that defaults to -mtune=power4. It inserts lots of nops to please the 64bit cpu instruction scheduling. But all these nops are not needed for 32bit kernels. Example with SLES10 gcc 4.1.0 and arch/powerpc/configs/pmac32_defconfig: vmlinux vmlinux.strip vmlinux.gz -O2 4980515 4187528 1846829 -Os 4618801 3827084 1673333 -O2 -mcpu=powerpc 4738851 3945868 1816253 -Os -mcpu=powerpc 4532785 3741068 1664688 Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Paul Mackerras <paulus@samba.org>		2006-04-13 09:38:33 -07:00
