make error if CC_OPTIMIZE_FOR_SIZE is activated

Hi,

I am using a cross compiler, to make a kernel for the i.mx6dl. If I set CONFIG_CC_OPTIMIZE_FOR_SIZE=y the compiler stops with an error. If I unset this option, the kernel will be compiled correcly.

CC	drivers/mxc/gpu-viv/hal/kernel/gc_hal_kernel.o

drivers/mxc/gpu-viv/hal/kernel/gc_hal_kernel.c: In function 'gckKERNEL_Dispatch':

drivers/mxc/gpu-viv/hal/kernel/gc_hal_kernel.c:1160:9: error: 'node' may be used uninitialized in this function [-Werror=maybe-uninitialized]

cc1: all warnings being treated as errors

make[3]: *** [drivers/mxc/gpu-viv/hal/kernel/gc_hal_kernel.o] Error 1

make[2]: *** [drivers/mxc/gpu-viv] Error 2

make[1]: *** [drivers/mxc] Error 2

make: *** [drivers] Error 2

Kernel: 3.0.35 from LTIB L3.0.35_4.1.0_130816

Compiler: gcc version 4.7.2 (Sourcery CodeBench Lite 2012.09-63)

Any Ideas how I can compile with this option?

Regards,

Timo
