But Altivec option not allowed with e500mc64, then some compiling errors occur like this: CC arch/powerpc/lib/xor_vmx.o arch/powerpc/lib/xor_vmx.c:1:0: error: AltiVec not supported in this target make[1]: *** [arch/powerpc/lib/xor_vmx.o] Error 1 make: *** [arch/powerpc/lib] Error 2 So we should restrict e500mc64 in altivec scenario.
