I just want to imply the use of optimized hweight*() routines to kbuild system. In other word I want to tell the kbuild system the condition of "defined(__alpha_fix__) && defined(__alpha_cix__)".
So I suggested to add previous patch and write below lines in arch/alpha/Kconfig
config GENERIC_HWEIGHT bool default y if !ALPHA_EV6 && !ALPHA_EV67
Also, I wonder why there are such gcc builtin definition in kernel code. Even if the gcc built with the support architecture extensions like CIX and FIX, It doesn't mean the vmlinux built by that gcc always run on those machines.
