Thanks for the hints - I'll follow the procedure.

The list of CPUs I made up out of thin air - I always associate "alignement required" with RISC in general, but you are right, ppc is the oddball risc platform and does allow it. So remove ppc and ppc64, add alpha and hppa.

I wonder if it is worth to split the loop into three parts, head and tail doing slow unaligned compares, but the main part doing 32bit compares.

This could be used on all cpus, and should be faster if the main loop dominates the length, even on x86/amd64 cpus.
