clisp has some built-in knowledge about the Alpha CPUs. Comments say
     Code address range:    0x000000012xxxxxxx
     Malloc address range:  0x000000012xxxxxxx
                      and:  0x0000015555xxxxxx
     Shared libraries:      0x0000015555xxxxxx
     Virtual address limit: 0x0000040000000000

So, one of the things that you can do is to show what is special about your
CPU.
  $ uname -a
  $ cat /proc/cpuinfo

The other thing that you can do is to follow the hints in the section
"Hints for porting to new platforms" in unix/PLATFORMS.
