  21 # If we're cross-compiling, we use the cross-compiler to translate
  22 # print_offsets.c into an assembly file and then awk to translate this
  23 # file into offsets.h.  This avoids having to use a simulator to
  24 # generate this file.  This is based on an idea suggested by Asit
  25 # Mallick.  If we're running natively, we can of course just build
  26 # print_offsets and run it. --davidm
