   2 * This program is used to generate definitions needed by
   3 * assembly language modules.
   4 *
   5 * We use the technique used in the OSF Mach kernel code:
   6 * generate asm statements containing #defines,
   7 * compile this file to assembler, and then extract the
   8 * #defines from the assembly-language output.
