2 * This program is used to generate definitions needed by
3 * assembly language modules.
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.
