66 * This program is used to generate definitions needed by
67 * assembly language modules.
69 * This technique was first used in the OSF Mach kernel code:
70 * generate asm statements containing #defines,
71 * compile this file to assembler, and then extract the
72 * #defines from the assembly-language output.
