2 | * This program is used to generate definitions needed by | |

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. | |
