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. | |
9 | * | |
10 | * On sparc, thread_info data is static and TI_XXX offsets are computed by hand. | |
