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.
