5 *
6 * We use the technique used in the OSF Mach kernel code:
7 * generate asm statements containing #defines,
8 * compile this file to assembler, and then extract the
9 * #defines from the assembly-language output.
10 *
11 * On sparc, thread_info data is static and TI_XXX offsets are computed by hand.
