   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.
