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

  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.
