/*

 * 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.
