2 * Adapted from Linux v2.6.36 kernel: arch/powerpc/kernel/asm-offsets.c

4 * This program is used to generate definitions needed by
5 * assembly language modules.
6 *
7 * We use the technique used in the OSF Mach kernel code:
8 * generate asm statements containing #defines,
9 * compile this file to assembler, and then extract the
10 * #defines from the assembly-language output.
