/*
 *  linux/arch/or32/kernel/or32_defs.c
 *
 *  or32 version
 *
 * This program is used to generate definitions needed by
 * assembly language modules.
 *
 * We use the technique used in the OSF Mach kernel code:
 * generate asm statements containing #defines,
 * compile this file to assembler, and then extract the
 * #defines from the assembly-language output.
