// Purpose:      Definition generator for M5272C3 board.
// Description:  This file contains code that can be compiled by the target
//               compiler and used to generate machine specific definitions
//               suitable for use in assembly code.

// This program is used to generate definitions needed by
// assembly language modules.
//
// This technique was first 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.

#define DEFINE(sym, val) \
        asm volatile("\n\t.equ\t" #sym ",%0" : : "i" (val))
