/*
 * This program is designed so that it can be both:
 * (1) Run on the native machine to generate assym.h
 * (2) Converted to assembly that genassym.awk will
 *     translate into the same assym.h as (1) does.
 * The second method is done as follows:
 *   m68k-xxx-gcc [options] -S .../genassym.c
 *   awk -f genassym.awk < genassym.s > assym.h
 *
 * Using actual C code here (instead of genassym.cf)
 * has the advantage that "make depend" automatically
 * tracks dependencies of this C code on the (many)
 * header files used here.  Also, the awk script used
 * to convert the assembly output to assym.h is much
 * smaller and simpler than sys/kern/genassym.sh.
 *
 * Both this method and the genassym.cf method have the
 * disadvantage that they depend on gcc-specific features.
 * This method depends on the format of assembly output for
 * data, and the genassym.cf method depends on features of
 * the gcc asm() statement (inline assembly).
