/*
* 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).
