X-IsSubscribed: yes

Just two thoughts:

1. You probably know that 'cc -S foo.c' produces foo.s which is the
assembler output. Might be worthwhile examining how the experts who
wrote the C compiler handle all this. The output is usually quite
readable for someone prone to reading such things.

2. Rather than generating asm some developers generate C and run that
thru the C compiler. One advantage is you can leverage all the C code
optimization and debugging etc infrastructure and anything else you
can find on the C and ld etc man pages (e.g., PIC.)

But there's nothing wrong with learning assemblers and machine
languages. In the distant past I taught it for several years at Boston
University so, good luck!
