[from darryl at ISM780C (Darryl Richman)]


Has anyone looked at some of the newer, more automated methods of code
generation. I built a small code generator based on some of the ideas by
Graham and Glanville, supporting Unary *, =, +, and Binary -. I built it
for the 68k in about 5 hours. This technique presupposes a linear
intermediate language, which you then parse with, say, a LALR(1) parser,
emitting coe (or not as appropriate) with each reduction. The productions
represent addressing modes and operations.


Oh, BTW, although YACC itself is owned by AT&T, isn't it the case that
the output from yacc owes nothing to them? I believe that you owe no
royalties for the use and distributions of /lib/yaccpar.
