[From comp.arch -John]
In article <GW5DMC@xds13.ferranti.com> peter@ficc.ferranti.com (peter da silva) writes:
The Thompson compiler is extremely hardware-independent and generates
good 68020, MIPS, and Crisp code.
Note that the code generator proper is hand-written for each of these
architectures. To quote the paper: "There is a considerable amount of
talk in literature about automating this part of the compiler with a
hardware description. Since this code generator is so small (less than
500 lines of C) and easy, it hardly seems worth the effort." I guess
this is less than a gcc hardware description anyway.
It also implements full ANSI standard C, not a subset.
Not correct. To quote the paper again: "The compiler implements ANSI C
with some restrictions and extensions." "Several of the poorer
features were left out."
This is just nit-picking. I also really liked the paper.
