Hmmm ... Do you perhaps want a P4 P-Code to 386 translation scheme instead? I'm assuming here that P4000 is some derivative of the P4. Since you already have a front-end, it may be easier to translate it's output to 386 as a separate program, instead of modifying the existing "front-end". Perhaps someone here may know of existing code to perform such a translation or at least know where to find decent documentation of the P4 P-Code (BTW, if so, I may be interested too;-). Joe.

Didn\'t you go to school? :) Weren\'t you ordered to make a simple compiler which accepted a Pascal subset and generated machine code?

I will tell you why do I want this translation scheme. I am involved in a project in which one of its steps is taking a compiler of a language called \'LC99\' (it is very close to Pascal or Algol) which actually generates P-Code (from Pascal compiler P4000) and change it in order to make it generates i386 code. It\'s the first time I make a pure back-end (I\'ve been always working on front-ends, which make me happier :). I am not interested in optimizations, because my project has only academical purposes (it\'s a visualizator of memory implemented over GDB).

Of course, implementation of GPC (front-end+Tree+RTL+back-end) crashes with I want to get (lex,parser,semant-->code). I knew it. But I thought any of you had some experience in something like this.

Many thanks to Marcel, Frank Heckenbach, Waldek Hebisch, Russell Whitaker, Maurice Lombardi and The African Chief (who has a Pascal-to- 386 compiler which may be helpful to me). Thanks indeed to Joe da Silva ;P.

Ciao!
