For the PL/I front-end project (pl1gcc.sourceforge.net), I am just about to begin to add a preprocessor expansion step, and was wondering what other front-end do.
My initial thoughts were to create a completely separate program that just do the preprocessing and passes the output to the compiler. Some background info regarding the PL/I preprocessor. The PL/I processor language is more of a real text pre-processor that anything else, eg it is possible to define functions and have declared variables of data type either numeric or character based, and control statements includes for-loops, if-then constructs and goto statements. any thoughts, hints is much appreciated.
