[sdcc-devel] RE: Interested in porting SDCC

[Sandeep D. <sa...@dd...>]

Hi Tom

     1) It's my understanding that you encourage porting as long as the
     results are shared. Is this correct?

That is correct.

     3) What does AST mean/refer to? I know it has something to do with
     the evaluating expressions.

AST stands for Annotated Syntax Tree. The compiler breaks down the source
code into a tree form during parsing, then does some minimal optimizations &
syntax checking on this tree. It then generates an intermediated code to
perform the body of optimizations.

     4) What is the minimum set of files that would be involved in
     porting the compiler?

If you download the latest source files, you will see the target specific
files
have been moved to separate directories, essentially you will need to change
gen.c, ralloc.c.

     5) Is there any documentation other than SDCCUdoc.txt (93K). I'm
     looking for something that explains the internal program flow and
     data structures.

Afraid not , the code is the documentation, if you have any specific
questions
you can either email me, or send the question to the sdcc-devel list.
