Well after polishing up my C++ skills I figured as a little side project I would work on this. I have already made a command-line interpreter that finds out what file to read from and what file to write to. I have also got a basic parser setup that finds all C functions in a given line I just need to setup how it compiles to assembly and dynamic memory allocation. Is there anything you guys would like to see in this?

Definitely.  This realm still needs lots of work seeing as few to none of the existing C z80 compilers have displaced the need for ASM programmers.

wow amazing, something like TIGCC (of course restricted to 83+ limitations) would rule the world of z80 calcs!

Yes thank you guys but I don't exactly know how TIGCC compiles and stuff but I will make this so that it compiles into Assembly code and then it will compile that code with TASM and Devpac83 so all you need to do is write the C code and compile.

NOTE: I don't know if I will be able to use typedef but also another note is that it will have inline assembly also so you can setup ASM routines to work with zC80. I am currently worknig on dynamic allocation with the 'int' function and once that is done making the rest should be easy riding :)smile.gif

I don't know if I will be able to include typedef and some other complicated C stuff like union and structure pointing :(sad.gif sorry

That woud be neat-o.

Time to polish my C++ skills... I think I lost them over the years...

TIGCC uses GCC as its base for compiling to 68k ASM and then creating binaries.

Most of the existing C compilers for z80 ASM will try to compile into an ASM file (not yet assembled) and then try to optimize the ASM code before creating working binaries.  This is a good idea because trying to use an 8-bit version of GCC (if one exists) probably wouldn't generate very optimized code.

At the very least, I think people would probably want to see basic if, else, while, for, switch/case, etc.  Things like malloc might not be worth the trouble since it's not very feasible on z80.  Most variable use in ASM is either static or for SMC use.  malloc is useable on 68k calcs because their AMS software already has a system to handle dynamic memory allocation.  the z80 calc OS do not afaik.

What I have learned:

This information comes straight from Kevin Kofler. You would only need to write a backend for the GCC compiler instead of a frontend. This is where z88dk failed by only trying to write a frontend for the GCC compiler. Also to compile the bins he has recommended using Binutils. I would want to use 'as' and then 'ld' or 'ld-tigcc'. Also I could port the libraries from TIGCC to z8-GCC with some work for the z80 calcs. Now I have a proposition.

Proposition:

I am looking for skilled C/C++ programmers that are willing to work on this porject with a group. TO keep this project clean, simple, and effcient there will be coding standards, a detailed dynamic list for bug reports and a todo list. This will help with interfacing with different programmers. Now I am only looking for a maximum of 9 programmers and a minimum of 3 programmers including me. If you want to tryout email me at [email protected]

you might want to talk to me on AIM at some point, I can help with this.

credentials:
    experience with 20 programming languages (including z80 asm and C)
    working knowledge of memory management, Context Free Grammars, and how compilers work.

JincS do you know how compilers work and about writing backends and binutils??

Som e. I'm working on a compiler/interpreter for a scripting language I'm developing. But I'm working on learning more.

Yes, you talked to Kevin Kofler like I suggested!  :)smile.gif

Also, remember my other suggestions at Psugen....

QUOTE

Use Flex for the lexer, Bison for the parser and GCC for the optimization and code generation. You don't have to "re-invent" the wheel. You should really talk to Kevin Kofler about this if you need any help; he's really good with this type of stuff (especially considering that he's the lead maintainer of TIGCC).

I'll be glad to help you.
