C compiler

Brag time once more, this code: http://pastebin.com/ryZttMW2 produces the attached result.

Looks great! Seems like a pretty complex test too. :]

[zoranc]

The very first pre-pre alpha version (V0.004) is here for your viewing pleasure. There are many things missing (take a look at the TODO.txt) and most likely there are many bugs too. I believe there are no viruses inside, but to be sure please check it yourself.

Enjoy!

Very nice, Zoranc!
This will probably lower the threshold for people to starting deving on PM.

[zoranc]

I hope so, Agilo, I hope so. Such a nice device deserves bigger audience.

Thanks to Lupin we got now div/mod and slightly improved mul routines. One Item from the TO-DO list is removed.

As before no guaranties, hope you like it... etc. etc. Ver. 0.006 of the vbccpm C compiler freshly baked and served.

really nice progress... First thing on my personal wishlist is interrupt support and support for linking (vasm and vlink) to have external function libraries.

[zoranc]

inline assembly supported now. look at the demo inside for an example how to do it.

interrupts should be rather easy i'd be able to do it in a few hours, but now i'm dead tired.

vasm/vlink that's another story any volunteers for that one?

@lupin: i hope you are motivated enough to finish my carts, thought soldering and testing is probably less fun than writing libraries in C.

[zoranc]

fixed bug in the inline assembler handling. now frame pointer is unwinded by the compiler.

[zoranc]

added interrupt support with a small demo how to use it.

Hey zoranc,

Code: Select all

// Comment does not work
/* Comment does work */

Will you add // comments?

Code: Select all

*((char *)(0x2029)) = 0x01;

compiles to:

Code: Select all

	mov	a,1
	mov	hl,8233
	mov	8233,a

... interesting, isn't it?
