[Tinycc-devel] [Noob] Mac, Mach-O/ELF, compiling only to memory

[Marcel Weiher]

Hi folks,

I discovered tcc a while ago and really like the idea and the  
implementation, so I've been working at getting it to work on Mac OS X.

So far, I've managed to

- compile it (mostly register definitions that needed tweaking)
- get it it to run (some linker alignment flags needed to be set  
differently)
- and produce some ELF object files

So not very much, but it's a start.  In order to side-step the ELF/ 
Mach-O issue for now, I've tried just jitting some code, but that  
appears to want to load some (ELF) libraries and thus fails, so I  
haven't yet been able to run some code produced by tcc.  Is there a  
way to jit code into memory without external libraries?  I can provide  
function pointers it may want.

I've also looked at what it would take to add Mach-O support, but the  
structure of the code isn't very clear to me, especially since I am  
not particularly familiar with ELF.  Any suggestions?

Thanks!

Marcel
