Most existing compilers are based on certain assumptions about the traget architecture. Re-targeting such a compiler to a target that does not satisfy those assumptions is impractical (too costly). This is the reason noone has yet re-targeted GCC to the (14 and 12 bit) PICs. Building a compiler from scratch is also a BIG project. So they might be right, although 'cannot' should be read as 'it is too expensive'. Wouter -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
