Sure it can. It just can't use the hardware floating point instructions. It
can still do software floating point with ints.
It also can't do
union { int i; void * x; }
Hard to emulate pointer indirection with integer math.
Again, a compiler limitation at most- you can use self-modifying code to
accomplish this.
It's really hard to put self-modifying code in ROM.
Well, you program a robot to remove the rom chip and replace it. Easy :)
Alright, you got me on that one. I can't see a way to do function pointers when you have no indirect jumps and no way to modify the original code.
Why do you have to modify the original code?
How about a trampoline? Place a jump instruction into RAM and always
jump there and then it jumps to where you want to go.
Also, is PC not modifiable? Normally there is a "Put into PC register".
