ARM and TMS320c67x are also supported to some extend.

TinyCC is an "exercice of style" and I have no plan to improve it, 
except for small bug fixes. However, some of its ideas could be used to 
optimize the GCC parser. It is not acceptable that GCC is so slow at 
compiling code.

Another point is that there is no way to easily improve the TinyCC code 
generator - it is a "dead end" and I knew it from the start.

It would be educationnal to start a new project from TinyCC to 
incorporate a simple IR representation, to allocate registers with 
linear scan or graph coloring and then to generate code from it. The 
resulting compilation speed would not be necessarily slower, the TinyCC 
executable size would not be bigger and the code quality would be much 
closer to GCC. But it requires a lot of work and I no longer have the 
time nor the motivation to do it !
