====== Crosscompiler ======
The crosscompiler comprises three main steps which are platform independent as shown in the next figure. Further entries treat how arrays or interfaces are handled or how type checking is performed.

----
The backend of the compiler is platform specific. So far the register allocation and code generation is done for the PPC architecture, whereas the Linker32 is written for all 32 bit architectures. Work on the ARM architecture is in progress.
