What is necessary to add a new compiler?

[Zingam]

Perhaps it has been asked before but I'm asking here again:

Is it difficult to add a new compiler support? How much knowledge about C::B API and internals is needed?

I have in mind the port of GCC and GDB for the TI MSP430 family. http://mspgcc.sourceforge.net/

Look at the following wiki articles. Search for "Installing xxx Compiler"
where xxx is all sorts of compiler names.

Also, Google produces many pertinent results:
