Porting gcc

[Mile Davidovic]

Hi everybody

I have questions regarding support new MIPS based processor, MDE950xx. In the 
basic it is same as R3000 but except one thing, this processor does not support 
lwl and lwr instructions, what is best way to support this "feature"?

We want to use latest gcc version, 3.4. What is necessary steps for porting gcc? 
If we have success to support what is best way to add patches to gcc?

Best regards Mile
