[LLVMdev] Question about register allocators

[Vikram S. Adve]

What is the status of RegAllocLocal, RegAllocBigBlock and  
RegAllocSimple allocators?  I am considering using one of them as a  
basis for a course project on register allocation in my class.  In  
particular, are those allocators in regular use and/or have they been  
tested recently?  I am particularly interested in the code as of  
version 4.0 but if anything has improved since then, the current code  
would be useful too.

Also, any suggestions for simple but useful projects are welcome.

Thanks,
