[LLVMdev] Register Allocation

[Christian Scheuer]

Hi,

I'm currently working on a register allocation problem. Therefore, I 
want to reduce the number of available registers of the ARM by a large 
amount to see the impact on the assembly code. I tried to change the 
number via the ARMRegisterInfo.td by stripping the registerClasses (like 
it is described in the Code generator docs), but the resulting code is 
unchanged.
Is there an easy alternative using the registerscavening.cpp directly or 
did I miss out something?
