[LLVMdev] Balancing the registers

[Volkan Keleş]

Hi,

In our custom device, we keep the registers in two different places, one
for the odd-numbered registers and one for the even-numbered registers. To
fetch the data quickly, the registers in an instruction should be balanced.
For example, if an instruction contains 2 odd-numbered regs and 2
even-numbered regs, they can be fetched in one cycle.

Is it possible to enforce LLC to balance the registers as above?
