[LLVMdev] [LLVM] LoopUnswitch + SwitchInst

Hi all.

By now loops with switch instruction are unswitched value-by-value. For 
example for case range [0..9] we need to run unswitch process 10 times! 
I want try to optimize that case. Is there any hidden problems that 
blocks this improvement?

Regards,
Stepan.
