[llvm-commits] [LLVM, SwitchInst, case ranges] Auxiliary patch #1

[Stepan Dyatkovskiy]

Hi, Chris.
I'm working on draft-experimental patch in this direction. Pair of 
ConstantArray + ConstantVector looking find. By now I have a question. I 
found that if I want to initialize array with zeroes it returns 
ConstantAggregateZero object. Is it possible to force creation of 
ConstantArray object? Or there is another approach and it is better to 
use ConstantAggregateZero (but how to do it for switch cases?)

Thanks!
