Yes, I think all NoCCS are removed in the SCCfinal pass. NoCCS is a convenient thing to fill in when STG is initially created. Edward Excerpts from Ömer Sinan Ağacan's message of 2014-06-05 09:59:36 -0700:

Hi all,

Can a StgRhs have `NoCCS` as cost-centre stack when -prof is provided while compiling? Or is it always oneOf [CurrentCCS, DontCareCCS, SingletonCCS]?

I presume that since we have CCS constructor "DontCareCCS" and CCS field of StgRhs constructors are not `Maybe CostCentreStack` (so they're not optional), when -prof is provided CCS fields should not be filled with NoCCS(if we still don't care about CCS for some reason, it should be DontCareCCS) but I just wanted to make sure.

Thanks.
