  • Convert all the RBM_REG* to regMaskTP
  • Introduce SRBM_REG* that can be used at places where we just need SingleTypeRegSet
  • Start using regMaskTP for registers at kill RefPosition

I tried doing that, but as a cascade effect I need to make genSingleTypeRegSet, getRegForType(), etc. as constexpr which I am not sure is worth doing for just an assert. Will pass this on for now.

predicate registers starts from 64 thru 80 and the mask of them start with 0x0. I can make it work, but just want to rely on the mask that we already have in register files and how we use them currently.

I tried doing that, but as a cascade effect I need to make genSingleTypeRegSet, getRegForType(), etc. as constexpr which I am not sure is worth doing for just an assert. Will pass this on for now.

predicate registers starts from 64 thru 80 and the mask of them start with 0x0. I can make it work, but just want to rely on the mask that we already have in register files and how we use them currently.
