[PATCH] D133637: Bug fix on stable hash calculation for machine operands RegisterMask and RegisterLiveOut

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

An alternative approach if we cannot guarantee the availabily of a MachineFunction reference, may be to change machine operands to store `ArrayRef<Register> RegMask` instead of `uint32_t RegMask`. It shouldn't affect memory usage because MachineOperand size is determined by the biggest union member anyway which is already 2 pointers...
