[PATCH] D43283: Variable register class using HwMode

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

What is the exact difference between DefaultRegClass and FP64RegClass?  TableGen precalculates certain properties of register classes that must be preserved, (such as class ordering).
