Detailed Description

The structure contains information about hard registers can be assigned to allocnos. Usually it is allocno profitable hard registers but in some cases this set can be a bit different. Major reason of the difference is a requirement to use hard register sets that form a tree or a forest (set of trees), i.e. hard register set of a node should contain hard register sets of its subnodes.
