allocno_hard_regs Struct Reference

Data Fields


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.
