allocno_hard_regs Struct Reference

Data Fields
HARD_REG_SET	set
int64_t	cost

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.
