pub struct VReg { /* private fields */ }
Expand description
A virtual register. Contains a virtual register number and a class.
A virtual register (“vreg”) corresponds to an SSA value for SSA input, or just a register when we allow for non-SSA input. All dataflow in the input program is specified via flow through a virtual register; even uses of specially-constrained locations, such as fixed physical registers, are done by using vregs, because we need the vreg’s live range in order to track the use of that location.
