-// This file provides the interface to the LiveDebugVariables analysis.
-//
-// The analysis removes DBG_VALUE instructions for virtual registers and tracks
-// live user variables in a data structure that can be updated during register
-// allocation.
-//
-// After register allocation new DBG_VALUE instructions are emitted to reflect
-// the new locations of user variables.
