-/// @class IRToDWARF IRToDWARF.h "lldb/Expression/IRToDWARF.h"
-/// @brief Transforms the IR for a function into a DWARF location expression
-///
-/// Once an expression has been parsed and converted to IR, it can run
-/// in two contexts: interpreted by LLDB as a DWARF location expression,
-/// or compiled by the JIT and inserted into the target process for
-/// execution.
-///
-/// IRToDWARF makes the first possible, by traversing the control flow
-/// graph and writing the code for each basic block out as location
-/// expression bytecode.  To ensure that the links between the basic blocks
-/// remain intact, it uses a relocator that records the location of every
-/// location expression instruction that has a relocatable operand, the
-/// target of that operand (as a basic block), and the mapping of each basic
-/// block to an actual location.  After all code has been written out, the
-/// relocator post-processes it and performs all necessary relocations.
