[RFC] [DebugInfo] Using DW_OP_entry_value within LLVM IR
...ing the functionality (especially in “optimized” code by turning “<optimized_out>” values into real values). The call site information includes info about call itself (described with DW_TAG_call_site) with corresponding children representing function arguments at the call site (described with DW_TAG_call_site_params). The most interesting DWARF attribute for us (here) is DW_AT_call_value which contains a DWARF expression which represents a value of the parameter at the time of the call. For the context of this RFC, more relevant part of the feature is the callee side, and it refers to new DWARF operation - DW_...
