[RFC] [DebugInfo] Using DW_OP_entry_value within LLVM IR
...data describing the debug value to support/refer to entry value/backup value as well (and when primary location is lost, the value with DW_OP_entry_value becomes the primary one). One way could be extending of llvm.dbg.value with an additional operand as following:
llvm.dbg.value(…, DIEntryValExpression(DW_OP_uconst, 5)) // DIEntryValExpression implicitly contains DW_OP_entry_value operation
The bottom line is that the production of call-site side of the feature stays the same, but LLVM will have more freedom to generate more of DW_OP_entry_values operation on the callee side.
Any thoughts on...
