Currently, two patches undergoing review wish to add a new operator for LLVM's DIExpression: D70642[0], and D82363[1]. Though both of these cases use the same name, the operators have different meanings: in the former, it has the form `DW_OP_LLVM_argN` where N is in [0-7], and represents the Nth argument of the containing intrinsic; its purpose is to enable the intrinsic @llvm.dbg.derefval, which...

...new Dwarf expression DW_OP_explicit_pointer as de-referenced value can be displayed explicitly (in place). In LLVM IR, we represent it using dbg.derefval and DW_OP_LLVM_explicit_pointer operation. Both of these two branches have some common implementation to define new operations (Dwarf and IR). (D70642, D70643, D69999, D69886). First branch has additional patches (D70260, 70384, D70385, D70419). Second branch has additional patch ( D70833). Let me try to comment on points raised by you. - Branch 2, (patch D70833) handles cases when temporaries (not existing variables) are optimized out. - In pat...

Hi folks, I am pushing a PoC patch https://reviews.llvm.org/D70833 for review which includes the case when temporary is promoted. For such cases it generates IR as call void @llvm.dbg.derefval(metadata i32 3, metadata !25, metadata !DIExpression(DW_OP_LLVM_explicit_pointer, DW_OP_LLVM_arg0)), !dbg !32 And llvm-darfdump output looks like ------------- 0x0000007b:
