...played 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 patch D70385, I have included test points to display that multi layered pointers...

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:
