...ef) and a DIExpression to a DILocalVariable at a position in the instruction stream. That first SSA value argument is an implicit first element in the DIExpression. A more general form would be a more printf-like signature: llvm.dbg.value(DILocalVariable, DIExpression, ...) for example llvm.dbg.value_new(DILocalVariable("x"), DIExpression(DW_OP_LLVM_arg0), %x) llvm.dbg.value_new(DILocalVariable("y"), DIExpression(DW_OP_LLVM_arg0, DW_OP_LLVM_arg1, DW_OP_plus), %ptr, %ofs) llvm.dbg.value_new(DILocalVariable("z"), DIExpression(DW_OP_implicit_pointer, DW...

Hey folks, Would you all mind having a bit of a design discussion around the feature both at the DWARF level and the LLVM implementation? It seems like what's currently being proposed/reviewed (based on the DWARF feature as spec'd) is a pretty big change & I'm not sure I understand the motivation, exactly. The core point of my confusion: Why does describing the thing a pointer

...t pointer independently now, which is updated with many suggestions from this discussion?
