DWARF not being generated for local variable, though MD looks right(?)

[...]

To follow up after some debugging and more digging, it turns out that I hadn't created a DILexicalBlock for my function and then the variables were getting silently dropped; I had assumed that the DISubprogram would be enough and that the DILexicalBlock was only necessary for inner scopes. With that, it all works swimmingly so far.
