<p>It requires .loc directive with fileref, line number and column
number. Seems to me, line number and column number can be zeroed.</p>
<p>The function starting label is used to evaluate function
relocation info and without this .loc directive the relocation
info is incorrect. I can't say why it requires this directive for
the initial label. All other labels inherit their location from
the first following instruction, but not the very first one. <br>

nvcc always emits debug location before the very first label
that represents function start. So, we can consider this as
the requirement for NVPTX.<br>

<div>Any debug location? Just a file location? Something else?</div>

<div>If you take a look at a normal ELF file it actually has
implications on how the line table both works and is
encoded. It becomes a more global location.</div>
