I think the following (while not news) needs to be said simply and directly.
It is impossible to obey all the DWARF5 rules on file numbering in the line table at the same time. They contradict each other, taking the standard as a whole. [this consistency issue is solely DWARF5]. A simple solution is to say that the file number value 0 meaning of 'no file' is eliminated so that part of Section 2.14 page 50 is invalidated. So then we have a zero-based file array along with all references to it. And declare that the 'file' line table register defaults to zero (DWARF5 Table 6.4 Page 153). Then the standard is self-consistent. (Clang has been using this approach for some time now). I created a document documenting all the places in the standard involving line table file numbering but this emaill is already long enough.
