No, because -g writes the necessary debug info markers for
llvm-dwarfdump to produce its report. Without -g, llvm-dwarfdump
prints nothing when executed.

I can remove -g from the first one, however, the .rel_debug_line
contents are slightly different without it, but it does pick the
discriminator information.
