When creating Dwarf tests I did it at all levels: IR checking for
metadata, ELF checking for Dwarf and GDB execution checking for
correct behaviour.

All that as LIT driven, so a "make check" would give me the results in
a few seconds, with the benefit of a good dev iteration, as David
mentioned.

Unfortunately, none of that was in the open, so I can't share... :(

Since GDB already has a good and standard test infrastructure, it'd
likely get a good chunk of bad Dwarf our of the way before you start
worrying about Lauterbach's specifics.

Do you have a good (maybe open) Dwarf validation suite available?
There is no such thing as too many tests... ;)
