I have a decently large set of objects (collected over rather a lot of
years) and I run each
libdwarf change through the 'latest' and 'changed' version of
libdwarf/dwarfdump and verify
that differences in the text output are appropriate (verify by looking
at them). Sometimes
looking at the differences is...pretty hard.
I (when at SGI some years ago) and others (recently) have provided examples
of problematic DWARF and some additional correctness tests in
libdwarf/dwarfdump.
I considered keeping 'correct' text of dwarfdump output for comparison,
but the size
was...overwhelming. So I run all tests twice, using (to the best of my
ability) all options.
Scripted, of course.
It is all in the source and the regression tests (see
reality.sgiweb.org/davea/dwarf.html and
the links to git repositories of all this).
