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
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
the links to git repositories of all this).
