Re: [musl] dynlink.c tests

Sorry for the late reply Rich.

That's what my current plan of attack is but I was wondering if the
musl codebase itself has such a test suite already
(something similar to the libc test suite)

How do dynlink authors validate they haven't broken any edge cases in
program loading?
(i.e. such as DT_GNU_HASH etc..)
