Comment:
Replying to [comment:20 akio]:
> I implemented a support for ELF weak symbols on Linux. The
implementation follows hgolden's design above, except that it doesn't
support undefined weak symbols. The change is implemented in 3 patches:
the first one simplifies the code, the second one implements the support,
and the third one adds a special symbol !__dso_handle. This is not
directly related to weak symbols, but is required to load C++ object
files.
akio, it's great that you have done this, since I let it lie fallow. I
have reassigned the ownership to you. You should also generate a test for
your patch so it can be merged into the HEAD branch.
