Is anyone testing for a (cross-) target (board) with dynlinking?

Thanks to all.  I no longer think there's anything that needs
fixing in the gcc testsuite regarding copying of libraries or in
particular libgcc_s.so.1; I just need my baseboard-file to copy
over every *.so* from ld_library_path or make them otherwise
accessible.  It seems dejagnu deliberately leaves this to the
target, as it's not done for any other library either, and
ld_library_path is the blessed variable (no, not in the dejagnu
*documentation*; just used in the dejagnu sources with the same
use as in gcc. ;)

You mean a -rpath followed by -rpath-link (the latter overriding
for the link)?  That might do it.

That might be interpreted as "NFS setups are slower" so to
disambiguate: people have reported NFS setups being
significantly faster (than copy-based protocols).  There's
reason: you wouldn't have to copy the whole program over for
each test, instead letting Linux page it in.  Copying just the
*libraries* would probably help of course.
