* doc/invoke.texi (C++ Dialect Options): Note that
-fvisibility-inlines-hidden doesn't affect explicitly
instantiationed inline methods.
cp:
* decl2.c (determine_visibility_from_class): Don't use hidden
visibility for explicit instantiations.
testsuite:
* g++.dg/ext/visibility/fvisibility-inlines-hidden-3.C: New test.
