Subject: c++/modules: avoid too many hidden friends in ADL
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=52a24bcecd388ab6e7d4e6500809fc761f6e7ca5;p=thirdparty%2Fgcc.git

c++/modules: avoid too many hidden friends in ADL

Most of the add_fns calls in adl_namespace_fns also call ovl_skip_hidden,
but we were forgetting that in the case of imports, which meant that for
24_iterators/const_iterator/112490.cc we were considering the
unreachable_sentinel_t hidden friend operator== and therefore failing.

gcc/cp/ChangeLog:

	* name-lookup.cc (name_lookup::adl_namespace_fns): Also skip hidden
	in the module case.
