--- Comment #5 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- Author: aoliva Date: Wed Feb 13 19:08:52 2019 New Revision: 268851 URL: https://gcc.gnu.org/viewcvs?rev=268851&root=gcc&view=rev Log: [PR86379] do not use TREE_TYPE for USING_DECL_SCOPE It's too risky to reuse the type field for USING_DECL_SCOPE. Language-independent parts of the compiler, such as location and non-lvalue wrappers, happily take the TREE_TYPE of a USING_DECL as if it was a type rather than an unrelated scope. For better or worse, USING_DECLs use the non-common struct so we can use the otherwise unused result field. Adjust fallout, from uses of TREE_TYPE that were supposed to be USING_DECL_SCOPE, to other accidental uses of TREE_TYPE of a USING_DECL. for gcc/cp/ChangeLog PR c++/86379 * cp-tree.h (USING_DECL_SCOPE): Use result rather than type. * name-lookup.c (strip_using_decl): Use USING_DECL_SCOPE. * search.c (protected_accessible_p): Follow USING_DECL_DECLS.
