From 92f93e54a36d424390b05a14df11d0d723e84f88 Mon Sep 17 00:00:00 2001 From: Jason Merrill Date: Thu, 19 Dec 2002 12:43:54 -0500 Subject: [PATCH] Handle anonymous unions at the tree level. C++ ABI change: Mangle anonymous unions using the name of their first named field (by depth-first search). Should not cause binary compatibility problems, though, as the compiler previously didn't emit anything for affected unions. * cp-tree.def (ALIAS_DECL): New tree code. * decl2.c (build_anon_union_vars): Build ALIAS_DECLs. Return the first field, not the largest. (finish_anon_union): Don't mess with RTL. Do set DECL_ASSEMBLER_NAME, push the decl, and write it out at namespace scope. * decl.c (lookup_name_real): See through an ALIAS_DECL. (pushdecl): Add namespace bindings for ALIAS_DECLs. * rtti.c (unemitted_tinfo_decl_p): Don't try to look at the name of a decl which doesn't have one. * typeck.c (build_class_member_access_expr): Don't recurse if we already have the type we want.
