--- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #5) > Which of those 3, or all of them? At the end, I see changes in all of them - but I am not sure whether all of them in all lines. If I add a 'printf' to gcc/cgraph.h's symbol_table::register_symbol (which bumps 'order' alias symbol_order), the no-debug version has the following 11 additional symbols at some point; the first being: symbol_table::register_symbol: order=3774 name=static constexpr bool std::_PCC<<anonymous>, _T1, _T2>::_ConstructiblePair() [with _U1 = std::_Rb_tree_node_base*; _U2 = std::_Rb_tree_node_base*; bool <anonymous> = true; _T1 = std::_Rb_tree_node_base*; _T2 = std::_Rb_tree_node_base*] This one comes from gcc-trunk/include/c++/10.0.0/bits/stl_pair.h:100:29 and the backtrace is: #0 symtab_node::register_symbol (this=0x7fffeba9b168) at ../../gcc/symtab.c:379 #1 0x0000000000ba00e9 in cgraph_node::create(tree_node*) () at ../../gcc/cgraph.c:523 #2 0x0000000000b9ff11 in cgraph_node::get_create(tree_node*) () at ../../gcc/cgraph.c:545 #3 0x0000000000af6f51 in c_genericize(tree_node*) () at ../../gcc/c-family/c-gimplify.c:152 #4 0x0000000000916498 in cp_genericize(tree_node*) () at ../../gcc/cp/cp-gimplify.c:1809 #5 0x0000000000952312 in finish_function(bool) () at ../../gcc/cp/decl.c:16272 #6 0x0000000000a24cc4 in instantiate_decl(tree_node*, bool, bool) () at ../../gcc/cp/pt.c:24794 #7 0x00000000008f869d in instantiate_cx_fn_r(tree_node**, int*, void*) () at ../../gcc/cp/constexpr.c:5296 A bit later, I see lines for -g3 only, which come in addition for 'std::_Vector_base<std::vector<...'
