2019-03-07PR c++/88123 - lambda and using-directive.Jason Merrill7-2/+154
For named function calls in a template, the result of unqualified lookup is safed in CALL_EXPR_FN. But for operator expressions, no unqualified lookup is performed until we know whether the operands have class type. So when we see in a lambda a use of an operator that might be overloaded, we need to do that lookup then and save it away somewhere. One possibility would be in the expression, but we can't really add extra conditional operands to standard tree codes. I mostly implemented another approach using a new WITH_LOOKUP_EXPR code, but teaching everywhere how to handle a new tree code is always complicated. Then it occurred to me that we could associate the lookups with the function, which is both simpler and smaller. So this patch stores any operator bindings needed by a lambda function in an internal attribute on the lambda call operator. * name-lookup.c (op_unqualified_lookup) (maybe_save_operator_binding, discard_operator_bindings) (push_operator_bindings): New. * typeck.c (build_x_binary_op, build_x_unary_op): Call maybe_save_operator_binding. * decl.c (start_preparsed_function): Call push_operator_bindings. * tree.c (cp_free_lang_data): Call discard_operator_bindings.
