2018-03-29More underlining of bad arguments (PR c++/85110)David Malcolm4-2/+190
As of r256448, the C++ frontend underlines many bad arguments in its diagnostics; those where perform_overload_resolution returns a non-NULL candidate, but there's a failure in convert_like_real. However, for the case where perform_overload_resolution fails, but there's a single non-viable candidate, the error is diagnosed by cp_build_function_call_vec, and that currently doesn't underline the bad argument: $ cat test.cc void callee (int one, const char **two, int three); void caller (const char *fmt) { callee (1, fmt, 3); } We emit: $ g++ test.cc test.cc: In function 'void caller(const char*)': test.cc:6:20: error: cannot convert 'const char*' to 'const char**' for argument '2' to 'void callee(int, const char**, int)' callee (1, fmt, 3); ^ It's going through convert_for_assignment, and implicitly using input_location. This patch updates convert_for_assignment for this case, using an EXPR_LOCATION if there is one, or falling back to input_location otherwise, underlining the argument in question: test.cc: In function 'void caller(const char*)': test.cc:6:14: error: cannot convert 'const char*' to 'const char**' for argument '2' to 'void callee(int, const char**, int)' callee (1, fmt, 3); ^~~ gcc/cp/ChangeLog: PR c++/85110 * typeck.c (convert_for_assignment): When complaining due to conversions for an argument, attempt to use the location of the argument. gcc/testsuite/ChangeLog: PR c++/85110 * g++.dg/diagnostic/param-type-mismatch-2.C: New test.

2018-03-28[PR c++/84789] adjust testcase for -fconceptsAlexandre Oliva2-1/+5
When compiling with -fconcepts, cp_parser_template_declaration_after_export calls cp_parser_template_introduction and that preparses qualified-ids not preceded by typename in such a way that, when we get to cp_parser_parse_and_diagnose_invalid_type_name and then cp_parser_diagnose_invalid_type_name, the nested name specifier no longer carries the previous template-dependent context, so we don't stand a chance to suggest the use of 'typename' any more.
