6 years agoMore underlining of bad arguments (PR c++/85110)
David Malcolm [Thu, 29 Mar 2018 14:43:01 +0000 (14:43 +0000)]
More underlining of bad arguments (PR c++/85110)

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)'

[PR c++/84789] adjust testcase for -fconcepts

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

linkage, which schedules them for deferred output, but we don't want
