libiberty/ PR debug/49408 * cp-demangle.c (d_print_comp): Suppress argument list for function references by the '&' unary operator. Keep also already processed variant without the argument list. Suppress argument list types for function call used in an expression. * testsuite/demangle-expected: Fix excessive argument list types in `test for typed function in decltype'. New testcase for no argument list types printed. 3 new testcases for function references by the '&' unary operator..
