// PR c++/91364 - Implement P0388R4: Permit conversions to arrays of unknown bound. // { dg-do run { target c++2a } } // Ranking of reference initialization conversions int f(int(&)[]) { return 1; } // (1) int f(int(&)[1]) { return 2; } // (2) int h(int(*)[]) { return 1; } // (a) int h(int(*)[1]) { return 2; } // (b) // From P0388R4: // (2) and (b) should clearly be better than (1) and (a), respectively, // as the former overloads are more restricted. // (a) should be worse than (b), which is implied by (a) necessitating // a qualification conversion in that case. int main () { int arr[1]; if (f(arr) != 2) __builtin_abort (); if (h(&arr) != 2) __builtin_abort (); }
