/* Test warnings and errors for incomplete parameter types. Should not be warned for in declarations that are not definitions: bug 17881. Void types may be a special case, especially for unnamed parameters and when qualified or with a storage class specifier; see C90 6.5.4.3, DR#017 Q14, C90 TC1, DR#157, C99 J.2 (referencing C99 6.7.5.3); the precise rules are unclear. */ /* Origin: Joseph Myers <jsm@polyomino.org.uk> */ /* { dg-do compile } */ /* { dg-options "" } */ struct s; void f (struct s); void (*g)(struct s); struct t { void (*p)(struct s); }; struct s { int b; }; void h (struct s x) { } void j(struct t2); /* { dg-warning "'struct t2' declared inside parameter list" } */ union u; void v(union u x) { } /* { dg-error "parameter 1 \\('x'\\) has incomplete type" } */ void p(void x); /* { dg-warning "parameter 1 \\('x'\\) has void type" } */ void q(const void x); /* { dg-warning "parameter 1 \\('x'\\) has void type" } */
