Insert a runtime check only for arrays with a non-constant size. (build_new): Detect and diagnose negative array sizes. gcc/testsuite/ * init/new45.C: New test to verify that operator new is invoked with or without overhead for a cookie. * init/new44.C: New test for placement new expressions for arrays with excessive number of elements. * init/new43.C: New test for placement new expressions for arrays with negative number of elements. * other/new-size-type.C: Expect array new expression with an excessive number of elements to be rejected.
