/* Test for constraints on constant expressions. In C90 it is clear that certain constructs are not permitted in unevaluated parts of an expression (except in sizeof); in C99 it might fall within implementation latitude; and if the operands are suitable, diagnostics should not be issued. */ /* Origin: Joseph Myers <jsm28@cam.ac.uk>; inspired by http://deja.com/getdoc.xp?AN=524271595&fmt=text by Peter Seebach. */ /* { dg-do compile } */ /* { dg-options "-std=iso9899:1999 -pedantic-errors" } */ /* The comma operator is in a subexpression that is not evaluated, so OK by C99. In C90 a diagnostic is required since it is not in a sizeof. */ int i = (1 ? 0 : (2, 3));
