Lines Matching full:constant

254  * This returns a constant expression while determining if an argument is
255  * a constant expression, most importantly without evaluating the argument.
259  * - sizeof() return an integer constant expression, and does not evaluate
261  * - The results of comparing two integer constant expressions is also
262  *   an integer constant expression.
268  * - The C Standard defines "null pointer constant", "(void *)0", as
270  * - If (x) is an integer constant expression, then the "* 0l" resolves
271  *   it into an integer constant expression of value 0. Since it is cast to
272  *   "void *", this makes the second operand a null pointer constant.
273  * - If (x) is not an integer constant expression, then the second operand
274  *   resolves to a void pointer (but not a null pointer constant: the value
275  *   is not an integer constant 0).
282  *   - When one operand is a null pointer constant (i.e. when x is an integer
283  *     constant expression) and the other is an object pointer (i.e. our
289  *     constant expression) and the other is an object pointer (i.e. our
294  *     sizeof(int) == sizeof(int)     (x) was a constant expression
295  *     sizeof(int) != sizeof(void)    (x) was not a constant expression
310  * Note that the condition may involve non-constant values,
317  * Similar to statically_true() but produces a constant expression
320  * which require their input to be a constant expression and for which
