6bab69c65013be Rasmus Villemoes 2019-03-07 68 * Contrary to BUILD_BUG_ON(), static_assert() can be used at global
6bab69c65013be Rasmus Villemoes 2019-03-07 69 * scope, but requires the expression to be an integer constant
6bab69c65013be Rasmus Villemoes 2019-03-07 70 * expression (i.e., it is not enough that __builtin_constant_p() is
6bab69c65013be Rasmus Villemoes 2019-03-07 71 * true for expr).

6bab69c65013be Rasmus Villemoes 2019-03-07 73 * Also note that BUILD_BUG_ON() fails the build if the condition is

6bab69c65013be Rasmus Villemoes 2019-03-07 75 * false.

6bab69c65013be Rasmus Villemoes 2019-03-07 63 *
6bab69c65013be Rasmus Villemoes 2019-03-07 64 * static_assert() is a wrapper for the C11 _Static_assert, with a
6bab69c65013be Rasmus Villemoes 2019-03-07 65 * little macro magic to make the message optional (defaulting to the
6bab69c65013be Rasmus Villemoes 2019-03-07 66 * stringification of the tested expression).
6bab69c65013be Rasmus Villemoes 2019-03-07 67 *
6bab69c65013be Rasmus Villemoes 2019-03-07 68 * Contrary to BUILD_BUG_ON(), static_assert() can be used at global
6bab69c65013be Rasmus Villemoes 2019-03-07 69 * scope, but requires the expression to be an integer constant
6bab69c65013be Rasmus Villemoes 2019-03-07 70 * expression (i.e., it is not enough that __builtin_constant_p() is
6bab69c65013be Rasmus Villemoes 2019-03-07 71 * true for expr).
6bab69c65013be Rasmus Villemoes 2019-03-07 72 *
6bab69c65013be Rasmus Villemoes 2019-03-07 73 * Also note that BUILD_BUG_ON() fails the build if the condition is
6bab69c65013be Rasmus Villemoes 2019-03-07 74 * true, while static_assert() fails the build if the expression is
6bab69c65013be Rasmus Villemoes 2019-03-07 75 * false.
