+ * Expands to the GNU C `noinline` function attribute if the compiler is gcc.
+ * If the compiler is not gcc, this macro expands to nothing.
+ *
+ * Declaring a function as `noinline` prevents the function from being
+ * considered for inlining.
+ *
+ * The attribute may be placed before the declaration, right before the
+ * `static` keyword.
