Swift 1.2 will include the @inline attribute, with never and __always as parameters. For more info, see here. As stated before, you rarely need to declare a function explicitly as @inline(__always) because Swift is fairly smart as to when to inline a function. Not having a function inlined, however, can be necessary in some code. … Read more
Is it possible to inline such a function, as I would do in C using macro or using inline keyword? No. Before reaching this specific instruction, Python interpreters don’t even know if there’s such a function, much less what it does. As noted in comments, PyPy will inline automatically (the above still holds – it … Read more
I guess you’re missing something, here. static function? Declaring a function static will make it “hidden” in its compilation unit. A name having namespace scope (3.3.6) has internal linkage if it is the name of — a variable, function or function template that is explicitly declared static; 3.5/3 – C++14 (n3797) When a name has … Read more
in K&R C or C89, inline was not part of the language. Many compilers implemented it as an extension, but there were no defined semantics regarding how it worked. GCC was among the first to implement inlining, and introduced the inline, static inline, and extern inline constructs; most pre-C99 compiler generally follow its lead. GNU89: … Read more
Let’s say you create a higher order function that takes a lambda of type () -> Unit (no parameters, no return value), and executes it like so: fun nonInlined(block: () -> Unit) { println(“before”) block() println(“after”) } In Java parlance, this will translate to something like this (simplified!): public void nonInlined(Function block) { System.out.println(“before”); block.invoke(); … Read more
Advantages By inlining your code where it is needed, your program will spend less time in the function call and return parts. It is supposed to make your code go faster, even as it goes larger (see below). Inlining trivial accessors could be an example of effective inlining. By marking it as inline, you can … Read more
