As I noted over on android-ndk, function inlining and strength- reduction can turn "let's call an empty function 2 million times" into "let's set an integer to 2 million... oh, we don't use the result, so let's do nothing at all". "Hundreds of times slower" is easily achievable with specific constructs.
