I meant dropping the inline specifier, not going back to manual
inlining. As a general rule, you don't need to add the 'inline'
specifier unless your function is defined in a header. In all other
cases the compiler is able to inline things on its own when it sees the
number of instructions is small enough or when the function is only
called once.
