Fine for functions, but it's really not okay to use the same macros for data. Furthermore, we need to consider special entry points that don't behave like normal functions -- like system call or interrupt entry.
Why? Because if we're compiling with frame pointers, we would like the wrapper macros for functions to handle setting up and tearing down the frame pointer, at least in the common case.
