afaict they're not there. functions are just implicitly defined.

they are explicitly mentioned though (v3.1B):
section title: 7.6.2.2 VSX Instruction RTL Function Calls
and then it proceeds to define a bunch of functions, some in pseudo-code, some
partially english description, many calling other defined functions.

so, they have functions that they define and use lots of places, just they
never define what a function is or how to interpret one -- they probably assume
the reader has heard of function calls and returns before (which imo is a good
assumption, but being explicit is almost always better).

you want to do that?
