I simplified it to:

Consider all @code{static} functions called once for inlining into their
caller even if they are not marked @code{inline}.  If a call to a given
function is integrated, then the function is not output as assembler code
in its own right.

The "... in its own right" sounds weird to me, but I copied it from
inline-functions
description - it may be a valid idiom anyway(?)

Better?

Thanks,
Richard.
