--- Comment #1 from Michael Meissner <meissner at gcc dot gnu.org> ---
These functions have been documented since June 2018. The file extend.texi
contains:
The @code{__builtin_unpack_ibm128} function takes a @code{__ibm128}
argument and a compile time constant of 0 or 1. If the constant is 0,
the first @code{double} within the @code{__ibm128} is returned,
otherwise the second @code{double} is returned.
The @code{__builtin_pack_ibm128} function takes two @code{double}
arguments and returns a @code{__ibm128} value that combines the two
arguments.
