I don't know enough about C++ machine code insertion, but the Ada
definitions can be found in section 13.8 in the Ada Reference Manual,
and the implementation specifics for GCC can be found in the GNAT
Reference Manual
(https://gcc.gnu.org/onlinedocs/gnat_rm/Machine-Code-Insertions.html#Machine-Code-Insertions).

That's a mistake.  Using "=>" is named notation.  Just listing values in
a comma-separated list is positional notation.
