--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed.  While we support -fcf-protection=3Dbranch and -fcf-protection=
=3Dreturn,
-fcf-protection=3Dbranch,return gives an error:

xgcc: error: unknown Control-Flow Protection Level =E2=80=98branch,return=
=E2=80=99
xgcc: note: valid arguments to =E2=80=98-fcf-protection=3D=E2=80=99 are: br=
anch check full none
retur=
