--- Comment #2 from Mike Frysinger <vapier at gentoo dot org> ---
the code in question is:
:function:::void:do_dmfc1b:int rt, int fs
*mipsIV:
*mipsV:
*mips64:
*mips64r2:
*mips64r6:
*vr4100:
*vr5000:
*r3900:
*micromips64:
{
  if (SizeFGR () =3D=3D 64)
    GPR[rt] =3D FGR[fs];
  else if ((fs & 0x1) =3D=3D 0)
    GPR[rt] =3D SET64HI (FGR[fs+1]) | FGR[fs];
  else
    GPR[rt] =3D SET64HI (0xDEADC0DE) | 0xBAD0BAD0;
  TRACE_ALU_RESULT (GPR[rt]);
}

this was introduced here:
