--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I will fix this. I will declare VCE that change into non-full precision mode
types as non-moveable. movement_possibility_1 in LIM should get a similar
change even though I have not seen wrong code due to that yet; I suspect there
has not been a checker for undefinedness yet for that.
