--- Comment #4 from Christophe Lyon <clyon at gcc dot gnu.org> ---
Maybe, that's what I'm trying to figure out.

Given the comment in arm.h before the definition of CANNOT_CHANGE_MODE_CLASS,
maybe we need to define more patterns, for all the sizes where
CANNOT_CHANGE_MODE_CLASS is true on big-endian?
