/*
 *  Software MMU support
 *
 * Generate inline load/store functions for all MMU modes (typically
 * at least _user and _kernel) as well as _data versions, for all data
 * sizes.
 *
 * Used by target op helpers.
 *
 * MMU mode suffixes are defined in target cpu.h.
 */

/* XXX: find something cleaner.
 * Furthermore, this is false for 64 bits targets
