+       * sim-memopt.c (mmap_next_fd): New global.
+       (sim_memory_init): Reinitialize it.
+       (OPTION_MEMORY_MAPFILE, memory_option_handler): Support new
+       "--memory-mapfile FILE" option.  Check for some errors.
+       (do_memopt_add): Conditionally do mmap instead of malloc for
+       backing store of simulated memory.  Check for more errors.
+       (do_simopt_delete, sim_memory_uninstall): Corresponding cleanup.
+       * sim-memopt.h (munmap_length): New member of _sim_memopt.
+       * configure.in: Look for mmap/fstat related functions and headers.
+       * config.in, configure: Regenerated.
