764f1408a3 * mmap support for common simulators 
2001-03-16  Frank Ch. Eigler  <fche@redhat.com>

	Add support for mmap-based memory regions.
	* 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.
