* 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.
