* 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.
