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.

* (profile_print_pc): Write header out in target byte order.

* sim-profile.c (profile_pc_init): Correct bug in loop logic when
adjusting the pc shift value.

* aclocal.m4 (SIM_AC_OPTION_SCACHE): Properly
handle the case where a numeric value is supplied.

* configure: Regenerated with sim_scache fix.
* sim-fpu.h (sim_fpu_printn_fpu): Declare.
* sim-fpu.c (print_bits): Add digits parameter. Print only as many
trailing digits as specified (-1 to print all digits).
(sim_fpu_print_fpu): New wrapper around sim_fpu_printn_fpu.
(sim_fpu_printn_fpu): Rename from sim_fpu_print_fpu; update calls
to print_bits ().
* sim-endian.h: Don't have parameters on macro definitions which
are simply renaming functions, to permit use of XCONCAT2 in both
the macro name and the arguments in a use of such a definition.
In sim/ppc:
* sim-endian.h: Don't have parameters on macro definitions which
are simply renaming functions, to permit use of XCONCAT2 in both
the macro name and the arguments in a use of such a definition.
* cgen.sh: Handle an isa argument between cpu and mach. Default to
`all'. Pass `-i' options to cgen applications.
* Make-common.in (cgen-arch, cgen-cpu, cgen-decode, cgen-cpu-decode,
cgen-desc): Pass $(isa) to cgen.sh.
* sim-events.c (sim_events_remain_time): New function returning
the time that remains before the event is raised.
* hw-events.c (hw_event_remain_time): Likewise.
* sim-events.h (sim_events_remain_time): Declare.
* hw-events.h (hw_event_remain_time): Declare.
* sim-hw.c: Use <errno.h> instead of <sys/errno.h>
(OPTION_HW_LIST): New option --hw-list to list the devices.
(hw_option_handler): List the device tree with 'sim_hw_print'.
* sim-bits.h (_MSB_16, _LSB_16): Define for 16-bit targets.
(MASK, LSBIT, MSBIT): Likewise and use _MSB_16 and _LSB_16.
(EXTENDED): Define for 16-bit word size.
* sim-bits.c (LSEXTRACTED, MSEXTRACTED, LSINSERTED,
MSINSERTED, LSSEXT, MSSEXT): Implement for 16-bit word size.
* sim-types.h: Added support for 16-bit targets.
* cgen-fpu.h: Rename extsfdf to fextsfdf. Rename truncdfsf to
ftruncdfsf.
* cgen-accfp.c (fextsfdf): New function.
(ftruncdfsf): New function.
(cgen_init_accurate_fpu): Initialize fextsfdf and ftruncdfsf.
