9fca2fd3c6 * gencode.c: Fix various indention & style problems.
Remove test code.  Remove #if 0 code.
        * interp.c: Provide prototypes for all static functions.
        Fix minor indention problems.
        (sim_open, sim_resume): Remove unused variables.
        (sim_read): Return type is "int".
        * simops.c: Remove unused variables.
        (divh): Make result of divide-by-zero zero.
        (setf): Initialize result to keep compiler quiet.
        (sar instructions): These just clear the overflow bit.
        * v850_sim.h: Provide prototypes for put_byte, put_half
        and put_word.
Cleaning up.

d81352b8b8 * interp.c: OP should be an array of 32bit operands!
(v850_callback): Declare.
        (do_format_5): Fix extraction of OP[0].
        (sim_size): Remove debugging printf.
        (sim_set_callbacks): Do something useful.
        (sim_stop_reason): Gross hacks to get c-torture running.
        * simops.c: Simplify code for computing targets of bCC
        insns.   Invert 's' bit if 'ov' bit is set for some
        instructions.  Fix 'cy' bit handling for numerous
        instructions.  Make the simulator stop when a halt
        instruction is encountered.  Very crude support for
        emulated syscalls (trap 0).
        * v850_sim.h: Include "callback.h" and declare
        v850_callback.  Items in the operand array are 32bits.
Fixes & syscall stuff.

Stu Grossman
4fa14cf71c * gencode.c (process_instructions): Generate word64 and uword64
instead of `long long' and `unsigned long long' data types.
	* interp.c:  #include sysdep.h to get signals, and define default
	for SIGBUS.
	* (Convert):  Work around for Visual-C++ compiler bug with type
	conversion.
	* support.h:  Make things compile under Visual-C++ by using
	__int64 instead of `long long'.  Change many refs to long long
	into word64/uword64 typedefs.

	windows out to the stack just before returning to GDB.  Makes
