c05d17211e * interp.c (CHECKHILO): Don't set HIACCESS, LOACCESS, or HLPC.
It's OK to have a mult follow a mult.  What's not OK is to have a
	mult follow an mfhi.

* run.c (main): Explicitly cast malloc() parameter.

This is needed because for certain builds the size field being given
to malloc() is actually 64bits long, and without a cast or malloc
prototype the resulting value used by malloc() depended on the host
endianness, and how long long paramaters are passed into 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.
