1311 and put_word.
1312
1313 * interp.c: OP should be an array of 32bit operands!

1320 insns. Invert 's' bit if 'ov' bit is set for some
1321 instructions. Fix 'cy' bit handling for numerous
1322 instructions. Make the simulator stop when a halt
1323 instruction is encountered. Very crude support for
1324 emulated syscalls (trap 0).
1325 * v850_sim.h: Include "callback.h" and declare
1326 v850_callback. Items in the operand array are 32bits.

1404 (do_formats_9_10): Rough cut so shift ops will work.
1405 (sim_resume): Tweak to deal with format 1 and format 2
1406 handling in a single funtion. Don't update the PC
