1314 (sim_stop_reason): Gross hacks to get c-torture running.
1315 * simops.c: Simplify code for computing targets of bCC
1316 insns. Invert 's' bit if 'ov' bit is set for some
1317 instructions. Fix 'cy' bit handling for numerous
1318 instructions. Make the simulator stop when a halt
1319 instruction is encountered. Very crude support for
1320 emulated syscalls (trap 0).
1321 * v850_sim.h: Include "callback.h" and declare
1322 v850_callback. Items in the operand array are 32bits.

1325
1326 * interp.c (sim_resume): Fix code to check for a format 3
1327 opcode.

1398 (do_format_6): Get operands correctly and call the target
1399 function.
1400 (do_formats_9_10): Rough cut so shift ops will work.
1401 (sim_resume): Tweak to deal with format 1 and format 2
1402 handling in a single funtion. Don't update the PC
1403 for format 3 insns. Fix typos.
1404 * simops.c: Slightly reorganize. Add condition code handling
1405 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1406 and "not" instructions.
1407 * v850_sim.h (reg_t): Registers are 32bits.
