1997-04-18Ref gdb/11763 - can't stop a running simulator:Andrew Cagney2-0/+11
o Provide poll_quit callback to simulators so that they can poll for SIGINT on clueless OS's. o Add sim_stop to simulators so that clients can request a halt (eg gdbtk's STOP button) Works for PPC! o Re-arange remote-sim.c so that the hard work is moved from gdbsim_resume() to gdbsim_wait() (where it should be).

autoconf. * gencode.c (write_opcodes): Pad operands field to account for MSVC braindamage. * simops.c: Include errno.h. Exclude SYS_chown, since MSVC doesn't support it.

(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.
