Corinna Vinschen 5623fbd4ca * devices.in: Raise number of handled serial ports to 64.
* devices.cc: Regenerate.
2006-10-09 08:27:23 +00:00
Christopher Faylor 67483cb2cd * dcrt0.cc (do_exit): Rely on sigproc_terminate to set exit_state
appropriately.
* pinfo.cc (pinfo::exit): Always call sigproc_terminate here.  Rely on
sigproc_terminate to signal signal thread to handle eventual process exit.
* sigproc.cc (no_signals_available): Change criteria for determining if this
process can handle signals to itself.
(my_sendsig): New variable.  Copy of my sendsig handle.
(proc_can_be_signalled): Don't send signals if exit code is set.
(sigproc_terminate): Use and set exit_state appropriately to determine when to
do anything.  Send __SIGEXIT to self to control process exit.
(sig_send): Use my_sendsig for sending signals.  Don't call
proc_can_be_signalled for myself since the criteria is now different for
sending signals to myself.
(wait_sig): Copy myself->sendsig to my_sendsig for future use.  Exit signal
loop when __SIGEXIT is received.  Wait for main thread to exit and use its exit
status to actually exit process.
