Jeff Johnston <jjohnstn@redhat.com> * breakpoint.c (watchpoints_triggered): New. (bpstat_stop_status): Remove STOPPED_BY_WATCHPOINT argument. Check watchpoint_triggered instead. Combine handling for software and hardware watchpoints. Do not use target_stopped_data_address here. Always check a watchpoint if its scope breakpoint triggers. Do not stop for thread or overlay events. Improve check for triggered watchpoints without a value change. (watch_command_1): Insert the scope breakpoint first. Link the scope breakpoint to the watchpoint. * breakpoint.h (enum watchpoint_triggered): New. (struct breakpoint): Add watchpoint_triggered. (bpstat_stop_status): Update prototype. (watchpoints_triggered): Declare. * infrun.c (enum infwait_status): Add infwait_step_watch_state. (stepped_after_stopped_by_watchpoint): Delete. (handle_inferior_event): Make stepped_after_stopped_by_watchpoint local. Handle infwait_step_watch_state. Update calls to bpstat_stop_status. Use watchpoints_triggered to check watchpoints. * remote.c (stepped_after_stopped_by_watchpoint): Remove extern. (remote_stopped_data_address): Do not check it. * gdb.texinfo (Setting Watchpoints): Adjust warning text about multi-threaded watchpoints. * gdbint.texinfo (Watchpoints): Describe how watchpoints are checked. Describe sticky notification. Expand description of steppable and continuable watchpoints. (Watchpoints and Threads): New subsection. * gdb.threads/watchthreads.c (thread_function): Sleep between iterations. * gdb.threads/watchthreads.exp: Allow two watchpoints to trigger at once for S/390. Generate matching fails and passes.
