Use keep_going in proceed and start_step_over too
The main motivation of this patch is sharing more code between the proceed (starting the inferior for the first time) and keep_going (restarting the inferior after handling an event) paths and using the step_over_chain queue now embedded in the thread_info object for pending in-line step-overs too (instead of just for displaced stepping). So this commit: - splits out a new keep_going_pass_signal function out of keep_going that is just like keep_going except for the bits that clear the signal to pass if the signal is set to "handle nopass". - makes proceed use keep_going too. - Makes start_step_over use keep_going_pass_signal instead of lower level displaced stepping things. One user visible change: if inserting breakpoints while trying to proceed fails, we now get: (gdb) si Warning: Could not insert hardware watchpoint 7. Could not insert hardware breakpoints: You may have requested too many hardware breakpoints/watchpoints. Command aborted. (gdb) while before we only saw warnings with no indication that the command was cancelled: (gdb) si Warning: Could not insert hardware watchpoint 7. Could not insert hardware breakpoints: You may have requested too many hardware breakpoints/watchpoints. (gdb) Tested on x86_64-linux-gnu, ppc64-linux-gnu and s390-linux-gnu. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * gdbthread.h (struct thread_info) <prev_pc>: Extend comment. * infrun.c (struct execution_control_state): Move higher up in the file. (reset_ecs): New function. (start_step_over): Now returns int. Rewrite to use keep_going_pass_signal instead of manually starting a displaced step. (resume): Don't call set_running here. If displaced stepping can't start now, clear trap_expected. (find_thread_needs_step_over): Delete function. (proceed): Set up finish_thread_state_cleanup. Call set_running. If the current thread needs a step over, push it in the step-over chain. Don't set insert breakpoints nor call resume directly here. Instead rewrite to use start_step_over and keep_going_pass_signal. (finish_step_over): New function. (handle_signal_stop): Call finish_step_over instead of start_step_over. (switch_back_to_stepped_thread): If the event thread needs another step-over do that first. Use start_step_over. (keep_going_pass_signal): New function, factored out from ... (keep_going): ... here. (_initialize_infrun): Comment moved here. * thread.c (set_running_thread): New function. (set_running, finish_thread_state): Use set_running_thread.
