This commit implements functions for identifying and extracting extended ptrace event information from a Linux wait status. These are just convenience functions intended to hide the ">> 16" used to extract the event from the wait status word, replacing the hard-coded shift with a more descriptive function call. This is preparatory work for implementation of follow-fork and detach-on-fork for extended-remote linux targets. gdb/ChangeLog: * linux-nat.c (linux_handle_extended_wait): Call linux_ptrace_get_extended_event. (wait_lwp): Call linux_is_extended_waitstatus. (linux_nat_filter_event): Call linux_ptrace_get_extended_event and linux_is_extended_waitstatus. * nat/linux-ptrace.c (linux_test_for_tracefork): Call linux_ptrace_get_extended_event. (linux_ptrace_get_extended_event): New function. (linux_is_extended_waitstatus): New function. * nat/linux-ptrace.h (linux_ptrace_get_extended_event) (linux_is_extended_waitstatus): New declarations. gdb/gdbserver/ChangeLog: * linux-low.c (handle_extended_wait): Call linux_ptrace_get_extended_event. (get_stop_pc, get_detach_signal, linux_low_filter_event): Call linux_is_extended_waitstatus. --- |
