+ * break-catch-syscall.c (insert_catch_syscall)
+ (remove_catch_syscall): Adjust to pass reference to
+ inf_data->syscalls_counts directly via gdb::array_view.
+ * fbsd-nat.c (fbsd_set_syscall_catchpoint): Adjust to use bool
+ and gdb::array_view.
+ * linux-nat.c (linux_child_set_syscall_catchpoint): Likewise.

+ * target-debug.h (target_debug_print_bool): New.
+ (define target_debug_print_gdb_array_view_const_int): New.

+ * target.h (target_ops) <to_set_syscall_catchpoint>: Use
+ gdb::array_view and bool.
