From: Pedro Alves Date: Wed, 12 Mar 2014 11:21:36 +0000 (+0000) Subject: Make the nto-procfs.c target inherit inf-child.c. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ee8e9165af41505e5b33397afdbe5c424d5aa52c;p=binutils-gdb.git Make the nto-procfs.c target inherit inf-child.c. So that all native targets inherit a single "superclass". Target methods that are set to or do the same as inf-child.c's are removed. Not tested. gdb/ 2014-03-12 Pedro Alves * nto-procfs.c: Include inf-child.h. (procfs_ops): Delete global. (procfs_can_run): Delete method. (procfs_detach, procfs_mourn_inferior): Unpush the passed in target pointer instead of referencing procfs_ops. (procfs_prepare_to_store): Delete. (init_procfs_ops): Delete function. (procfs_target): New function, based on init_procfs_ops, but inherit inf_child_target. (_initialize_procfs): Use procfs_target. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 265489c4905..abfbfd780de 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,16 @@ +2014-03-12 Pedro Alves + + * nto-procfs.c: Include inf-child.h. + (procfs_ops): Delete global. + (procfs_can_run): Delete method. + (procfs_detach, procfs_mourn_inferior): Unpush the passed in + target pointer instead of referencing procfs_ops. + (procfs_prepare_to_store): Delete. + (init_procfs_ops): Delete function. + (procfs_target): New function, based on init_procfs_ops, but + inherit inf_child_target. + (_initialize_procfs): Use procfs_target. + 2014-03-12 Pedro Alves * windows-nat.c: Include inf-child.h. diff --git a/gdb/nto-procfs.c b/gdb/nto-procfs.c index bdda7ce251a..c552a8eb1f1 100644 --- a/gdb/nto-procfs.c +++ b/gdb/nto-procfs.c @@ -42,13 +42,12 @@ #include "command.h" #include "regcache.h" #include "solib.h" +#include "inf-child.h" #define NULL_PID 0 #define _DEBUG_FLAG_TRACE (_DEBUG_FLAG_TRACE_EXEC|_DEBUG_FLAG_TRACE_RD|\ _DEBUG_FLAG_TRACE_WR|_DEBUG_FLAG_TRACE_MODIFY) -static struct target_ops procfs_ops; - int ctl_fd; static void (*ofunc) (); @@ -57,10 +56,6 @@ static procfs_run run; static void procfs_open (char *, int); -static int procfs_can_run (struct target_ops *self); - -static void init_procfs_ops (void); - static ptid_t do_attach (ptid_t ptid); static int procfs_can_use_hw_breakpoint (struct target_ops *self, @@ -602,14 +597,6 @@ procfs_files_info (struct target_ops *ignore) target_pid_to_str (inferior_ptid), nto_procfs_path); } -/* Mark our target-struct as eligible for stray "run" and "attach" - commands. */ -static int -procfs_can_run (struct target_ops *self) -{ - return 1; -} - /* Attach to process PID, then initialize for debugging it. */ static void procfs_attach (struct target_ops *ops, char *args, int from_tty) @@ -917,7 +904,7 @@ procfs_detach (struct target_ops *ops, const char *args, int from_tty) inferior_ptid = null_ptid; detach_inferior (pid); init_thread_list (); - unpush_target (&procfs_ops); /* Pop out of handling an inferior. */ + unpush_target (ops); /* Pop out of handling an inferior. */ } static int @@ -1036,7 +1023,7 @@ procfs_mourn_inferior (struct target_ops *ops) } inferior_ptid = null_ptid; init_thread_list (); - unpush_target (&procfs_ops); + unpush_target (ops); generic_mourn_inferior (); } @@ -1240,13 +1227,6 @@ procfs_kill_inferior (struct target_ops *ops) target_mourn_inferior (); } -/* Store register REGNO, or all registers if REGNO == -1, from the contents - of REGISTERS. */ -static void -procfs_prepare_to_store (struct target_ops *self, struct regcache *regcache) -{ -} - /* Fill buf with regset and return devctl cmd to do the setting.
