From be4d1333163c056f725fbbb96b400ce3d22802a7 Mon Sep 17 00:00:00 2001 From: Michael Snyder Date: Wed, 9 Jan 2002 00:37:02 +0000 Subject: 2002-01-03 Michael Snyder Implement a "generate-core-file" command in gdb, save target state. * gcore.c: New file. Implement new command 'generate-core-file'. Save a corefile image of the current state of the inferior. * linux-proc.c: Add linux-specific code for saving corefiles. * target.h (struct target_ops): Add new target vectors for saving corefiles; to_find_memory_regions and to_make_corefile_notes. (target_find_memory_regions): New macro. (target_make_corefile_notes): New macro. * target.c (update_current_target): Inherit new target methods. (dummy_find_memory_regions): New place-holder method. (dummy_make_corefile_notes): New place-holder method. (init_dummy_target): Initialize new dummy target vectors. * exec.c (exec_set_find_memory_regions): New function. Allow the exec_ops vector for memory regions to be taken over. (exec_make_note_section): New function, target vector method. * defs.h (exec_set_find_memory_regions): Export prototype. * procfs.c (proc_find_memory_regions): New function, corefile method. (procfs_make_note_section): New function, corefile method. (init_procfs_ops): Set new target vector pointers. (find_memory_regions_callback): New function. (procfs_do_thread_registers): New function. (procfs_corefile_thread_callback): New function. * sol-thread.c (sol_find_memory_regions): New function. (sol_make_note_section): New function. (init_sol_thread_ops): Initialize new target vectors. * inftarg.c (inftarg_set_find_memory_regions): New function. Allow to_find_memory_regions vector to be taken over. (inftarg_set_make_corefile_notes): New function. Allow to_make_corefile_notes vector to be taken over. * thread-db.c (thread_db_new_objfile): Don't activate thread-db interface layer if not target_has_execution (may be a corefile). * config/i386/linux.mh: Add gcore.o to NATDEPFILES. * config/sparc/sun4sol2.mh: Ditto. * config/alpha/alpha-linux.mh: Ditto. * config/arm/linux.mh: Ditto. * config/i386/x86-64linux.mh: Ditto. * config/ia64/linux.mh: Ditto. * config/m68k/linux.mh: Ditto. * config/mips/linux.mh: Ditto. * config/powerpc/linux.mh: Ditto. * config/sparc/linux.mh: Ditto. --- gdb/inftarg.c | 21 ++++++++++++++++++++- 1 file changed, 20 insertions(+), 1 deletion(-) (limited to 'gdb/inftarg.c') diff --git a/gdb/inftarg.c b/gdb/inftarg.c index 6b37030..9035310 100644 --- a/gdb/inftarg.c +++ b/gdb/inftarg.c @@ -1,5 +1,6 @@ /* Target-vector operations for controlling Unix child processes, for GDB. - Copyright 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000 + Copyright 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1998, 1999, + 2000, 2002 Free Software Foundation, Inc.
