2002-01-03 Michael Snyder <msnyder@redhat.com> 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.
