gdb/gdb-6.3-large-core-20051206.patch

2005-12-14  Jeff Johnston  <jjohnstn@redhat.com>

	* symfile-mem.c (read_memory): New static read callback function.
	(symfile_add_from_memory): Pass read_memory to bfd instead of
	target_read_memory.
	* target.c (target_xfer_memory): Add support for LONGEST len and
	change all callers.
	(deprecated_debug_xfer_memory, target_read_memory): Ditto.
	(target_write_memory, do_xfer_memory): Ditto.
	(target_xfer_memory_partial, target_read_memory_partial): Ditto.
	(target_write_memory_partial): Ditto.
	* infptrace.c (child_xfer_memory): Ditto.
	* linux-nat.c (linux_nat_xfer_memory): Ditto.
	(linux_nat_proc_xfer_memory): Ditto.
	* dcache.c (dcache_xfer_memory): Ditto.
	* exec.c (xfer_memory): Ditto.
	* remote.c (remote_xfer_memory): Ditto.
	* remote-sim.c (gdbsim_xfer_interior_memory): Ditto.
	* target.h: Change prototypes for functions changed above.
	* linux-nat.h: Ditto.
	* remote.h: Ditto.
	* dcache.h: Ditto.

2007-10-15  Jan Kratochvil  <jan.kratochvil@redhat.com>

	Port to GDB-6.7.
