ChangeLog:

* printcmd.c (print_scalar_formatted): Always truncate
	unsigned data types.

	* cli-dump.c (struct callback_data): Change type of load_offset
	to CORE_ADDR.
	(restore_binary_file): Update type casts.
	(restore_command): Parse load_offset as address, not long.

	* utils.c (string_to_core_addr): Do not sign-extend value.
	* varobj.c (find_frame_addr_in_frame_chain): Truncate frame_base
	before comparing against requested frame address.

testsuite/ChangeLog:

	* gdb.base/dump.exp: Handle SPU like 64-bit platforms.
