* eval.c (evaluate_subexp_for_address): Clarify error message.

Browse Source 
Use value_must_coerce_to_target.
	* infcall.c (value_arg_coerce): Call value_coerce_to_target.
	* valops.c (value_assign): Call value_coerce_to_target when
	assigning to anything but internalvars.  Leave GDB-side arrays
	as arrays when assigning to internalvars.
	(value_must_coerce_to_target, value_coerce_to_target): New.
	(value_coerce_array, value_addr): Call value_coerce_to_target.
	(value_array): Create the array in GDB's memory instead of
	the inferior's.
	* value.h (value_must_coerce_to_target, value_coerce_to_target):
	Declare.

	* gdb.texinfo (Expressions): Update description of malloced arrays.

	* gdb.base/printcmds.exp (test_print_array_constants): Do not expect
	*& to work on created array elements.
	(Top level): Test print $pc with a file.  Test string operations
	without a target.
	* gdb.base/ptype.exp: Do not expect *& to work on created array
	elements.
