	* config/tc-alpha.c (add_to_link_pool): Remove basesym parameter.
	Locally declare basesym.  Add comments.  Do not set literal_pool_size.
	(load_expression): Adjust call to add_to_link_pool.
	(s_alpha_pdesc): Define pdesc symbol using dot.
	Do not set literal_pool_size.
	(s_alpha_end): Use NULL instead of 0.
