Browse Source 
2008-06-30  Kenneth Zadeck <zadeck@naturalbridge.com>

	* df-scan.c (df_scan_free_ref_vec, df_scan_free_mws_vec): New
	macros.
       	(df_scan_free_internal): Free data structures not
	allocated in storage pools.
	(df_mw_hardreg_chain_delete_eq_uses): Use df_scan_free_mws_vec.
	(df_refs_add_to_chains): Use df_scan_free_ref_vec and 
	df_scan_free_mws_vec.
	* dse.c (dse_step6): Free offset_map_p and offset_map_n
	unconditionally.
