+	* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): Expand parameter
+	SIZE to size_t.
+	(dwarf2_evaluate_loc_desc): Likewise.
+	(dwarf2_loc_desc_needs_frame): Likewise.
+	(locexpr_describe_location_1): Likewise.
+	* dwarf2loc.h (struct dwarf2_locexpr_baton): Make SIZE as
+	size_t.
+	(struct dwarf2_loclist_baton): Likewise.
+	* dwarf2read.c (struct dwarf_block): Likewise.
+	(dump_die_shallow): Use pulongest to print dwarf_block.size.
+	(decode_locdesc): Expand SIZE and I to size_t.
