An aggregate length table is obtained by using the AGGREGATE option. The table includes structures but not arrays that have non-constant extents, but the sizes and offsets of elements within structures with non-constant extents may be inaccurate or specified as *. For the aggregates listed, the table contains the following information:
Please be careful when interpreting the data offsets indicated in the data length table. An odd offset does not necessarily represent a data element without halfword, fullword, or even double word alignment. If you specify or infer the aligned attribute for a structure or its elements, the proper alignment requirements are consistent with respect to other elements in the structure, even though the table does not indicate the proper alignment relative to the beginning of the table.
If there is padding between two structure elements, a /*PADDING*/ comment appears, with appropriate diagnostic information.
