* Description:  IBM HLL and pre-CV4 CodeView debugging information.
*
****************************************************************************/


/* Note: The following is conceptually similar to cv4.h, but significantly
 * different in detail. Why lump together old CodeView with IBM HLL instead
 * of keeping all CodeView information in one place? Firstly, the IBM HLL
 * format is an outgrowth of old CodeView style debug data, and therefore old
 * CodeView format is much closer to HLL than it is to CV4. Secondly, and more
 * importantly, it is possible to have HLL and old CodeView debug information
 * mixed in a single executable image, hence the need to support HLL and old
 * CodeView in a single package.
