 *
 * Functions for handling segments of code.
 *
 * $Log: codeinfo.h,v $
 * Revision 1.4  1996/07/17 16:01:09  grubba
 * Changed from {U,}{LONG,WORD,BYTE} to [SU]{8,16,32}.
 * Hopefully all places got patched.
 *
 * Revision 1.3  1996/07/13 19:32:23  grubba
 * Now defaults to very little debuginfo.
 * Added (un|set)patch().
 * Patches added to MakeLibrary(), MakeFunctions(), Abort() and AddLibrary().
 *
 * Revision 1.2  1996/07/01 19:16:40  grubba
 * Implemented ASL and ASR.
 * Changed semantics for new_codeinfo(), it doesn't allocate space for the code.
 * Added PeepHoleOptimize(). At the moment it just mallocs and copies the code.
 * Removed some warnings.
 *
 * Revision 1.1.1.1  1996/06/30 23:51:51  grubba
 * Entry into CVS
 *
 * Revision 1.4  1996/06/19 11:08:25  grubba
 * Some minor bugs fixed.
 *
 * Revision 1.3  1996/06/01 09:31:29  grubba
 *  Major changes.
 * Now generates output split into several files.
 * Now generates gasp assembler preprocessor output.
 * Now uses templates to build instructions.
 *
 * Revision 1.2  1996/05/11 17:23:27  grubba
 * parent pointer added to the code_info to simplify deletion, it's hard enough anyway.
 *
 * Revision 1.1  1996/05/08 07:24:22  grubba
 * Initial revision
