+ * HISTORY
+ * $Log:	asm.h,v $
+ * Revision 2.5  91/07/31  18:36:13  dbg
+ * 	Changes for STDC (from kernel version).
+ * 	[91/07/30  17:34:54  dbg]
+ * 
+ * Revision 2.4  91/05/14  17:56:49  mrt
+ * 	Correcting copyright
+ * 
+ * Revision 2.3  91/02/14  14:19:58  mrt
+ * 	Changed to new Mach copyright
+ * 	[91/02/13  12:15:20  mrt]
+ * 
+ * Revision 2.2  90/05/03  15:54:33  dbg
+ * 	Created.
+ * 	[90/04/30  15:39:58  dbg]
+ * 
+ * 	Typo on ENTRY if gprof
+ * 	[90/03/29            rvb]
+ * 	fix SVC for "ifdef wheeze" [kupfer]
+ * 	Fix the GPROF definitions.
+ * 	 ENTRY(x) gets profiled iffdef GPROF.
+ * 	 Entry(x) (and DATA(x)) is NEVER profiled.
+ * 	 MCOUNT can be used by asm that intends to build a frame,
+ * 	 after the frame is built.
+ * 	[90/02/26            rvb]
+ * 	Add #define addr16 .byte 0x67
+ * 	[90/02/09            rvb]
+ * 	Added LBi, SVC and ENTRY
+ * 	[89/11/10  09:51:33  rvb]
+ * 
+ * 	New a.out and coff compatible .s files.
+ * 	[89/10/16            rvb]
