 * HISTORY
 * $Log: asm.h,v $
 * Revision 1.2  2000/03/07 06:10:59  wsanchez
 * Make main branch like boot-3, which builds.
 *
 * Revision 1.1.2.1  2000/02/29 00:04:34  jliu
 * Added legacy header files.
 *
 * Revision 1.1.1.1  1997/09/30 02:45:05  wsanchez
 * Import of kernel from umeshv/kernel
 *
 * Revision 2.1.1.6  90/03/29  20:45:08  rvb
 * 	Typo on ENTRY if gprof
 * 	[90/03/29            rvb]
 * 
 * Revision 2.1.1.5  90/02/28  15:47:31  rvb
 * 	fix SVC for "ifdef wheeze" [kupfer]
 * 
 * Revision 2.1.1.4  90/02/27  08:47:30  rvb
 * 	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]
 * 
 * Revision 2.1.1.3  90/02/09  17:23:23  rvb
 * 	Add #define addr16 .byte 0x67
 * 	[90/02/09            rvb]
 * 
 * Revision 2.1.1.2  89/11/10  09:51:33  rvb
 * 	Added LBi, SVC and ENTRY
 * 
 * Revision 2.1.1.1  89/10/22  11:29:38  rvb
 * 	New a.out and coff compatible .s files.
 * 	[89/10/16            rvb]
