;    Version information :
;
;        Version 1.0 - 1 June 1988   - Larry Westerman (smart_macros.h)
; 
; Revision 1.4  89/02/01  18:26:03  jimh
; Changed to relect the new symbols from Bob Perlman, and the new include file.s
; 
; Revision 1.3  89/01/31  10:13:34  jimh
; Updated to use symbols from Bob Perlmans fpsymbol.h file.  This is
; an extensive change.
; 
; Revision 1.2  89/01/26  09:23:50  jimh
; This version checked in previous to substituting Bob Perlman's floating
; point symbols.
; 
; Revision 1.1  89/01/24  13:23:29  jim
; Initial revision
; Replaces smart_macros.h ver 1.11.
; 
; 
; 
;
;  NOTES:
;
;    This package makes the following assumptions about the use of these
;    smart macros:
;
;      1.  These macros will be after the entry code for a transcendental
;          routine.  This entry code will move the original function arguments
;          (by value, if the target language is FORTRAN) into the global
;          registers t0/t1 and t2/t3 (t0 and t2 for single precision
;          routines).
;      2.  The sources of all operands will be one register from the
;          following list:
;            t0 or  t2  - the source is one of the original input operands
;            rtn0       - the source is rtn0, which should be used as the
;                         source for all constant values to be sent to the
;                         AM29027 (when used)
;            FP0 - FP7  - the source is one of the fp registers
;      3.  The destination of all operations will be a register from the
;          following list:
;            rtn0       - the destination is the function return value
;            FP0 - FP7  - the destination is one of the fp registers
;      4.  The additional registers available for temporary use are
;          t4, lrp, and slp.  
;
;    These register definitions are all taken from the file "proregs.a"
;    which was supplied by AMD.  NOTE that the FP0-FP7 registers, for the
;    Am29000 version of the file, overlap with the rtn0-rtn15 registers, so
;    that FP0 corresponds to rtn0/rtn1, FP1 to rtn2/rtn3, and so forth.
