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. ; .equ ERROR,0 .equ NO_ERROR,1 .equ DOUBLE_FUNCTION,0 .equ SINGLE_FUNCTION,1 .equ T_OPERATION,0 .equ Q_OPERATION,1 .equ R_SOURCE_29000,0 .equ R_SOURCE_29027,1 .equ S_SOURCE_29000,0 .equ S_SOURCE_29027,1 .equ DESTINATION_29000, 0 .equ DESTINATION_29027, 1 ;
