The reason for the change was to force the ; CA bit to be set--and remain set--once code accesses the coprocessor. ; ; Future operating systems will use the Coprocessor Active (CA) bit in ; the Old Processor Status Register to determine whether or not to save ; coprocessor state, etc.. This means that the instruction control field ; Set Coprocessor Active (SA) bit should be used as follows: ; ; (1) any coprocessor STORE must have its SA bit set to 1, ; so as to set CA, ; ; and (2) any coprocessor LOAD must have its SA bit set to 0, ; so as to prevent clearing CA. ;------------------------------------------------------------------------ ; Date: 89/01/30 12:32:13; author: jim; lines added/del: 5/4 ; Corrected CP_IEEE_GRADUAL_UFLOW_MODE and CP_RMS_MASK. ; Added CP_EXCPS_POSITION, the ls bit of the CP_XXX_EXCP ensemble. ; fixed a few typos in comments. ;------------------------------------------------------------------------ ; Date: 89/01/23 18:00:26; author: jim; lines added/del: 488/468 ; Richard O. Parker ; January 5, 1989 ; ; 1) The _cp_prec_field in the "cp_build_inst", "cp_build_inst_h" ; and "cp_build_inst_l" macros was not being defined in the case ; of Am29K-supported floating-point instructions (e.g., FADD, FSUB, ; DADD, etc.). ; ; 2) The multiplexor select codes in the opcode table entries ; associated with the "cp_build_inst", "cp_build_inst_h" and ; "cp_build_inst_l" macros, pertaining to the CONVERT_F_TO_D ; and CONVERT_D_TO_F instructions were incorrect. ;------------------------------------------------------------------------ ; Date: 88/12/20 14:28:26; author: jim; lines added/del: 1/1 ; Larry Westerman corrected definition of CP_MOVE_P. ;
