* Decoding starts at the bottom of this file, in op1120() and op1145().
* Decoding starts near the bottom of this file, in op1120() and op1140(). Obviously, there are
* MANY more PDP-11 models than the 11/20 and 11/40, but for the broad model categories that PDPjs
* supports (ie, MODEL_1120, MODEL_1140, MODEL_1145, and MODEL_1170), the biggest differences are
* between MODEL_1120 and MODEL_1140, so decoding is divided into those two categories, and all
* other differences are handled inside the opcode handlers.
*
* The basic decoding approach is to dispatch on the top 4 bits of the opcode, and if further
* decoding is required, the dispatched function will dispatch on the next 4 bits, and so on
@ -51,6 +55,11 @@ var PDP11 = require("./defines");
* For example, opADD() passes the helper function fnADD() to the appropriate update method. This
* allows the update method to perform the entire read/modify/write operation, because the modify
* step is performed internally, via the fnXXX() helper function.
*
* For the handful of instructions in the 1140 tables that actually exist only on the 11/45 and
* 11/70 (ie, MFPD, MTPD, and SPL), those opcode handlers perform their own model checks. That's
* simpler than creating additional tables, and seems fine for instructions that are not commonly
* executed.
