-*
-* Description:  This file includes subroutines to implement the decoding
-*               and emulation of all the x86 processor instructions.
-*
-* There are approximately 250 subroutines in here, which correspond
-* to the 256 byte-"opcodes" found on the 8086.  The table which
-* dispatches this is found in the files optab.[ch].
-*
-* Each opcode proc has a comment preceeding it which gives it's table
-* address.  Several opcodes are missing (undefined) in the table.
-*
-* Each proc includes information for decoding (DECODE_PRINTF and
-* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc
-* functions (START_OF_INSTR, END_OF_INSTR).
-*
-* Many of the procedures are *VERY* similar in coding.  This has
-* allowed for a very large amount of code to be generated in a fairly
-* short amount of time (i.e. cut, paste, and modify).  The result is
-* that much of the code below could have been folded into subroutines
-* for a large reduction in size of this file.  The downside would be
-* that there would be a penalty in execution speed.  The file could
-* also have been *MUCH* larger by inlining certain functions which
-* were called.  This could have resulted even faster execution.  The
-* prime directive I used to decide whether to inline the code or to
-* modularize it, was basically: 1) no unnecessary subroutine calls,
-* 2) no routines more than about 200 lines in size, and 3) modularize
-* any code that I might not get right the first time.  The fetch_*
-* subroutines fall into the latter category.  The The decode_* fall
-* into the second category.  The coding of the "switch(mod){ .... }"
-* in many of the subroutines below falls into the first category.
-* Especially, the coding of {add,and,or,sub,...}_{byte,word}
-* subroutines are an especially glaring case of the third guideline.
-* Since so much of the code is cloned from other modules (compare
-* opcode #00 to opcode #01), making the basic operations subroutine
-* calls is especially important; otherwise mistakes in coding an
-* "add" would represent a nightmare in maintenance.
