-* Language: ANSI C
-* Environment: Any
-* Developer: Kendall Bennett
-*
-* 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.

-* Language: ANSI C

-*
-* Description: This file contains the code to implement the primitive
-* machine operations used by the emulation code in ops.c
-*
-* Carry Chain Calculation
-*
-* This represents a somewhat expensive calculation which is
-* apparently required to emulate the setting of the OF343364 and AF flag.
-* The latter is not so important, but the former is. The overflow
-* flag is the XOR of the top two bits of the carry chain for an
-* addition (similar for subtraction). Since we do not want to
-* simulate the addition in a bitwise manner, we try to calculate the
-* carry chain given the two operands and the result.
-*
-* So, given the following table, which represents the addition of two
-* bits, we can derive a formula for the carry chain.
-*
-* a b cin r cout
-* 0 0 0 0 0
-* 0 0 1 1 0
-* 0 1 0 1 0
-* 0 1 1 0 1
-* 1 0 0 1 0
-* 1 0 1 0 1
-* 1 1 0 0 1
-* 1 1 1 1 1
-*
-* Construction of table for cout:
-*
-* ab
-* r \ 00 01 11 10
-* |------------------
-* 0 | 0 1 1 1
-* 1 | 0 0 1 0
-*
-* By inspection, one gets: cc = ab + r'(a + b)
-*
-* That represents alot of operations, but NO CHOICE....
-*
-* Borrow Chain Calculation.
-*
-* The following table represents the subtraction of two bits, from
-* which we can derive a formula for the borrow chain.
-*
-* a b bin r bout
-* 0 0 0 0 0
-* 0 0 1 1 1
-* 0 1 0 1 1
-* 0 1 1 0 1
-* 1 0 0 1 0
-* 1 0 1 0 0
-* 1 1 0 0 0
-* 1 1 1 1 1
-*
-* Construction of table for cout:
-*
-* ab
-* r \ 00 01 11 10
-* |------------------
-* 0 | 0 1 0 0
-* 1 | 1 1 1 0
-*
-* By inspection, one gets: bc = a'b + r(a' + b)
