- * General EAX, EBX, ECX, EDX type registers.  Note that for
- * portability, and speed, the issue of byte swapping is not addressed
- * in the registers.  All registers are stored in the default format
- * available on the host machine.  The only critical issue is that the
- * registers should line up EXACTLY in the same manner as they do in
- * the 386.  That is:
- *
- * EAX & 0xff  === AL
- * EAX & 0xffff == AX
- *
- * etc.  The result is that alot of the calculations can then be
- * done using the native instruction set fully.

-Value of the default data segment
-
-REMARKS:
-Inline function that returns the default data segment for the current
-instruction.
-
-On the x86 processor, the default segment is not always DS if there is
-no segment override. Address modes such as -3[BP] or 10[BP+SI] all refer to
-addresses relative to SS (ie: on the stack). So, at the minimum, all
-decodings of addressing modes would have to set/clear a bit describing
-whether the access is relative to DS or SS.  That is the function of the
-cpu-state-varible M.x86.mode. There are several potential states:
-
-    repe prefix seen  (handled elsewhere)
-    repne prefix seen  (ditto)
-
-    cs segment override
-    ds segment override
-    es segment override
-    fs segment override
-    gs segment override
-    ss segment override
-
-    ds/ss select (in absense of override)
-
-Each of the above 7 items are handled with a bit in the mode field.

-*
-*  ========================================================================
-*
-* 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.

-*
-* 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 OF 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)

-* Description:  Program to validate the x86 emulator library for
-*               correctness. We run the emulator primitive operations
-*               functions against the real x86 CPU, and compare the result
-*               and flags to ensure correctness.
-*
-*               We use inline assembler to compile and build this program.
