-* 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 (OP_DECODE).
-*
-* 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

-* modularize it, was basically: 1) no unnecessary subroutine calls,
-* 2) no routines more than about 200 lines in size, and 3) modularize

-* 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

+* Description:
+* 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 (OP_DECODE).
+*
+* 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
