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. -* -****************************************************************************/ - -#include "x86emu/x86emui.h" - -/*----------------------------- Implementation ----------------------------*/ - -/**************************************************************************** -PARAMETERS: -op1 - Instruction op code - -REMARKS: -Handles illegal opcodes. -****************************************************************************/ -static void x86emuOp_illegal_op( - u8 op1) -{ - START_OF_INSTR(); - if (M.x86.R_SP != 0) { - DECODE_PRINTF("ILLEGAL X86 OPCODE\n"); - TRACE_REGS(); - DB( printk("%04x:%04x: %02X ILLEGAL X86 OPCODE!\n", - M.x86.R_CS, M.x86.R_IP-1,op1)); - HALT_SYS(); - } - else { - /* If we get here, it means the stack pointer is back to zero - * so we are just returning from an emulator service call - * so therte is no need to display an error message.

+*
+* 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.
