* Input param :
|
|
* out : The file pointer that we write to (the output file to intel asm)
|
|
* cpu_buffer : The memory buffer we have our binary code that we whant convert
|
|
* cpu_pos : Current positions in the cpu_buffer
|
|
* cpu_size : The memory size of the cpu_buffer
|
|
* BaseAddress : The base address you whant the binay file should run from
|
|
* cpuarch : if it exists diffent cpu from a manufactor like pentium,
|
|
* pentinum-mmx so on, use this flag to specify which type
|
|
* of cpu you whant or do not use it if it does not exists
|
|
* other or any sub model.
|
|
*
|
|
* Return value :
|
|
* value -1 : unimplement
|
|
* value 0 : wrong opcode or not vaild opcode
|
|
* value +1 and higher : who many byte we should add to cpu_pos
