Method Details [hide private]

__init__(self)
(Constructor)

source code 

Hand in a register definition which consists of a list of (<name>, <width>) tuples.

Overrides: memory.IMemory.__init__

_emu_getGpReg(self, reg, tsize)

source code 

Automagically map all general purpose register accesses to their tsize equiv. Helps clean up a lot of code (and makes a nice place for AMD64 to hook ;) )

_emu_setGpReg(self, reg, val, tsize)

source code 

Automagically map all general purpose register accesses to their tsize equiv. Helps clean up a lot of code (and makes a nice place for AMD64 to hook ;) )

executeOpcode(self, op)

source code 

This is the core method for the

Overrides: Emulator.executeOpcode
(inherited documentation)

getSegmentIndex(self, op)

source code 

The *default* segmentation is none (most arch's will over-ride). This method may be implemented to return a segment index based on either emulator state or properties of the particular instruction in question.

Overrides: Emulator.getSegmentIndex
(inherited documentation)

i_cmpsd(self, op)

source code 

Compare the dword pointed at by ds:esi to ds:edi. (if equal, update esi/edi by one acording to DF)

integerSubtraction(self, op)

source code 

Do the core of integer subtraction but only *return* the resulting value rather than assigning it. (allows cmp and sub to use the same code)

readMemValue(self, addr, size)

source code 
Overrides: memory.IMemory.readMemValue

twoRegCompound(self, topreg, botreg, size)

source code 

Build a compound value where the value of the top reg is shifted and or'd with the value of the bot reg ( assuming they are size bytes in length). The return is size * 2 wide (and unsigned).
