Detailed Description

Generic MeP-c4 instruction

Notes:
    - this object is used to build internal miasm instructions based
      on mnemonics
    - it must be implemented !

Member Function Documentation

__str__()

def miasm.arch.mep.arch.instruction_mep.__str__

(

self

)

Return the mnemonic as a string.

Note:
    - it is not mandatory as the instruction class already implement
      it. It used to get rid of the padding between the opcode and the
      arguments.
    - most of this code is copied from miasm/core/cpu.py

Reimplemented from miasm.core.cpu.instruction.

arg2str()

def miasm.arch.mep.arch.instruction_mep.arg2str (   expr,   pos = None,   loc_db = None  )

static

Convert mnemonics arguments into readable strings according to the
MeP-c4 architecture manual and their internal types

Notes:
    - it must be implemented ! However, a simple 'return str(expr)'
      could do the trick.
    - it is used to mimic objdump output

Args:
    expr: argument as a miasm expression
    pos: position index in the arguments list

Here is the caller graph for this function:

breakflow()

def miasm.arch.mep.arch.instruction_mep.breakflow

(

self

)

Instructions that stop a basic block.

dstflow()

def miasm.arch.mep.arch.instruction_mep.dstflow

(

self

)

Instructions that explicitly provide the destination.

dstflow2label()

def miasm.arch.mep.arch.instruction_mep.dstflow2label	(		self,
			loc_db
	)

Set the label for the current destination.

   Note: it is used at disassembly

Here is the call graph for this function:

fixDstOffset()

def miasm.arch.mep.arch.instruction_mep.fixDstOffset

(

self

)

Fix/correct the instruction immediate according to the current offset

   Note: - it is used at assembly
         - code inspired by miasm/arch/mips32/arch.py

Here is the call graph for this function:

get_dst_num()

def miasm.arch.mep.arch.instruction_mep.get_dst_num

(

self

)

Get the index of the argument that points to the instruction destination.

Here is the caller graph for this function:

getdstflow()

def miasm.arch.mep.arch.instruction_mep.getdstflow	(		self,
			loc_db
	)

Get the argument that points to the instruction destination.

Here is the call graph for this function:

Here is the caller graph for this function:

is_subcall()

def miasm.arch.mep.arch.instruction_mep.is_subcall

(

self

)

Instructions used to call sub functions.

Here is the caller graph for this function:

splitflow()

def miasm.arch.mep.arch.instruction_mep.splitflow

(

self

)

Instructions that splits a basic block, i.e. the CPU can go somewhere else.
