Detailed Description

Memory abstration for TranslatorZ3. Memory elements are only accessed,
never written. To give a concrete value for a given memory cell in a solver,
add "mem32.get(address, size) == <value>" constraints to your equation.
The endianness of memory accesses is handled accordingly to the "endianness"
attribute.

Note: Will have one memory space for each addressing size used.
For example, if memory is accessed via 32 bits values and 16 bits values,
these access will not occur in the same address space.

Constructor & Destructor Documentation

def miasm2.ir.translators.z3_ir.Z3Mem.__init__	(		self,
			endianness = "<",
			name = "mem"
	)

Initializes a Z3Mem object with a given @name and @endianness.
@endianness: Endianness of memory representation. '<' for little endian,
    '>' for big endian.
@name: name of memory Arrays generated. They will be named
    name+str(address size) (for example mem32, mem16...).
