Detailed Description

abstract description of needed or affected register bits.

due to special behaviour of this class when used in a set (RegisterSet) not all const functions have const character. use with caution.

@TODO For consitency width's should really be size_t

Constructor & Destructor Documentation

RegisterPart() [1/3]

etiss::RegisterPart::RegisterPart ( )

inline

Definition at line 78 of file CodePart.h.

RegisterPart() [2/3]

etiss::RegisterPart::RegisterPart ( const std::string &  name, unsigned  registerWidth, etiss::uintMax  bits = (uintMax)((intMax)-1)  )

inline

Parameters

name	register name should be same as defined by the respective etiss::CPUArch instance.
registerWidth	the register width in bits. must be consistet with the name and the context (e.g. cpu1 and cpu2 are allowed to have the same register with different widths).
bits	relevant bits of the register (->register part).
