2018-09-19syscall_emul: expand AuxVector classBrandon Potter
The AuxVector class is responsible for holding Process data. The data that it holds is normally setup by an OS kernel in the process address space. The purpose behind doing this is to pass in information that the process will need for various reasons. (Check out the enum in the header file for an idea of what the AuxVector holds.) The AuxVector struct was changed into a class and encapsulation methods were added to protect access to the member variables. The host ISA may have a different endianness than the simulated ISA. Since data is passed between the process address space and the simulator for auxiliary vectors, we need to worry about maintaining endianness for the right context.

2016-11-09syscall_emul: [patch 8/22] refactor process classBrandon Potter
Moves aux_vector into its own .hh and .cc files just to get it out of the already crowded Process files. Arguably, it could stay there, but it's probably better just to move it and give it files. The changeset looks ugly around the Process header file, but the goal here is to move methods and members around so that they're not defined randomly throughout the entire header file. I expect this is likely one of the reasons why I several unused variables related to this class. So, the methods are declared first followed by members. I've tried to aggregate them together so that similar entries reside near one another. There are other changes coming to this code so this is by no means the final product.
