<pre>To be able to reproduce the results of an experiment, it is important to know
which flags were used during a simulation.
Some driver flags can significant impact the entire simulation. For example,
flag -noalias changes how loads / stores dependencies are perceived by the
simulator.
It is not always possible to infer which flags were used during a simulation.
So, ideally, it would be nice if we could store them into a special section of
the JSON file.
Example of flags which can affect the simulation are:
-lqueue , -squeue , -mcpu, -mtriple, -march, -noalias.
For simplicity, we could simply just store the sequence of string arguments
passed in input to llvm-mca.</pre>
