The Pharo VM (a version of the Cog VM) optimizes execution by mapping
contexts to stack frames and lazily instantiating contexts.
It further jits/compiles methods used more than once to machine-code and implements a number of send optimization schemes in that machine-code.
Note that we use only use with a special label for building:
The names of these labels is essential as we rely on them to extract the generated VM in downstream builds.
To run this build, be sure to install the following packages on your system: zip, unzip, tar, wget, cmake, gcc You should also run: yum groupinstall "Development tools"
