backend. When compiling with a normal C compiler, these functions are
implemented by a library implemented in C.

+Figure \ref{CompilingMontiumC} shows the flow for compiling a MontiumC program
into a Montium binary file, which can be loaded directly onto a Montium. The
process is roughly divided into two parts (each of which corresponds to a
different program in the compiler suite): The frontend and the backend.
The frontend takes in a MontiumC program and turns it into a lower level

-section). The frontend is responsible for mapping higher level
-C constructs onto simpler instructions, for canonicalizing and simplifying the
-code. These canonicalizations and simplifications ensure that the backend can be

The backend, in turn, takes in this reduced description of the program and
transforms this into a valid Montium binary. To do this, it must find an ALU
