This work is in line with the recently started Modelica 4 design effort which includes moving implementation of language features from the compiler to a Modelica Core library; allowing compilers to become smaller while increasing correctness and portability.
A number of language constructs discussed for Modelica 4 are already supported in some form by the bootstrapped compiler. Future work includes adapting language constructs according to the Modelica 4 design effort and extracting and restructuring parts of the Modelica implementation from the OMC compiler to instead reside in a Modelica Core library; making the compiler smaller and more extensible.
