Most of these changes are directly useful for the MontiumC +compiler, some only indirectly. Examples of these improvements include better +support for struct types, better documentation of the testing framework and a +lot of small fixes and changes to make LLVM more flexible and extendable. + +\subsection{MontiumC improvements} +Improvements made to the MontiumC language are mostly limited to making the +langauge better specified. Things which had limited support now either have full +support, or were removed from the language. + +Usage of global variables, struct variables, arguments and returns values and +constant arguments is now possible in most cases, where it only was possible in +some specific cases before. + +Additionally, there has been some experimenting with new MontiumC features, such +as C style memory access and loops. So far, these features have not received +enough work in both the frontend as the backend to be supported in the language +yet. + +\subsection{Frontend improvements} +The MontiumC frontend has seen a lot of improvements. + +Part of these improvements are to make the language more stable. This was mostly +done by completely reviewing the set of LLVM transformation passes and selecting +a subset that fits the MontiumC language. Addtionally, some transformation +passes were added, which also make the backend simpler (for example, +reducing variable lifetimes, global variable removal, function specialization). + +Other improvements cause the frontend to become more usable as a program. These +include improved error handling, extra configurability through commandline +options and support for linking multiple files together. -- 2.30.2
