TODO list here i keep bullets with future work that i want to do and write about: * find an answer for the following question: what is the shortcoming of old versions of gcc with regards to simplicity? why use them instead of a simple compiler developed later? some context: https://news.ycombinator.com/item?id=30023194 * do an analysis of the different interpretatoins of the ISO standard, e.g. gcc et al. decided to use the interpretation as a basis for optimisation, but what about other optimisations?
