Dependent types were111 We plan to depart from CompCert when carrying out our proof since we want to 112 experiment different proof strategies where possible. In particular, we will 113 try to exploit dependent types in our formalisation, as dependent types were 113 114 avoided as a design principle in CompCert. For this reason, we have already 114 started to formali ze in Matita the intermediate languages of our compiler115 started to formalise in Matita the intermediate languages of our compiler, 115 116 recording invariants in the types themselves and rearranging some code. 116 117 This should be completed at month 18. At this point we will be able to 117 118 correctly state the intermediate proof statements and to estimate the 118 complexity and effort for the formalization.119 complexity and effort needed for the formalisation. 119 120 120 \item The reviewers suggest touse this estimation to compare two possible121 \item The reviewers suggest we use this estimation to compare two possible 121 122 scenarios: a) proceed as planned, porting all CompCert proofs to Matita or 122 123 b) port D3.1 and D4.1 to Coq and reuse the CompCert proofs.
