Summary: We present a program logic for virtual machine code that may serve as a suitable target for different proof-transforming compilers. Compilation from JML-specified source code is supported by the inclusion of annotations whose interpretation extends to non-terminating computations. Compilation from functional languages, and the communication of results from intermediate level program analysis phases are facilitated by a new judgement format that admits the compositionality of type systems to be reflected in derivations. This makes the logic well suited to serve as a language in which proofs of a PCC architecture are expressed. We substantiate this claim by presenting the compositional encoding of a type system for bounded heap consumption. Both the soundness proof of the logic and the derivation of the type system have been formally verified by an implementation in Isabelle/HOL.
