My two cents in this interesting discussion: PVS is designed for the 
proof of purely functional (i.e. without side effects at all) 
algorithms. It also involves only mathematical, unbounded, integers and 
real numbers, although some support for machine integers and 
floating-point numbers is available using specific libraries.

Jessie/Why is in principle able to output VCs in PVS syntax for proving 
them inside the PVS environment. Although I'm afraid that it was not 
used for some time and might need some update.

Let me cite the following recent paper about the KB3D case study from 
NASA, and a comparison between the pure PVS code and its C equivalent.

Sylvie Boldo and Thi Minh Tuyen Nguyen. Hardware-independent proofs of 
numerical programs. In C?sar Mu noz, editor, Proceedings of the Second 
NASA Formal Methods Symposium, NASA Conference Publication, pages 14-23,
