[Frama-c-discuss] arbitrary buffers in analysis



ps: I think it would be a great feature addition to have a way
to directly force such properties as axioms to some analysis
instead of having to code them up using Frama_C_*()
primitives (using the entropy source).  I imagine this would
ease the analysis too, since it wouldn't waste time having to
analyze this extra boilerplate whose only purpose was to
set a predetermined analysis state.

Thoughts?
