[Frama-c-discuss] YASE \lambda

More generally, is there a simple way to know, both for the Helium and the 
Lithium release, what part of ACSL is implemented? More generally, it 
would be good to know:
- the exact subset of ACSL supported by each release.
- the exact subset of ACSL supported by the Jessie plugin of each release.

Is this documented somewhere? I thought I had understood that the 
non-implemented features were marked as so in the ACSL doucmentation, but 
now I cannot find how.

Thanks,
Jean-Baptiste Jeannin

Re: [Frama-c-discuss] YASE \lambda








Unfortunately, this feature is not expected to be available in the next 
release. Indeed neither \lambda nor \sum. The only thing we can propose 
is a work-around, for providing an ad-hoc (e.g specific for each 
example) equivalent specification.
