|0000750||Frama-C||Kernel > ACSL implementation||public||2011-03-08 17:27||2014-02-12 16:54|
|Target Version||Fixed in Version|
|Summary||0000750: Several [invariant] at a program point|
|Description||If we want to put several [invariant] annotations at a program point, we have to have several ACSL comment, else we get :|
[kernel] user error: Only one code annotation is allowed per comment
But with several comments, several program points are created, and it is then difficult to interpret the invariants, because it seems that they have to be considered as a sequence, while we want to see them as a conjunction...
Would it be possible to have several invariants at the same point like it is done for le [loop invariant] ?
|Tags||No tags attached.|
|This seems reasonable, but requires a change in ACSL specification itself before modifying the implementation.|
In fact, plug-ins can generate several code annotations related to a unique statement. The kind of these code annotations may be different.
An order as been defined between these kinds at the pretty printing:
asserts < stmt contract < invariants < pragmas < loop annotations
but it wasn't used until next commit.
Anyway, something seems to be needed at the ACSL level to ensure re-entrance.
Today, pretty printing a C project having several code annotations at the same points, and parsing that output doesn't produce the same links between stmts and code annotations.
