Hello Claude,

It seems it is, because Pascal's example works for me.

In both the acsl-beryllium2 and the acsl-boron documentation terminates
is marked as "Experimental" in section "2.5.4 Non-terminating
functions". If it is not supported yet, it should be indicated. I
understand "Experimental" as something that has been implemented, but
may not work in all circumstances.

If pragma JessieTerminationPolicy is implemented in Boron, it should be
mentionen in section "2.5.4 Non-terminating functions" of the acsl-boron
documentation. So far, it is only mentioned in the Jessie-tutorial.
