Nikolaj Bjorner 8ff1e44a95 add discriminator to whether context contains recursive functions to avoid enabling recursive function solver when there are just macros 2022-11-06 11:58:21 -08:00
Nikolaj Bjorner 36d76a5bb2 fix #6304 
Conditionals are used to guard unfolding of recursive functions.
This is, as shown in #6304, incompatible with the case where recursive functions are used inside if-then-else guards.
We address this by disabling if-conditions as guards if they contain a recursive definition.
The approach is simplistic: if a recursive function, defined prior (not mutually recursive) is used in a guard it should be fine and the condition can guard the current recursive unfolding.

Nikolaj Bjorner 0353fc38ff fix #6127 again 
this time adding inheritance to the recfun plugin so it properly contains the recursive definitions from the source.

Nuno Lopes e844aef896 remove a few more copy constructors, though still not enough to enable the assertion in vector 
I give up for now; there are too many copies left for little return..
