Nikolaj Bjorner 17545233e6 encapsulate anum functionality 2024-01-20 12:59:58 -08:00
Nikolaj Bjorner 548be4c1f9 add explicit move constructor to deal with unit test regression test-z3 algebraic on Windows/debug - 
it uses copy constructor instead of move when returning a scoped_anum in functions such as power and root.
This leads to freeing memory that gets passed as return value.

The copy constructor for scoped_numeral is also suspicious because it doesn't ensure memory ownership.

Fix some typos. (#7075) 2023-12-29 15:20:06 +00:00
Jakob Rath ec2b8eb4ca
Merge shared parts from polysat branch (#7063) 
* sat_literal: make constants constexpr

* dlist: rename elem -> list

* tbv: use get_bit

* additional pdd and rational tests

* egraph: callback setters take functions by value

This allows to set callbacks without defining a separate variable for
the callback lambda.

(previous usage does one copy of the function, exactly as before)

* cmake: enable compiler error when non-void function does not return value
