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

Nikolaj Bjorner b52fd8d954 add EUF plugin framework. 
plugin setting allows adding equality saturation within the E-graph propagation without involving externalizing theory solver dispatch. It makes equality saturation independent of SAT integration.
Add a special relation operator to support ad-hoc AC symbols.

cmake: Use FindPython3. (#7019) 
`FindPythonInterp` has been deprecated for a long time and is more
verbal about that deprecation now.

The build system no longer uses `PYTHON_EXECUTABLE` but instead uses
`Python3_EXECUTABLE`.

Nikolaj Bjorner b9455c3692 #6999 deal with implicit assumptions, more robust pattern matching 
The code is making some assumptions that arrays are 1-dimensional. This is not generally true.
Introducing pattern matching to ensure the assumption is met.
Avoid get_arg(..) especially when there is an approach based on pattern matching recognizers.
