@gitcoinbot it took some time to understand it. Give me 1 week more. It will be done

@feliam correct me if I am wrong. We need to Implement the basic optimizations mirror or we need to do the things mentioned in todo list?

hey @feliam, ryan from gitcoin here. do you think you could take a look at @aj07's questions? thanks! 😄
@aj07 the idea is to implement the full set of the most common expression optimizations. (cc ryan-shea)

KLEE. Implement the most basic optimizations like the ones yo can find in a compiler: e.g., simple arithmetic simplifications (x + 0 = x), strength reduction (x 2n = x << n), linear simplification (2x - x = x), etc.
There is some optimizations already implemented here: https://github.com/trailofbits/manticore/blob/98190d891d87ac2f3ec3ba5927e6fd4b024cc7e2/manticore/core/smtlib/visitors.py#L351
To consider this issue fixed we need to: 1) Find a good and exhaustive list of common expression simplifications as the ones found in compilers. 2) Implement the rewriting visitors for all of the simplifications using the ones already implemented as inspirational guide. 3) Document each transformation. 4) Add tests for each. Ask the solver to demonstrate the simplified expression is equivalent to the original one. 5) Be sure the
taint
of expressions is maintained in the simplification if required. 6) This should be configurable using config.py 7) Overall symbolic execution performance gain should be measure/tested over a big test set (see https://github.com/trailofbits/manticore/issues/1204)
