A repository to store Z3-python scripts you can use as examples, reminders, whatever.
If you have such examples, practical or not, feel free to contact me to add them ; would be cool to compile a list of relevant scripts :)!

Hello!
I saw here that Z3 supports having hard and soft constraints using assert-soft
. However, I'm wondering if you know how I can use the python API to do that?
Cheers,

Apologies if this is not the correct place to ask such questions.
from z3 import *
a, b = BitVecs('a b', 32)
c, d = Ints('c d')
solve(a + b == 1337)
solve(c + d == 1337)
s = Solver()
s.add(a + b == 1337)
print s.check()
print s.model()
s = Solver()
s.add(c + d == 1337)
print s.check()
print s.model()
s = Solver()
s.add(a + b == 1337)
s.push()
s.add(a*a == 32)
print s
print s.check()
my test result show me that push&pop operation affect to result.
but It's not what I want. How can I fix it?
can you give hint me why case2 doesn't work??
root@ubuntu:/root# cat test.py
from z3 import *
key = BitVec("tag", 32)
solve(RotateRight(key, 7) == 0x9a000000)
tag = BitVec("tag", 32)
key = BitVecVal(0, 32)
key = key + tag
RotateRight(key, 7)
solve(key == 0x9a000000, tag == 77)
root@ubuntu:/root# ./test.py
[tag = 77]
