  • Cheatcode for generating a symbolic byte array, including limited support for a symbolic length as well
  • New tests for generating symbolic byte array with this cheatcode, checking the length, passing it to a function which overwrites some parts of it, and generating a symbolic byte array with symbolic length.

Blocked on this KEVM PR.

N.B. The FreshBytesTest.test_symbolic_bytes_2 does not pass yet (but should eventually) due to high complexity of the associated symbolic reasoning. This, however, is orthogonal to the correct generation of symbolic bytes, which is tested by the other two tests.
