描述

Describe the desired feature

Echidna should be able to access implementation contracts via a proxy contract that utilizes delegatecall with msg.data. This will allow easier fuzzing on proxy contracts. Currently, the user needs to create a wrapper for each of the functions that are in the implementation contract.

Ideally, the Slither printer would extract functions that use msg.data and associate the functions of the called contract into the calling contract.

研究方向: First, review the existing Slither printers to understand the pattern. Then, analyze the Solidity AST for delegatecall and msg.data usage. Consider implementing a new printer that outputs functions using these patterns. Check the comments in the issue for additional details.
