ERC20Permit.constructor(string).name (#1099) shadows:
- (#659-661) (function)
- (#584) (function)
Rename the local variables that shadow another component.

Variable 'ECDSA.tryRecover(bytes32,bytes).r (#175)' in ECDSA.tryRecover(bytes32,bytes) (#170-199) potentially used before declaration: r = mload(uint256)(signature + 0x20) (#192)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (#1104-1123) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (#1113)
Avoid relying on block.timestamp.
