WIP. Depends on runtimeverification/evm-semantics#2201.
This PR adds basic support for dynamic arrays used in calldata; it automatically makes calldata symbolic (
selector +Bytes SYMBOLIC_CALLDATA
) if a dynamically-sized type (bytes
,bytes[]
,uint256[]
, etc) is encountered in the function ABI.The original idea was to add the ability to make calldata after a function selector symbolic to support symbolic bytes and dynamic array arguments (e.g., by adding
kevm.symbolicCallData()
andkevm.assumeBytesLength(b, 256)
cheatcodes), but in this case the constraints generated by the compiler at the function entry would still reference the old calldata.At the moment, the PR adds assumptions corresponding to either
