TRON Compiler Solidity v0.8.18 is fully compatible with Ethereum Solidity Compiler v0.8.18.
In addition, this release supports new instructions and precompile contracts introduced in TIP-467.
Please see the Solidity example to use.

Requirement

  • Developers can only use these new instructions and precompile contracts after the related proposal has been approved on TRON mainnet.

New Features from TRON:

  • TVM: Introduce freezebalancev2(uint256,uint256) in Solidity.
  • TVM: Introduce unfreezebalancev2(uint256,uint256) in Solidity.
  • TVM: Introduce cancelallunfreezev2() in Solidity.
  • TVM: Introduce withdrawexpireunfreeze() in Solidity.
  • TVM: Introduce <address payable>.delegateResource(uint256,uint256) in Solidity.
  • TVM: Introduce <address payable>.unDelegateResource(uint256,uint256) in Solidity.
  • TVM: Introduce new magic type chain in Solidity and the parameters that can be queried include chain.totalNetLimit, chain.totalNetWeight, chain.totalEnergyCurrentLimit, chain.totalEnergyWeight and chain.unfreezeDelayDays.
  • TVM: Introduce <address>.availableUnfreezeV2Size() in Solidity.
  • TVM: Introduce <address>.unfreezableBalanceV2(uint256) in Solidity.
  • TVM: Introduce <address>.expireUnfreezeBalanceV2(uint256) in Solidity.
  • TVM: Introduce <address>.delegatableResource(uint256) in Solidity.
  • TVM: Introduce <address>.resourceV2(address,uint256) in Solidity.
  • TVM: Introduce <address>.checkUnDelegateResource(address,uint256) in Solidity.
  • TVM: Introduce <address>.resourceUsage(uint256) in Solidity.
  • TVM: Introduce <address>.totalResource(uint256) in Solidity.
  • TVM: Introduce <address>.totalDelegatedResource(uint256) in Solidity.
  • TVM: Introduce <address>.totalAcquiredResource(uint256) in Solidity.

Important Bugfixes:

  • Code Generator: Correctly encode literals used in abi.encodeCall in place of fixed bytes arguments.
  • ABI Encoder: When ABI-encoding values from calldata that contain nested arrays, correctly validate the nested array length against calldatasize() in all cases.
  • Override Checker: Allow changing data location for parameters only when overriding external functions.
  • Code Generation: Avoid writing dirty bytes to storage when copying bytes arrays.
  • Yul Optimizer: Keep all memory side-effects of inline assembly blocks.
  • Code Generation: Fix data corruption that affected ABI-encoding of calldata values represented by tuples: structs at any nesting level; argument lists of external functions, events and errors; return value lists of external functions. The 32 leading bytes of the first dynamically-encoded value in the tuple would get zeroed when the last component contained a statically-encoded array.
  • Yul Optimizer: Prevent the incorrect removal of storage writes before calls to Yul functions that conditionally terminate the external EVM call.

Language Features:

  • General: Add equality-comparison operators for external function types.
  • General: Support ContractName.functionName for abi.encodeCall, in addition to external function pointers.
  • General: Allow annotating inline assembly as memory-safe to allow optimizations and stack limit evasion that rely on respecting Solidity's memory model.
  • General: using M for Type; is allowed at file level and M can now also be a brace-enclosed list of free functions or library functions.
  • General: using ... for T global; is allowed at file level where the user-defined type T has been defined, resulting in the effect of the statement being available everywhere T is available.
  • Add E.selector for a non-anonymous event E to access the 32-byte selector topic.
  • Support using library constants in initializers of other constants.
  • Allow named parameters in mapping types.

Compiler Features:

  • EVM: Deprecate block.difficulty and disallow difficulty() in inline assembly for EVM versions >= paris. The change is due to the renaming introduced by EIP-4399.
  • EVM: Introduce block.prevrandao in Solidity and prevrandao() in inline assembly for EVM versions >= paris.
  • EVM: Set the default EVM version to "Paris".
  • EVM: Support for the EVM version "Paris".
  • TypeChecker: Warn when using deprecated builtin selfdestruct.

Build System:

  • Emscripten builds store the embedded WebAssembly binary in LZ4 compressed format and transparently decompress on loading.
  • Allow disabling pedantic warnings and do not treat warnings as errors during compiler build when -DPEDANTIC=OFF flag is passed to CMake.
  • Update emscripten to version 3.1.19.
