Changelog

Unreleased

This is a development pre-release.

Supported polkadot-sdk rev: 2503.0.1

v0.1.0

This is a development pre-release.

Supported polkadot-sdk rev: 2503.0.1

Added

• Add the PolkaVM heap size, stack size and debug info CLI compiler options to the standard JSON settings. This makes the standard JSON input succint for reproducible builds.

Changed

• Supported polkadot-sdk version is now 2503.0.1

Fixed

v0.1.0-dev.16

This is a development pre-release.

Supported polkadot-sdk rev:c29e72a8628835e34deb6aa7db9a78a2e4eabcee

Added

• Move the npm package from paritytech/js-revive, into this repo. The package @parity/resolc will be deployed to npm for each release.
• Support for solc v0.8.30

Changed

• By default, heavy size optimizations are applied.

Fixed

• @parity/resolc: The solc dependency package is constrained to the latest supported version, preventing breaking the package ever time a new solc package was released.
• The resolc npm package no longer ignores the optimizer settings

v0.1.0-dev.14

This is a development pre-release.

Supported polkadot-sdk rev:c29e72a8628835e34deb6aa7db9a78a2e4eabcee

Added

• The revive-runner helper utility binary which helps to run contracts locally without a blockchain node.
• Allow configuration of the EVM heap memory size and stack size via CLI flags and JSON input settings.

Changed

• The default PVM stack memory size was increased from 16kb to 32kb.

Fixed

• Constructors avoid storing zero sized immutable data on exit.

v0.1.0-dev.13

This is a development pre-release.

Supported polkadot-sdk rev:c29e72a8628835e34deb6aa7db9a78a2e4eabcee

Added

• Support for solc v0.8.29
• Decouples the solc JSON-input-output type definitions from the Solidity fronted and expose them via a dedicated crate.
• --supported-solc-versions for resolc binary to return a semver range of supported solc versions.
• Support for passing LLVM command line options via the prcoess input or providing one or more --llvm-arg='..' resolc CLI flag. This allows more fine-grained control over the LLVM backend configuration.

Changed

• Storage keys and values are big endian. This was a pre-mature optimization because for the contract itself it this is a no-op and thus not observable. However we should consider the storage layout as part of the contract ABI. The endianness of transient storage values are still kept as-is.
• Running resolc using webkit is no longer supported.

Fixed

• A missing byte swap for the create2 salt value.

v0.1.0-dev.12

This is a development pre-release.

Supported polkadot-sdk rev: 21f6f0705e53c15aa2b8a5706b208200447774a9

Added

• Per file output selection for --standard-json mode.
• The ir output selection option for --standard-json mode.

Changed

• Improved code size: Large contracts compile to smaller code blobs when enabling aggressive size optimizations (-Oz).

Fixed

v0.1.0-dev.11

This is a development pre-release.

Supported polkadot-sdk rev: 274a781e8ca1a9432c7ec87593bd93214abbff50

Added

Changed

Fixed

• A bug causing incorrect loads from the emulated EVM linear memory.
• A missing integer truncate after switching to 64bit.

v0.1.0-dev.10

This is a development pre-release.

Supported polkadot-sdk rev: 274a781e8ca1a9432c7ec87593bd93214abbff50

Added

• Support for the coinbase opcode.
• The resolc web JS version.

Changed

• Missing the --overwrite flag emits an error instead of a warning.
• The resolc executable prints the help by default.
• Removed support for legacy EVM assembly (EVMLA) translation.
• integration: identify cached code blobs on source code to fix potential confusions.
• Setting base, include or allow paths in emscripten is now a hard error.
• Employ a heuristic to detect address.transfer and address.send calls. If detected, the re-entrant call flag is not set and 0 deposit limit is endowed.

Fixed

• Solidity: Add the solc --libraries files to sources.
• A data race in tests.
• Fix broken pipe errors.
• llvm-builder: Allow warnings.
• solidity: Fix the custom compiler warning messages.

v0.1.0-dev.9

This is a development pre-release.

Added

Changed

• Syscalls with more than 6 arguments now pack them into registers.

Fixed

• Remove reloading of the resolc.js file (fix issue with relative path in web worker)

v0.1.0-dev.8

This is a development pre-release.

Added

• The revive-llvm-builder crate with the revive-llvm helper utility for streamlined management of the LLVM framework dependency.
• Initial support for running resolc in the browser.

Changed

• Suported contracts runtime is polkadot-sdk git version d62a90c8c729acd98c7e9a5cab9803b8b211ffc5.
• The minimum supported Rust version is 1.81.0.
• Error out early instead of invoking solc with invalid base or include path flags.

Fixed

• Decouple the LLVM target dependency from the LLVM host dependency.
• Do not error out if no files and no errors were produced. This aligns resolc closer to solc.
• Fixes input normalization in the Wasm version.

v0.1.0-dev.7

This is a development pre-release.

Added

• Implement the GASPRICE opcode.
• Implement the BASEFEE opcode.
• Implement the GASLIMIT opcode.

Changed

• The GAS opcode now returns the remaining ref_time.
• Contracts can now be supplied call data input of arbitrary size.
• Some syscalls now return the value in a register, slightly improving emitted contract code.
• Calls forward maximum weight limits instead of 0, anticipating a change in polkadot-sdk where weight limits of 0 no longer interprets as uncapped limit.

Fixed

• A linker bug which was preventing certain contracts from linking with the PVM linker.
• JS: Fix encoding conversion from JS string (UTF-16) to UTF-8.
• The git commit hash slug is always displayed in the version string.

v0.1.0-dev.6

This is a development pre-release.

Added

• Implement the BLOCKHASH opcode.
• Implement delegate calls.
• Implement the GASPRICE opcode. Currently hard-coded to return 1.
• The ELF shared object contract artifact is dumped into the debug output directory.
• Initial support for emitting debug info (opt in via the -g flag)

Changed

• resolc now emits 64bit PolkaVM blobs, reducing contract code size and execution time.
• The RISC-V bit-manipulation target feature (zbb) is enabled.

Fixed

• Compilation to Wasm (for usage in node and web browsers)

v0.1.0-dev.5

This is development pre-release.

Added

• Implement the CODESIZE and EXTCODESIZE opcodes.

Changed

• Include the full revive version in the contract metadata.

Fixed

v0.1.0-dev-4

This is development pre-release.

Added

• Support the ORIGIN opcode.

Changed

• Update polkavm to v0.14.0.
• Enable the a, fast-unaligned-access and xtheadcondmov LLVM target features, decreasing the code size for some contracts.

Fixed
