# Changelog ## Unreleased 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. - Runner `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
