Storage keys and values are big endian. Keeping them LE 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. --------- Signed-off-by: Cyrill Leutwiler <bigcyrill@hotmail.com>

|
|
|
## 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.

|
|
- Runner `resolc` using webkit is no longer supported.
|
|
|
|
### Fixed
|
|
- A missing byte swap for the create2 salt value.

|
|

|
|
|
|
This is a development pre-release.

## 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.
|
|

|
|
- 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.
|
|
|

|
|
|
|
# Added

|
|

|
|

|
|

|
|
- 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.
|
|
|

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