+# Changelog
+
+## Unreleased
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `274a781e8ca1a9432c7ec87593bd93214abbff50`
+
+## 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

 `resolc` depends on the [solc](https://github.com/ethereum/solidity) binary installed on your system.

+Download and install the `resolc` frontend executable for your platform from our [releases](https://github.com/paritytech/revive/releases).
+
+## Building from source
+
+Building revive requires a [stable Rust installation](https://rustup.rs/) and a C++ toolchain for building [LLVM](https://github.com/llvm/llvm-project) on your system.
+
+### LLVM
+
+`revive` depends on a custom build of LLVM `v18.1.8` with the RISC-V _embedded_ target, including the `compiler-rt` builtins. Use the provided [revive-llvm](crates/llvm-builder/README.md) utility to compile a compatible LLVM build locally and point `$LLVM_SYS_181_PREFIX` to the installation afterwards.
+
+The `Makefile` provides a shortcut target to obtain a compatible LLVM build:
+
+```bash
+make install-llvm
+export LLVM_SYS_181_PREFIX=${PWD}/target-llvm/gnu/target-final
+```
+
+### The `resolc` Solidity frontend
+
+To build the `resolc` Solidity frontend executable, make sure you have obtained a compatible LLVM build using [revive-llvm](crates/llvm-builder/README.md) and did export the `LLVM_SYS_181_PREFIX` environment variable pointing to it (see [above](#LLVM)).
+
 To install the `resolc` Solidity frontend executable:

 ```bash
-bash build-llvm.sh
-export PATH=${PWD}/llvm18.0/bin:$PATH
 make install-bin
 resolc --version
 ```

-### LLVM
+### Cross-compilation to Wasm

-`revive` requires a build of LLVM 18.1.4 or later including `compiler-rt`. Use the provided [build-llvm.sh](build-llvm.sh) build script to compile a compatible LLVM build locally in `$PWD/llvm18.0` (don't forget to add that to `$PATH` afterwards). 
+Cross-compile the `resolc.js` frontend executable to Wasm for running it in a Node.js or browser environment. The `REVIVE_LLVM_TARGET_PREFIX` environment variable is used to control the target environment LLVM dependency.
+
+```bash
+# Build the host LLVM dependency with PolkaVM target support
+make install-llvm
+export LLVM_SYS_181_PREFIX=${PWD}/target-llvm/gnu/target-final
+
+# Build the target LLVM dependency with PolkaVM target support
+revive-llvm --target-env emscripten clone
+source emsdk/emsdk_env.sh
+revive-llvm --target-env emscripten build --llvm-projects lld
+export REVIVE_LLVM_TARGET_PREFIX=${PWD}/target-llvm/emscripten/target-final
+
+# Build the resolc frontend executable
+make install-wasm
+make test-wasm
+```

 ### Development

 Ensure that your branch passes `make test` locally when submitting a pull request.

 ## Design overview
+
 `revive` uses [solc](https://github.com/ethereum/solidity/), the Ethereum Solidity compiler, as the [Solidity frontend](crates/solidity/src/lib.rs) to process smart contracts written in Solidity. The YUL IR code (or legacy EVM assembly as a fallback for older `solc` versions) emitted by `solc` is then translated to LLVM IR, targetting [Polkadots `revive` pallet](https://docs.rs/pallet-revive/latest/pallet_revive/trait.SyscallDoc.html).
+[Frontend](https://github.com/matter-labs/era-compiler-solidity) and [code generator](https://github.com/matter-labs/era-compiler-llvm-context) are based of ZKSync `zksolc`.
+
+## Tests
+
+Before running the tests, ensure that Geth (Go Ethereum) is installed on your system. Follow the installation guide here: [Installing Geth](https://geth.ethereum.org/docs/getting-started/installing-geth).
+Once Geth is installed, you can run the tests using the following command:

+# Release checklist
+
+Prior to the first stable release we neither have formal release processes nor do we follow a fixed release schedule.
+
+To create a new pre-release:
+
+1. Merge a release PR which updates the `-dev.X` versions in the workspace `Cargo.toml` and updates the `CHANGELOG.md` accordingly
+2. Push a release tag to `main`
+3. Create a __pre-release__ from the tag and manually upload the `resolc` binary from docker image
+4. Manually upload `resolc.js`, `resolc-web.js` and `resolc.wasm` from the `build-revive-wasm` action artifacts.
+5. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly

+- [Libraries with public functions are not supported](https://github.com/paritytech/revive/issues/91)
+- [Automatic import resolution is not supported](https://github.com/paritytech/revive/issues/98)
+- The emulated EVM linear contract memory is limited to 64kb in size. Will be fixed with support for metered dynamic memory.
+- [The contract calldata is currently limited to 1kb in size](https://github.com/paritytech/revive/issues/57)
+- [EIP-4844 opcodes are not supported](https://github.com/paritytech/revive/issues/64)
+- [Delegate calls are not supported](https://github.com/paritytech/revive/issues/67)

+- [The `extcodesize` opcode is not supported](https://github.com/paritytech/revive/issues/58)
+- [The `origin` opcode is not supported](https://github.com/paritytech/revive/issues/59)
+- [Gas limits for contract calls are ignored](https://github.com/paritytech/revive/issues/60)
+- [Gas related opcodes are not supported](https://github.com/paritytech/revive/issues/60)
+- IPFS metadata hashes are not supported
+- [Compiled contract artifacts can exceed the pallet static memory limit and fail to deploy](https://github.com/paritytech/revive/issues/96).
+- [Transfers to inexistant accounts will fail if the transferred value lies below the ED.](https://github.com/paritytech/revive/issues/83) Will be fixed in the pallet to make the ED completely transparent for contracts.
+
+## Wontfix
+
+Please consult our documentation to learn more about Solidity and EVM features likely to remain unsupported (and why they will not be supported).
+
+TODO: Insert link to the relevant documentation section.

+# revive LLVM builder
+
+Parity fork of the [Matter Labs zksync LLVM builder](https://github.com/matter-labs/era-compiler-llvm-builder) helper utility for compiling [revive](https://github.com/paritytech/revive) compatible LLVM builds.
+
+## Installation and usage
+
+The LLVM compiler framework for revive must be built with our tool called `revive-llvm`.
+This is because the revive compiler has requirements not fullfilled in upstream builds:
+- Special builds for compiling the frontend into statically linked ELF binaries and also Wasm executables
+- The RISC-V target (the PolkaVM target)
+- The compiler-rt builtins for the PolkaVM target
+- We want to leave the assertions always on
+- Various other specific configurations and optimization may be applied
+
+Obtain a compatible build for your host platform from the release section of this repository (TODO). Alternatively follow below steps to get a custom build:
+
+<details>
+<summary>1. Install the system prerequisites.</summary>
+
+   * Linux (Debian):
+
+      Install the following packages:
+      ```shell
+      apt install cmake ninja-build curl git libssl-dev pkg-config clang lld
+      ```
+   * Linux (Arch):
+
+      Install the following packages:
+      ```shell
+      pacman -Syu which cmake ninja curl git pkg-config clang lld
+      ```
+
+   * MacOS:
+
+      * Install the [HomeBrew](https://brew.sh) package manager.
+      * Install the following packages:
+
+         ```shell
+         brew install cmake ninja coreutils
+         ```
+
+      * Install your choice of a recent LLVM/[Clang](https://clang.llvm.org) compiler, e.g. via [Xcode](https://developer.apple.com/xcode/), [Apple’s Command Line Tools](https://developer.apple.com/library/archive/technotes/tn2339/_index.html), or your preferred package manager.
+</details>
+
+<details>
+<summary>2. Install Rust.</summary>
+
+   * Follow the latest [official instructions](https://www.rust-lang.org/tools/install:
+      ```shell
+      curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+      . ${HOME}/.cargo/env
+      ```
+
+      > Currently we are not pinned to any specific version of Rust, so just install the latest stable build for your   platform.
+</details>
+
+<details>
+<summary>3. Install the revive LLVM framework builder.</summary>
+
+   * Install the builder using `cargo`:
+      ```shell
+      cargo install --git https://github.com/paritytech/revive-llvm-builder --force --locked
+      ```
+
+      > The builder is not the LLVM framework itself, but a tool that clones its repository and runs a sequence of build commands. By default it is installed in `~/.cargo/bin/`, which is recommended to be added to your `$PATH`.
+
+</details>
+
+<details>
+<summary>4. (Optional) Create the `LLVM.lock` file.</summary>
+
+   * The `LLVM.lock` dictates the LLVM source tree being used.
+     A default `./LLVM.lock` pointing to the release used for development is already provided.
+
+</details>
+
+<details>
+<summary>5. Build LLVM.</summary>
+
+   * Clone and build the LLVM framework using the `revive-llvm` tool.
+
+     The clang and lld projects are required for the `resolc` Solidity frontend executable; they are enabled by default. LLVM assertions are also enabled by default.
+
+      ```shell
+      revive-llvm clone
+      revive-llvm build --llvm-projects lld --llvm-projects clang
+      ```
+
+      Build artifacts end up in the `./target-llvm/gnu/target-final/` directory by default.
+      The `gnu` directory depends on the supported archticture and will either be `gnu`, `musl` or `emscripten`.
+      You now need to export the final target directory `$LLVM_SYS_181_PREFIX`: `export LLVM_SYS_181_PREFIX=${PWD}/target-llvm/gnu/target-final`
+      If built with the `--enable-tests` option, test tools will be in the `./target-llvm/gnu/build-final/` directory, along with copies of the build artifacts. For all supported build options, run `revive-llvm build --help`.
+
+</details>
+
+## Supported target architectures
+
+The following target platforms are supported:
+- Linux GNU (x86)
+- Linux MUSL (x86)
+- MacOS (aarch64)
+- Windows GNU (x86)
+- Emscripten (wasm32)
+
+<details>
+<summary>Building for MUSL</summary>
+
+   * Via a musl build we can build revive into fully static ELF binaries.
+     Which is desirable for reproducible Solidity contracts builds.
+     The resulting binary is also very portable, akin to the`solc` frontend binary distribution.
+
+     Clone and build the LLVM framework using the `revive-llvm` tool:
+      ```shell
+      revive-llvm --target-env musl clone
+      revive-llvm --target-env musl build --enable-assertions --llvm-projects clang --llvm-projects lld 
+      ```
+
+</details>
+
+<details>
+<summary>Building for Emscripten</summary>
+
+   * Via an emsdk build we can run revive in the browser and on node.js.
+
+     Clone and build the LLVM framework using the `revive-llvm` tool:
+      ```shell
+      revive-llvm --target-env emscripten clone
+      revive-llvm --target-env emscripten build --enable-assertions --llvm-projects clang --llvm-projects lld 
+      ```
