Merge branch 'main' into cl/optsize

- Add support for the YUL optimizer details in the standard json input
definition.
- Make optimizer settings optional. They can be omitted and solc will
pick default values ([see here for
reference](https://docs.soliditylang.org/en/latest/using-the-compiler.html#input-description)).

For example allows to use the
[`yul-phaser`](https://github.com/ethereum/solidity/blob/0917604a5ec7cff8bd40a1137f4fcb303fb90527/tools/yulPhaser/README.md?plain=1)
utility. I did a single search with slightly adjusted costs (just made
some educated guess) and after an hour or so this already found an
optimizer sequence
(`OESsShMxeoufcSTvlFxtelTfnfEvicdFxnsvopgCaIeLcnvsTtUrUgdVTUttaeUomccTTTuujsVVvVDvvueUrTjUOmjrrhuuTtj`)
which shrinks the size of the `EndpointV2.sol` from LayerZero by 10%.

 ## Unreleased
 
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+## v0.4.0
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+### Added
+- Line debug information per YUL builtin and for `if` statements.
+- Support for the YUL optimizer details in the standard json input definition.
+
+### Fixed
+- The debug info source file matches the YUL path in `--debug-output-dir`, allowing tools to display the source line. 
+
+## v0.3.0
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+### Fixed
+
+- llvm-context: Bugfix the SAR YUL builtin translation.
+- runtime-api: Add the missing `memset` builtin.
+- npm package: Bugfix the exports field defined in the `package.json`.
+
+
+## v0.2.0
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+### Changed
+
+- Removed the license printer from the `resolc` binary.
+- EVM bytecode is no longer requested from solc (except in test utils) leading to less compilation work in the pipeline.
+
+### Fixed
+
+- solc-json-interface: Serializing of any custom key in the JSON input is only skipped if not provided.
+- npm package resolution no longer fails with an 'ERR_PACKAGE_PATH_NOT_EXPORTED' error for packages defining exports fields in the `package.json`.
+
+## 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`
+- The `emsdk` version is now `4.0.9`
+
+### 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.

+This is experimental software in active development and not ready just yet for production usage. Please do report any compiler related issues or missing features that are [not yet known to us](https://contracts.polkadot.io/known_issues/) here.
 
 Discussion around the development is hosted on the [Polkadot Forum](https://forum.polkadot.network/t/contracts-update-solidity-on-polkavm/6949#a-new-solidity-compiler-1).
 
 ## Installation
+Building Solidity contracts for PolkaVM requires installing the following two compilers:
+- `resolc`: The revive Solidity compiler YUL frontend and PolkaVM code generator (provided by this repository).
+- `solc`: The [Ethereum Solidity reference compiler](https://github.com/ethereum/solidity/) implemenation.`resolc` uses `solc` during the compilation process, please refer to the [Ethereum Solidity documentation](https://docs.soliditylang.org/en/latest/installing-solidity.html) for installation instructions.
 
-`resolc` depends on the [solc](https://github.com/ethereum/solidity) binary installed on your system.
+### `resolc` binary releases
+`resolc` is distributed as a standalone binary (with `solc` as the only external dependency). Please download one of our [binary releases](https://github.com/paritytech/revive/releases) for your target platform and mind the platform specific instructions below.
+
+<details>
+  <summary>MacOS users</summary>
+
+> **MacOS** users need to clear the `downloaded` attribute from the binary and set the executable flag.
+> ```sh
+> xattr -rc resolc-universal-apple-darwin
+> chmod +x resolc-universal-apple-darwin
+> ```
+
+</details>
+
+<details>
+  <summary>Linux users</summary>
+
+> **Linux** users need to set the executable flag.
+> ```sh
+> chmod +x resolc-x86_64-unknown-linux-musl
+> ```
+
+</details>
+
+
+### `resolc` NPM package
+We distribute the revive compiler as [node.js module](https://www.npmjs.com/package/@parity/resolc) and [hardhat plugin](https://www.npmjs.com/package/@parity/hardhat-polkadot-resolc).
+
+Note: The `solc` dependency is bundled via NPM packaging and defaults to the latest supported version.
+
+## 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. You can either download a build from our releases (recommended for older hardware) or build it from source.
+
+<details>
+  <summary>Download from our LLVM releases</summary>
+
+Download the [latest LLVM build](https://github.com/paritytech/revive/releases?q=LLVM+binaries+release&expanded=true) from our releases.
+
+> **MacOS** users need to clear the `downloaded` attribute from all binaries after extracting the archive:
+> ```sh
+> xattr -rc </path/to/the/extracted/archive>/target-llvm/gnu/target-final/bin/*
+> ```
+
+After extracting the archive, point `$LLVM_SYS_181_PREFIX` to it:
+```sh
+export LLVM_SYS_181_PREFIX=</path/to/the/extracted/archive>/target-llvm/gnu/target-final
+```
+
+</details>
+
+<details>
+  <summary>Building from source</summary>
+
+ Use the provided [revive-llvm](crates/llvm-builder/README.md) utility to compile a compatible LLVM build locally and point `$LLVM_SYS_181_PREFIX` to the installation afterwards.
+
+The `Makefile` provides a shortcut target to obtain a compatible LLVM build:
+
+```sh
+make install-llvm
+export LLVM_SYS_181_PREFIX=${PWD}/target-llvm/gnu/target-final
+```
+
+</details>
+
+### The `resolc` Solidity frontend
+
+To build the `resolc` Solidity frontend executable, make sure you have obtained a compatible LLVM build and did export the `LLVM_SYS_181_PREFIX` environment variable pointing to it (see [above](#LLVM)).
 
 To install the `resolc` Solidity frontend executable:
 
-```bash
+```sh
-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.
 
-### Development
+<details>
+  <summary>Instructions for cross-compilation to wasm32-unknown-emscripten</summary>
+
+```sh
+# 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
+```
+
+</details>
+
+## Development
 
 Please consult the [Makefile](Makefile) targets to learn how to run tests and benchmarks. 
 Ensure that your branch passes `make test` locally when submitting a pull request.
 
-## Design overview
+### 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).
+See the [relevant section in our documentation](https://contracts.polkadot.io/revive_compiler/architecture) to learn more about how the compiler works. 
+
+### 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:
+
+```sh
+make test
+```
+# Acknowledgements
+
+The revive compiler project, after some early experiments with EVM bytecode translations, decided to fork the `era-compiler` framework.
+[Frontend](https://github.com/matter-labs/era-compiler-solidity), [code generator](https://github.com/matter-labs/era-compiler-llvm-context) and some supporting libraries are based of ZKSync `zksolc`. I'd like to express my gratitude and thank the original authors for providing a useable code base under a generous license.

+1. Create a release PR which, if necessary:
-2. Push a release tag to `main`
+  - Updates the versions in the workspace `Cargo.toml`
-3. Manually trigger the `Build revive-debian` action
+  - Updates the version in each crate `Cargo.toml`
-4. Create a __pre-release__ from the tag and manually upload the build artifact generated by the action
+  - Updates the version of the NPM package in `js/resolc/package.json`
-5. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly

+2. If the CI passes, merge the release PR.
+3. Push a `vX.Y.Z` tag that has the same version as in `Cargo.toml`
+4. The release workflow will attempt to build and publish a new pre-release if the latest tag does match the cargo package version.
+5. Wait for the `Release` workflow to finish. It should create the pre-release with the same name.
+6. Check that pre-release was created on the [Releases page](https://github.com/paritytech/revive/releases) with all artifacts.
+7. After the release is published, another workflow should start automatically and update json files in https://github.com/paritytech/resolc-bin. Check the changes.
+8. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly
+
+# `resolc` NPM package release
+
+Will happen automatically.
+
+# LLVM release
+
+To create a new LLVM release, run "Release LLVM" workflow. Use current LLVM version as parameter, e.g. `18.1.8`.
+Version suffix will be resolved automatically.  
+The workflows will create new GitHub release, and upload LLVM binaries.
+Next release of resolc will use newly created binaries.

+# 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 
+      ```
