# revive
|
|
|
|
YUL and EVM assembly recompiler to LLVM, targetting RISC-V on [PolkaVM](https://github.com/koute/polkavm).
|
|
|
|
[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`.
|
|
|
|
## Status
|
|
|
|
This is experimental software in active development and not ready just yet for production usage.
|
|
|
|
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
|
|
|
|
`resolc` depends on the [solc](https://github.com/ethereum/solidity) binary installed on your system.
|
|
|
|
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
|
|
|
|
`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).
|
|
|
|
### 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
|
|
`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).
