evmc

• Fixed: [#179] Add missing salt argument for CREATE2 in Host in Go bindings.

• Fixed: [#169] Integration of EVMC as a CMake subproject is easier because Hunter is not loaded unless building tests (EVMC_TESTING=ON) is requested.

The package contains geth 1.8.17 with added EVMC 6.0.0 support and Aleth Interpreter - the EVMC compatible EVM interpreter from Aleth project.

Usage:

./geth --vm.evm=./aleth-interpreter.so
