evmone 0.10.0

The highlights of this release are support for Shanghai execution specification upgrade and implementation of EOF "v1.0". There are also big enhancements to the EVM testing tools and infrastructure. In particular, we added the t8n command-line utility.

As it is tradition, the EVM performance has been improved as well. Comparing with the previous release using the "main" benchmark suite, the Baseline interpreter is now:

• 10–45% (mean 25%) faster for GCC builds,
• 0–19% (mean 11%) faster for Clang builds.

Added

• Shanghai support:
  • EIP-3651: Warm COINBASE (testing infrastructure only). #560
  • EIP-3860: Limit and meter initcode. #545
  • EIP-4895: Beacon chain push withdrawals as operations (testing infrastructure only). #614
• EVM Object Format "EOF v1.0":
  • The implementation of the revisions of EIP-3540, EIP-3670, EIP-4200, EIP-4750 and EIP-5450 originally proposed for Shanghai. #563 #572 #594 #508
  • EOF is currently enabled in the Cancun revision but likely to be moved to Prague in the future. #561
  • Added evmone-eofparse and evmone-eofparsefuzz tools for testing EOF validation. #568
• Implemented EIP-663: Unlimited SWAP and DUP instructions (enabled in EOF). #529
• Added implementation of evmc::Host, state transition and block finalization for testing purposes. #484 #519 #575 #608 #609
• Added t8n tool evmone-t8n — a command line utility for transaction execution and state transition testing. It allows executing and generating tests with cooperation of retesteth or execution-spec-tests. #552 #555 #558 #569 #583 #590 #591 #604 #606 #607 #612
• Added partial support for EVM Precompiles — gas cost computation and execution via JSON stub file. #524
• Declarative state transition unit test suite. #589
• CMake option EVMONE_X86_64_ARCH_LEVEL to set the x86-64 microarchitecture level. On Linux and Windows this is set to x86-64-v2 by default. #548
