Test MCOPY Memory Expansion¶

Generate fixtures for these test cases for Cancun with:

Cancun only:

fill -v tests/cancun/eip5656_mcopy/test_mcopy_memory_expansion.py --fork=Cancun --evm-bin=/path/to/evm-tool-dev-version

For all forks up to and including Cancun:

fill -v tests/cancun/eip5656_mcopy/test_mcopy_memory_expansion.py --until=Cancun

Test copy operations of EIP-5656: MCOPY - Memory copying instruction that produce a memory expansion, and potentially an out-of-gas error.
