Documentation for tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_state_gas_delegation_pointer.py::test_sstore_direct_call_same_contract@622620d8.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_state_gas_delegation_pointer.py::test_sstore_direct_call_same_contract --fork Amsterdam

Test SSTORE state gas charged when calling the contract directly.

Baseline comparison: calling the contract directly (not via a delegation pointer) charges SSTORE state gas identically.
