Documentation for tests/cancun/eip1153_tstore/test_basic_tload.py::test_basic_tload_works@a86d4327.
Generate fixtures for these test cases for Cancun with:
Cancun only:
fill -v tests/cancun/eip1153_tstore/test_basic_tload.py::test_basic_tload_works --fork=Cancun --evm-bin=/path/to/evm-tool-dev-version
For all forks up to and including Cancun:
fill -v tests/cancun/eip1153_tstore/test_basic_tload.py::test_basic_tload_works --until=Cancun
Ported .json vectors:
(02_tloadAfterTstoreFiller.yml)
tload from same slot after tstore returns correct value
