This commit does a few things at once:
- Updates the tests to contain the latest data from ethereum/tests repo.
- Enables Constantinople state tests. This is needed to be able to
fuzz-test the evm with constantinople rules.
- Fixes the error in opSAR that we've known about for some time. I was
kind of saving it to see if we hit upon it with the random test
generator, but it's difficult to both enable the tests and have the
bug there -- we don't want to forget about it, so maybe it's better
to just fix it.
- Define an Interpreter interface
- One contract can call contracts from other interpreter types.
- Pass the interpreter to the operands instead of the evm.
This is meant to prevent type assertions in operands.
* vm/test: add tests+benchmarks for mstore
* core/vm: less alloc and copying for mstore
* core/vm: less allocs in sload
* vm: check for errors more correctly
* core/vm: track 63/64 call gas off stack
Gas calculations in gasCall* relayed the available gas for calls by
replacing it on the stack. This lead to inconsistent traces, which we
papered over by copying the pre-execution stack in trace mode.
This change relays available gas using a temporary variable, off the
stack, and allows removing the weird copy.
* core/vm: remove stackCopy
* core/vm: pop call gas into pool
* core/vm: to -> addr
