Reduce KERNEL size to allow initial
MemBefore
to fit in2^16
rows (currently padded to 2^17).Also address the TODO on
gas_hook
, as we haven't had any gas discrepancies since full completion of the Ethereum test suite, and this is saving a couple hundred thousand cycles for mainnet blocks (while also reducing KERNEL code size).Most of the savings are around removing the heavy PUSHes (for large values), and reordering stack elements.
Current KERNEL code size as of 3a220c1:
eth_mainnet
: 64559cdk_erigon
: 63858 (though this will probably go over the limit again once plugging thesmt
code)Ran through the Ethereum test suite for consistency
