This pr copies the optimizations from opbnb: bnb-chain/op-geth#77
several optimizations included:
opcode fusion
jumpdest calculation optimization
SHA caching in interpreter
we observed ~1.2-1.5x speedup in execution time of opbnb mainnet when syncing block at hight ~11m
Description
This PR introduce several optimizations in EVM execution engine, mainly 3 points:
opcode fusion: Combine several hottest opcodes into one super instruction to reduce strength
jumpdest calculation optimizations: reduce the unnecessary jumpdest calculation every time a call happened by leverage caching.
SHA cacheing in interpreter: optimized the SHA opcode to use hash cache that already implemented in geth.
Rationale
To speed up the execution time of contracts and hence enhance the performance.
