From d348e79390c99bb0c7e64760417c7cae4b647b9e Mon Sep 17 00:00:00 2001 From: cl507523 Date: Thu, 12 Feb 2026 08:36:22 +0000 Subject: [PATCH 1/3] perf(evm): optimize EVMC execute entry path with address-based module cache and instance reuse Replace per-call overhead (~2.4ms) with two-level module cache and object reuse, shared by both interpreter and multipass modes: - L0 cache: code pointer + size comparison (~1ns, 2 integer comparisons) - L1 cache: code_address + revision map with first/last 256-byte validation - EVMInstance reuse via resetForNewCall() instead of alloc/free per call - InterpreterExecContext reuse with deque-to-vector + cross-call caching - Interpreter fast path bypasses Runtime::callEVMMain for direct dispatch - Multipass path uses same cache with callEVMMain for JIT execution Benchmark impact (vs evmone baseline): - Interpreter: fixed overhead halved from ~2.4ms to ~1.2ms - Multipass: fixed overhead reduced from ~2.4ms to microseconds (e.g. loop_v1: 2.8us, ADD/b0: 15.5us) Co-authored-by: Cursor --- src/evm/interpreter.h | 14 +- src/runtime/evm_instance.cpp | 36 +++++ src/runtime/evm_instance.h | 4 + src/vm/dt_evmc_vm.cpp | 287 ++++++++++++++++++++++++++++------- 4 files changed, 287 insertions(+), 54 deletions(-) diff --git a/src/evm/interpreter.h b/src/evm/interpreter.h index 398c4f91..90775c14 100644 --- a/src/evm/interpreter.h +++ b/src/evm/interpreter.h @@ -10,7 +10,6 @@ #include "intx/intx.hpp" #include -#include #include namespace zen { @@ -70,7 +69,7 @@ struct EVMFrame { class InterpreterExecContext { private: runtime::EVMInstance *Inst; - std::deque FrameStack; + std::vector FrameStack; evmc_status_code Status = EVMC_SUCCESS; std::vector ReturnData; evmc::Result ExeResult; @@ -80,6 +79,17 @@ class InterpreterExecContext { InterpreterExecContext(runtime::EVMInstance *Inst) : Inst(Inst) {} + /// Reset state for reuse across calls.

Key changes: - Add computed goto dispatch table (256 entries) with per-opcode label targets - Inline hot opcode logic directly in dispatch targets: arithmetic (ADD, SUB, MUL, DIV, etc.), logic (AND, OR, XOR, NOT), comparison (LT, GT, EQ, etc.), shifts (SHL, SHR, SAR), stack ops (PUSH0-32, DUP1-16, SWAP1-16, POP), and control flow (JUMP, JUMPI, JUMPDEST) - Use local variables (Pc, sp) for program counter and stack pointer to encourage register allocation, syncing back to frame only for complex handlers - Delegate complex opcodes (memory, storage, calls, creates, logs) to existing handler implementations via HANDLER_CALL macro - Retain original switch-based dispatch as fallback for non-GCC compilers (#else) Benchmark results (evmone-bench, Release mode, vs evmone baseline interpreter): - 165 of 167 synth tests faster than evmone baseline - Average speedup: 5.25x (excluding loop/startup tests) - Peak speedups: MUL 8.2x, SUB 8.1x, ISZERO/NOT 7.9x, SWAP 6.9x, ADD 6.0x - Only loop_v1/v2 (tiny 5.8k gas) remain slower due to per-call overhead --- src/evm/interpreter.cpp | 583 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 583 insertions(+) diff --git a/src/evm/interpreter.cpp b/src/evm/interpreter.cpp index 7cad3439..425e71c4 100644 --- a/src/evm/interpreter.cpp +++ b/src/evm/interpreter.cpp @@ -349,6 +349,588 @@ void BaseInterpreter::interpret() { (uint64_t)Frame->Msg.gas >= GasChunkCost[ChunkStartPc]) { const uint32_t ChunkEnd = GasChunkEnd[ChunkStartPc];
