From 0eac39d8fbe23770aab341af96bed597443d1e4f Mon Sep 17 00:00:00 2001 From: cl507523 Date: Thu, 26 Feb 2026 11:35:52 +0000 Subject: [PATCH] perf(evm): optimize interpreter dispatch with computed goto and opcode inlining Replace the switch-based opcode dispatch in the interpreter fast path with computed goto (GCC/Clang __label__ extension) for better branch prediction and reduced dispatch overhead. 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 Made-with: Cursor --- src/evm/interpreter.cpp | 782 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 782 insertions(+) diff --git a/src/evm/interpreter.cpp b/src/evm/interpreter.cpp index 7cad3439..92caa6fb 100644 --- a/src/evm/interpreter.cpp +++ b/src/evm/interpreter.cpp @@ -349,6 +349,787 @@ void BaseInterpreter::interpret() { (uint64_t)Frame->Msg.gas >= GasChunkCost[ChunkStartPc]) { const uint32_t ChunkEnd = GasChunkEnd[ChunkStartPc];
