qu0b 4a9d210c6e bal: lazy scope allocation in access list builder ... Avoid allocating a map for each EnterScope/ExitScope pair in the BAL access list builder. Precompile STATICCALLs create empty scopes since they don't touch state, but the previous implementation allocated a map[common.Address]*constructionAccountAccess on every enterScope(). For precompile-heavy blocks (e.g. bn128_add at 150 gas = ~200K calls per 30M gas block), this caused 200K unnecessary heap allocations and ~4.8MB of garbage per transaction. The fix pushes nil onto the accessesStack in enterScope() and lazily allocates via currentScope() only when a state change actually occurs. exitScope() short-circuits when the child scope is nil. Benchmark results (precompile calls with no state changes): 100 calls: 5,073 ns → 1,499 ns (3.4x faster, 119 → 19 allocs) 1,000 calls: 47,392 ns → 3,199 ns (14.8x faster, 1019 → 19 allocs) 10,000 calls: 493,651 ns → 20,644 ns (23.9x faster, 10019 → 19 allocs) 100,000 calls: 4,526,165 ns → 192,502 ns (23.5x faster, 100019 → 19 allocs) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-03-16 22:15:01 +00:00
