Dynamic environment binding opcodes lost the old coordinate warmup. They were split away from the static coordinate opcodes. Hot closures and eval-sensitive functions then resolved the same binding by name on every execution, which regressed JS benchmark throughput badly. Give each dynamic environment opcode a per-executable coordinate cache slot. The cache keeps the bytecode stream immutable while letting both interpreters take a direct declarative environment fast path after the first lookup. Keep the existing eval invalidation behavior and only warm caches for declarative-only chains so with environments continue to observe object shadowing. Reject cached bytecode that uses the no-cache sentinel for dynamic environment coordinate cache operands, since execution indexes those cache arrays unconditionally. Rebaseline bytecode expectations for the instruction size changes. Add coverage for with-object shadowing across repeated dynamic lookups and for rejecting corrupt dynamic environment cache indices. |
