Description: Summary by CodeRabbit Bug Fixes Fixed async/await/yield unwind so nested async generators, loops and comprehensions unwind to correct end targets. Resolved jump/branch edge cases so break/continue behave reliably in complex async and generator scenarios. Behavior Improved line-tracing and NOP alignment to preserve accurate tracing and exception mapping across control-flow constructs. Ensured branch targets are computed consistently after instruction-cache entries, improving correctness of control flow. Performance Added inline-cache awareness across compile, JIT and runtime paths for more accurate offsets and steadier execution.
