Duplicated JITTed code brings overhead for the instruction cache. This patch reduces duplication by JITting inlined function separately if trace is too long because the same function is JITTed in different root trace or side trace sometimes. It increases 2%~3% performance of our workload in tracing mode. Signed-off-by: Wang, Xue <[email protected]> Signed-off-by: Yang, Lin A <[email protected]> Signed-off-by: Su, Tao <[email protected]>
