WebJun 23, 2024 · In addition to a JIT compiler, HotSpot embeds an interpreter, which encodes the execution of each JVM bytecode in the most generic way. All methods start executing interpreted, where each bytecode is executed one at a time. Compiled code is tailored to a particular Java method, so optimizations can be applied across bytecode boundaries. WebBytecode verification may be stricter than needed •E.g. It’s might be okay to cast pointers that are still within the SIP’s memory •Benefits of verification: •Faster execution, may be able to elide runtime check! •Type check IPC channels •Need to allow R/W of exchange heap but not SIP’s memory •Do system calls run on SIP’s ...
