    Description

      CODETOOLS-7902854 added support for printing disassembly. Unfortunately, supplying PrintAssembly through compiler directives does not implicitly enables -XX:+DebugNonSafepoints, which makes disassembly less verbose: it misses PcDescs for non-safepoints. See JDK-8264359 for the JDK fix. Meanwhile, we can opt-in to -XX:+DebugNonSafepoints globally.
