    <p>My understanding is that they are similar, but disable different

      optimizations.  A blackhole is to disable dead-code elimination,

      while ensureMaterializedForStackWalk is to disable scalarization.</p>

      <div dir="ltr">Hello,<br>

        <br>

        I am trying to understand the JDK20 intrinsic -

        Thread.ensureMaterializedForStackWalk (<a href="https://github.com/openjdk/jdk/pull/10952/files" moz-do-not-send="true" class="moz-txt-link-freetext">https://github.com/openjdk/jdk/pull/10952/files</a>).<br>

        <br>

        It seems to be functionally equivalent to the <i>Blackhole.consume</i>

        intrinsic. <br>

        <br>

        Is there any subtle difference(s) between the two, or can one be

        implemented using the other? <br>

        <br>

        Thanks in advance.<br>

        Shami.<br>
