<p>Back to 3 unit test fails with VMMaker generated arm64 FFI!</p>

<p><span class="css-truncate css-truncate-target">Two basic problems.</span></p>
<p><span class="css-truncate css-truncate-target"> [1] Somehow, StackInterpreter lost some of its class variable values (e.g. for DisownVM).<br /></span></p>
<p><span class="css-truncate css-truncate-target">Had to invoke</span></p>
<p><span class="css-truncate css-truncate-target"> StackInterpreter initializeMiscConstants</span></p>
<p><span class="css-truncate css-truncate-target">Note that "StackInterpreter initialize" did _not_ set these.</span></p>
<p><br /></p>
<p><span class="css-truncate css-truncate-target">[2] I found/find pattern of "use every other float register" wacky. </span></p>
<p><span class="css-truncate css-truncate-target">Now I begin to see that this is to work around C typecast hoop jumps. So floatRegisters are now declared #float rather than #double. This changed the number of unit test failures from 7 to 3.</span></p>
<p><span class="css-truncate css-truncate-target">We probably need to (better) document this somewhere.</span></p>
<p><br /></p>
<p><span class="css-truncate css-truncate-target">On to those remaining unit tests, then I get to write some more! ;^)</span></p>
