<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I don’t believe that the current implementation sets the permissions on JITed memory as you might wish. Namely, I think executable memory may be left writeable
and data memory may be executable. The current interface is also somewhat limited. Basically, you pass a Module to the constructor, it JITs that Module immediately and then you can get the address of individual functions to execute them. What is there works
though.<o:p></o:p></span></p>
