font-family:Arial'>I have a very simple kernel that exposes a bug in the
backend I am working on and I cannot figure out how to fix the problem. I’ve
narrowed down the issue to be with dynamic stack allocation. The problem I am
having is that if I declare a variable inside of the loop, the code that my
backend generates produces incorrect results; however, if I move this
declaration outside of the loop the generated code works correctly.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My backend does not have a stack pointer and no memory
allocations. So I really can’t use any of the approaches of the currently
implemented backends. What I would like to do is to just turn all of the stack
allocations into register moves to virtual registers. Any tips or hints would
be greatly appreciated.<o:p></o:p></span></font></p>
