Hi
   if I have a function that has an formal argument assigned to  say
register R0 and I have the following code fragment as my first basic
block


BB#0
   %reg100023<dead> =   // for some reason could not be removed
      ...
                   = R0 <kill>


What prevents R0 from being allocated to %reg100023


thanks
shrey
