   I can think of two ways extra spilling could occur.   
      
   Firstly - in a more complex example, your spill code might not be   
   optimally placed. In particular your spiller might not be   
   sophisticated enough to do live range splitting, and put the spill   
   code in the same place that the register save and restores would have   
   been originally.   
      
   Secondly - the compiler might (and probably should) do extra optimisation   
   passes after inlining. This could lead to further redundancy elimination   
   due to the improved information, which would then lead to extra register   
   pressure.
