hello everyone,

I few days ago I had some code (for the PyPy project) that llc - 
march=c converted to a switch statement and gcc compiled that nicely  
to a jumptable in the .s file. Now I try to reproduce when directly  
going from a .ll to a .s file. But I now see a long list of compare  
and jumps instead of the jumptable. Is there a transformation that  
does this if->switch(ing) or is that in the part of llc that  
generates the c file?
