[LLVMdev] line number information

[Jim Laskey]

John,

If you look at the stoppoint calls you'll see that you can find the  
line number and if you follow the compile unit argument on the call  
you will find the file.  The byte codes that follow the call would  
have been generated by the code on that source line.
