[llvm-dev] How jump－table representated in DAG

[yao via llvm-dev]

Hi, all


I am  interested in how jump-table representated in DAG.
I find the method  visitJumpTable will Emit JumpTable node in the current MBB.
 visitJumpTableHeader - This function emits necessary code to produce index in the JumpTable from switch case.
but how  switch case emits? 


I would like to make this clearly.


Thanks,
yaoxiao
