[RFC] Generate Debug Information for Labels in Function
Hi all,
I am sorry that I didn’t carefully think about how to handle labels in
inlined function.
Today, I did some simple experiments and found that some basic block
may be removed in CFGSimplifyPass and the attached metadata will be
eliminated. So, if the optimization is turned on, label metadata will
disappear. However, intrinsic will keep existing in the function if we
handle it correctly. So, if we take care about optimization and
inlining, to keep label metadata through intrinsic could be...
