[LLVMdev] generating a dynamic callgraph with llvm-prof

[Eric Soderstrom]

One can use "-insert-edge-profiling" with opt to collect general metrics
(frequency of function execution, frequency of basic block execution). But
I'd like to record all call information. So every time a function call is
made, I'd like to record [calling function name, callee function name]

Is this feasible with with llvm-prof and any of the existing profiling
options?
