[LLVMdev] Measure execution time of each basic block

[Vanderson Martins do Rosario]

Guys,

Someone have any idea how could I measure the execution time of each LLVM
basic block of a program?

I tried to use some profiling tools like gcov and perf, but as far as I
know they can only give me the frequency that each basic block is executed.

I was thinking about writing a pass to add PAPI instructions in each LLVM
basic block. Do you think is a good idea?

Thanks
