Hi, I'd like a simple and fast way to collect the number of times each Instruction was executed in a given run of the application. As far as I can tell, there are a number of approaches I can take: - Use PIN. This would require using DWARF debug info and Instruction debug info to attempt to map instructions in the binary to instructions in the bitcode; not 100% sure how accurate this will
