Hi, Just for clarification (llvm 13.0 on openSuse TW): is llvm-profdata merge ... meant to be capable of producing merged data for runs of different executables, which use the same shared libraries ? E.g. I have libA and libB, and exe1, exe2 - both exe link against libA and libB Can I run both exe and then merge ALL the resulting raw data ? (I'm just thinking about e.g. the main() and other functions, which exist twice) -- Best regards/Schöne Grüße Martin A: Because it breaks the logical sequence of discussion Q: Why is top posting bad?
