IACA is awesome to understand the behaviour of your own hot loops. Sadly it only works on Intel. Luckily LLVM has recently merged llvm-mca [1] (machine-code analyser) which hopefully will in time bring all the features of IACA and more to other platforms as well. I am working on making these tools easily accessible from Julia [2] and one of the things missing from llvm-mca is the ability to mark a region of assembly code to be analysed instead of analysing the entire provided assembly.
