interested in the library version (https://reviews.llvm.org/D50929?id=162210
<https://reviews.llvm.org/D50929?id=162210>) but I have troubles
understanding how to use it. Could you please point me to some documentations or
(better) some code examples if any?

Reading the documentation (https://llvm.org/docs/CommandGuide/llvm-mca.html
<https://llvm.org/docs/CommandGuide/llvm-mca.html>) it also seems that
llvm-mca does not take into account the cache hierarchy. Does this mean that the
tool assumes all the loads/stores hit the L1 cache?

Looking forward to hearing from you.
Best regards,

Lorenzo Chelini.
