...they care about (e.g. port pressure or IPC), or generate an annotated trace. A similar functionality is provided in llvm-mca `XXView` implementations.

Hi all, At Sony we developed an LLVM based performance analysis tool named llvm-mca. We currently use it internally to statically measure the performance of code, and to help triage potential problems with target scheduling models. We decided to post this RFC because we are interested in the feedback from the community, and we also believe that other people might be interested in a tool like
