mmatic05 added a comment.

Script (llvm-mca-pretty-printer.py) uses llvm-mca tool to print statistics in console for multiple files (when  diff option is used), or for single file (without diff option).
Options: -iterations, -mcpu, -mtriple or -useMca (specified relative path to llvm-mca) can also be used.

The script is used as follows:

  $  llvm-project/llvm/utils/llvm-mca-pretty-printer/llvm-mca-pretty-printer.py file1.s -useMca=build/bin/llvm-mca

  Input files:
  [f1]: file1.s
  
  ITERATIONS: 100
