-   DETERMINISTIC_CHECKPOINTS USAGE TIPS
-
-  • Set SPEC CPU 2006 source code: edit  config.nix :  spec2006_path = [...]
-  • Set input size: edit  config.nix :  size = xxx  (default input is ref)
-  • Change other configs in  config.nix
-  • Generate the checkpoints of all testCases into  result/ :  nom-build -A checkpoints
-  • Generate the checkpoints of a specific testCase into  result/ :  nom-build -A checkpoints.<testCase>
-    • E.g.:  nom-build -A checkpoints.403_gcc
-  • Running nom-build without parameters will generate results-* directory containing all intermediate build results, symlinked to the corresponding /nix/store/....nix. You can then use dump_result.py to read the log files within and obtain the dynamic instruction count of the program.
-    • E.g.:  nom-build
