| ## This script checks that perf2bolt is reading pre-aggregated perf information |
| ## correctly for a simple example. The perf.data of this example was generated |
| ## with the following command: |
| ## |
| ## $ perf record -j any,u -e branch -o perf.data -- ./blarge |
| ## |
| ## blarge is the binary for "basicmath large inputs" taken from Mibench. |
| |
| ## Currently failing in MacOS / generating different hash for usqrt |
| REQUIRES: system-linux |
