## 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
