## 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
