| 29 | # Runs d8 with the given arguments on the device under 'perf' and |
| 30 | # processes the profiler trace and v8 logs using ll_prof.py. |
| 31 | # |
| 32 | # Usage: |
| 33 | # > ./tools/android-ll-prof.sh (debug|release) "args to d8" "args to ll_prof.py" |
| 34 | # |
| 35 | # The script creates deploy directory deploy/data/local/tmp/v8, copies there |
| 36 | # the d8 binary either from out/android_arm.release or out/android_arm.debug, |
| 37 | # and then sync the deploy directory with /data/local/tmp/v8 on the device. |
| 38 | # You can put JS files in the deploy directory before running the script. |
| 39 | # Note: $ANDROID_NDK_ROOT must be set. |
