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.
