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