# Use an empty profile to make non of the boot image be AOT compiled (for now).

# Note that we could use a previous profile but we will miss the opportunity to

# remove classes that are no longer in use.

# Ideally we would just generate an empty boot.art but we don't have the build

# support to separate the image from the compile code.
