1.28 +# The boot_cycle.sh script performs two complete image builds (no javadoc though....)
1.29 +# where the second build uses the first build as the boot jdk.
1.30 +#
1.31 +# This is useful to verify that the build is self hoisting and assists
1.32 +# in flushing out bugs. You can follow up with compare_objects.sh to check
1.33 +# that the two boot_cycle_?/images/j2sdk are identical. They should be.
1.34 +#
1.35 +# Usage:
1.36 +# Specify the configure arguments to boot_cycle.sh, for example:
1.37 +#
1.38 +# sh common/bin/boot_cycle.sh --enable-debug --with-jvm-variants=server
1.39 +#
1.40 +# The same arguments will be used for both builds, except of course --with-boot-jdk
1.41 +# that will be adjusted to boot_cycle_1 for the second build.
