aoqi@0: # The boot_cycle.sh script performs two complete image builds (no javadoc though....)
aoqi@0: # where the second build uses the first build as the boot jdk.
aoqi@0: #
aoqi@0: # This is useful to verify that the build is self hoisting and assists
aoqi@0: # in flushing out bugs. You can follow up with compare_objects.sh to check
aoqi@0: # that the two boot_cycle_?/images/j2sdk are identical. They should be.
aoqi@0: #
aoqi@0: # Usage:
aoqi@0: # Specify the configure arguments to boot_cycle.sh, for example:
aoqi@0: #
aoqi@0: #    sh common/bin/boot_cycle.sh --enable-debug --with-jvm-variants=server
aoqi@0: #
aoqi@0: # The same arguments will be used for both builds, except of course --with-boot-jdk
aoqi@0: # that will be adjusted to boot_cycle_1 for the second build.
