25 # The boot_cycle.sh script performs two complete image builds (no javadoc though....)
26 # where the second build uses the first build as the boot jdk.
27 #
28 # This is useful to verify that the build is self hoisting and assists
29 # in flushing out bugs. You can follow up with compare_objects.sh to check
30 # that the two boot_cycle_?/images/j2sdk are identical. They should be.
31 #
32 # Usage:
33 # Specify the configure arguments to boot_cycle.sh, for example:
34 #
35 # sh common/bin/boot_cycle.sh --enable-debug --with-jvm-variants=server
36 #
37 # The same arguments will be used for both builds, except of course --with-boot-jdk
38 # that will be adjusted to boot_cycle_1 for the second build.
