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