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. |
