The aarch32 port is merged up to jdk8u102-b14, whereas the jdk8u-dev tip is at jdk8u22-b01.

There is no formal mechanism. Every so often we will merge up to the latest tip although this has not been done for some months.

The C1 changes were only applied to jdk8u102-b14, so what you would need to do is

- diff the aarch32 tip against jdk8u102-b14
- apply those diff to jdk8u101-b13

This should be clean as we have kept changes outside the aarch32 specific code to a minimum.

All the best,
