Hi ZhengWei,

The *.ad files are part of the C2 JIT. This has not been written for aarch32.

What there is for aarch32 at the moment is a template interpreter. To build the template interpreter version use the option --with-jvm-variants=core on configure.

Work is underway to develop a C1 JIT for aarch32, however as far as I am aware there are no plans for a C2 JIT. Contributions welcome!

All the best,
Ed.
