This seems to be the only occurrence of a #include in a .ad file. If it 
works I guess that is okay, but I don't know if it is intended to work.

  src/cpu/aarch64/vm/macroAssembler_aarch64.cpp

I was wondering if the include of the opto headers should be guarded by 
"#ifdef COMPILER2", but as the code that uses the definitions isn't also 
guarded then I guess not.

Copyright dates need updating before pushing.

Thanks,
David
