Hello Everybody,


Please review v.05 of adding AArch64 support to lworld branch

http://cr.openjdk.java.net/~dsamersoff/valhalla_lworld_aarch64/webrev.05/

What was done:

  Implemented Valhalla support for aarch64.

  Support for ValueTypePassFieldsAsArgs and ValueTypeReturnedAsFields
  is not completed and is not included into this webrev
  to reduce review and rebasing efforts.

Testing:

   All tests in runtime/valhalla/valuetypes and in
compiler/valhalla/valuetypes/ are passed

   compiler/valhalla/valuetypes/TestMethodHandles.java
   compiler/valhalla/valuetypes/TestBasicFunctionality.java

   are passed after manually tweaking of output patterns, I have not
found a way to support both x86 and aarch64, so these tests remain
unchanged and run on x64 only.


-Dmitry
