I can't see why it would. x86 & amd64 already work for both Zero and non-Zero builds.

As you can see in the cleanup I just pushed:

http://icedtea.classpath.org/hg/icedtea7-forest/jdk/rev/b7b1a66665ce

Most of the changes are duplicated by Zero AArch64 support; the Platform.gmk & SoundDefs.gmk
changes were already present so I've removed them and also reordered things so they are again
listed alphabetically.

The only changes specific to the AArch64 port are the new jvm.cfg and mapfile, as well as
the CFLAGS (Zero sets its own):

ifeq ($(ZERO_BUILD), true)
  CFLAGS_REQUIRED       =  $(ZERO_ARCHFLAG)
  ifeq ($(ZERO_ENDIANNESS), little)
    CFLAGS_REQUIRED     += -D_LITTLE_ENDIAN
  endif
  LDFLAGS_COMMON        += $(ZERO_ARCHFLAG)
else
  CFLAGS_REQUIRED       =  $(CFLAGS_REQUIRED_$(ARCH))
  LDFLAGS_COMMON        += $(LDFLAGS_COMMON_$(ARCH))
endif

So I don't see how the AArch64 port changes will have any effect on Zero.
