RFR 8150388: Remove SPARC 32-bit support

[Gerald Thornbrugh]

Hi George,

Wow, this is bigger than I thought it would be.

A couple of questions:

I assume you will update the copyright years before you putback?

src <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/>/os_cpu <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/>/solaris_sparc <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/solaris_sparc/>/vm <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/solaris_sparc/vm/>/atomic_solaris_sparc.hpp <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/solaris_sparc/vm/atomic_solaris_sparc.hpp>

Line 245, you can probably remove the " || defined(_LP64)”
Line 372, you can probably remove the "_LP64 ||”

Is there a reason you did not include prefetch_solaris_sparc.inline.hpp in your changes?

src <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/>/os_cpu <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/>/solaris_sparc <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/solaris_sparc/>/vm <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/solaris_sparc/vm/>/prefetch_solaris_sparc.inline.hpp <https://grok.cz.oracle.com/source/xref/jdk9/hotspot/src/os_cpu/solaris_sparc/vm/prefetch_solaris_sparc.inline.hpp>

Line 30, 58 and 63, you can probably remove the references to _LP64

Is there a plan to remove the SPARC 32 bit support from the makefiles and build configuration files?

Thanks!

Jerry
