Changeset: 0a8b00b578cb Author: Goetz Lindenmaier Date: 2012-10-26 22:52 +0200 URL: http://hg.openjdk.java.net/ppc-aix-port/jdk7u/hotspot/rev/0a8b00b578cb Memory ordering: introduce functions to specify platform properties. Functions as store_store_is_ordered() say whether corresponding instructions on this platform can be reordered. Use these to decide whether to emit memory barriers. Replaces platform specific defines. For zero, conservative properties are assumed. ! src/os_cpu/aix_ppc/vm/orderAccess_aix_ppc.inline.hpp ! src/os_cpu/bsd_x86/vm/orderAccess_bsd_x86.inline.hpp ! src/os_cpu/bsd_zero/vm/orderAccess_bsd_zero.inline.hpp ! src/os_cpu/linux_ppc/vm/orderAccess_linux_ppc.inline.hpp ! src/os_cpu/linux_sparc/vm/orderAccess_linux_sparc.inline.hpp ! src/os_cpu/linux_x86/vm/orderAccess_linux_x86.inline.hpp ! src/os_cpu/linux_zero/vm/orderAccess_linux_zero.inline.hpp ! src/os_cpu/solaris_sparc/vm/orderAccess_solaris_sparc.inline.hpp ! src/os_cpu/solaris_x86/vm/orderAccess_solaris_x86.inline.hpp ! src/os_cpu/windows_x86/vm/orderAccess_windows_x86.inline.hpp ! src/share/vm/runtime/orderAccess.hpp
