6994628: G1: Test gc/gctests/FinalizeTest05 fails (one live object is finalized) Summary: The Solaris Studio 12 update 1 C++ compiler was incorrectly re-ordering the reads of an object's mark word in oopDesc::forward_to_atomic(). This opened a small window where one thread could execute the successful CAS path even though another thread had already successfully forwarded the object. This could result in an object being copied twice. The code in oopDesc::forward_to_atomic() was changed to read the mark word once. Reviewed-by: ysr, tonyp

# This makefile creates a build tree and lights off a build.
# You can go back into the build tree and perform rebuilds or
# incremental builds as desired. Be sure to reestablish
# environment variable settings for LD_LIBRARY_PATH and JAVA_HOME.

# The make process now relies on java and javac. These can be
# specified either implicitly on the PATH, by setting the
# (JDK-inherited) ALT_BOOTDIR environment variable to full path to a
# JDK in which bin/java and bin/javac are present and working (e.g.,
# /usr/local/java/jdk1.3/solaris), or via the (JDK-inherited)
# default BOOTDIR path value. Note that one of ALT_BOOTDIR
# or BOOTDIR has to be set. We do *not* search javac, javah, rmic etc.
# from the PATH.

# Along with VM, Serviceability Agent (SA) is built for SA/JDI binding.
# JDI binding on SA produces two binaries:
#  1. sa-jdi.jar       - This is build before building libjvm[_g].so
#                        Please refer to ./makefiles/sa.make
#  2. libsaproc[_g].so - Native library for SA - This is built after
#                        libjsig[_g].so (signal interposition library)
#                        Please refer to ./makefiles/vm.make
# If $(GAMMADIR)/agent dir is not present, SA components are not built.

# The following renders pathnames in generated Makefiles valid on
# machines other than the machine containing the build tree.
#
# For example, let's say my build tree lives on /files12 on
# exact.east.sun.com.  This logic will cause GAMMADIR to begin with
# /net/exact/files12/...
#
# We only do this on SunOS variants, for a couple of reasons:
#  * It is extremely rare that source trees exist on other systems
#  * It has been claimed that the Linux automounter is flakey, so
#    changing GAMMADIR in a way that exercises the automounter could
#    prove to be a source of unreliability in the build process.
# Obviously, this Makefile is only relevant on SunOS boxes to begin
# with, but the SunOS conditionalization will make it easier to
# combine Makefiles in the future (assuming we ever do that).
