Hi Lois,

Is this still needed:

 142     PCH_FLAG/unsafe.o = $(PCH_FLAG/NO_PCH)

given you no longer use -O0 ?

Thanks,
David

Bug:
     bug link at https://bugs.openjdk.java.net/browse/JDK-8022407

Summary of fix:

     The JDK 8 build on MacOS, when built with the Xcode 4.6.2 clang++
compiler, exhibited a compiler
     optimization issue when prims/unsafe.cpp was compiled at the
default -Os level. As a work around
     fix, knock the optimization level down down to -O1.

Tests: MacOS: built fastdebug & product images using clang++ (ran JTREG
& vm.quick.testlist)
           built using llvm-g++ to verifyprims/unsafe.cpp remained
compiled at -Os

Thank you, Lois
