RFR: 8019470 "Changes needed to compile JDK8 on MacOS with clang compiler"

[Helio Frota]

Hi great all,

I found this article:
http://www.phoronix.com/scan.php?page=article&item=llvm_clang33_3way&num=2
http://www.phoronix.com/scan.php?page=article&item=llvm_clang33_3way&num=3
http://www.phoronix.com/scan.php?page=article&item=llvm_clang33_3way&num=4

And GCC wins all on performance issues.

Best regards,
Helio
