Yumin,

Nice work!

Since you touch src/share/tools/hsdis/Makefile, can you fix the
following typo as well?

--- a/src/share/tools/hsdis/Makefile    Fri Aug 24 16:23:59 2012 -0700
+++ b/src/share/tools/hsdis/Makefile    Tue Aug 28 14:16:07 2012 +0400

-DLIB_EXT=\"$(LIB_EXT)\"

 TARGET_DIR     = build/$(OS)-$(JDKARCH)

Best regards,
