RFR: JDK-8196724: Change macosx deployment target to 10.9

[Gerard Ziemski]

hi Erik,

Thanks for doing this.

I like how you are using a narrow mechanism to turn off only those warnings that come up due to deprecated APIs.

Just a quick verification question (not very familiar with the makefiles), in line like this:

DISABLED_WARNINGS_clang := deprecated-declarations

I assume we turn "deprecated-declarations” into “-Wdeprecated-declarations” flag that then gets passed to the compiler?


cheers

It also changes the stdlib from libstdc++ to libc++ (explicitly for Hotspot and implicitly everywhere else). This change is necessary to keep up with newer toolchain versions on Macosx where using the old and no longer maintained libstdc++ has been deprecated. This is done in preparation for bumping the preferred Xcode version used for builds at Oracle.
