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: DISABLEDWARNINGSclang := deprecated-declarations I assume we turn "deprecated-declarations” into “-Wdeprecated-declarations” flag that then gets passed to the compiler? Yes, (to be more precise -Wno-deprecated-declarations) this is the preferred way of disabling warnings in the build.

cheers

This patch changes the values for the macosx version min and max settings from 10.7 to 10.9. 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 This change is necessary to keep up with newer toolchain versions on Macosx where using the old and no longer maintained libstdc++ has been deprecated.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. The switch has been tested for both Hotspot and client. The switch triggered some new deprecation warnings which have been silenced and followup bugs have been filed on the concerned team.
