Android’s GCC 4.9 has been deprecated in favor of Clang, and will be removed from Android in January 2020 as per the below timeline.
Please report bugs and feature requests to firstname.lastname@example.org.
Prebuilts of Clang can be found for Linux x86_64 hosts:
Prebuilts of newer versions of Clang will be made available regularly. These prebuilts exist only to accelerate Clang’s release cycle and contain no out of tree patches, only reverts and cherry-picks from upstream.
Vendors looking to keep GCC from being removed may pin the revision of Android GCC prebuilts, but should not expect Google to maintain GCC support going forward.
