+
+Prebuilts of Clang can be found for Linux x86_64 hosts:
+
+https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+/master
+
+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.
