+* Support for targeting Armv2, Armv2A, Armv3 and Armv3M has been removed.
   LLVM did not, and was not ever likely to generate correct code for those
   architecture versions so their presence was misleading.
+* Added full LLD support for Armv4 and Armv4T by adding support for Armv4 and

+  instructions for either Arv4 or Armv4T.
+* Added compiler-rt builtins support for Armv4T, Armv5TE and Armv6.
