+AArch64 target
+--------------
+
+We've added support for AArch64, ARM's 64-bit architecture. Development is still
+in fairly early stages, but we expect successful compilation when:
+
+- compiling standard compliant C99 and C++03 with Clang;
+- using Linux as a target platform;
+- where code + static data doesn't exceed 4GB in size (heap allocated data has
+  no limitation).
+
+Some additional functionality is also implemented, notably DWARF debugging,
+GNU-style thread local storage and inline assembly.
