 Changes to the ARM Backend
 --------------------------
+* The `+nosimd` attribute is now fully supported. Previously, this had no effect when being used with
+AArch32 targets, however will now disable NEON instructions being generated. The `simd` is also now
+printed when the `--print-supported-extensions` option is used..
