[PATCH, BINUTILS, AARCH64, 6/9] Add Random number instructions
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/exploration-tools)
The encodings can be found in the System Register XML.
This patch adds the following:
MSR Xn, RNDR
MSR Xn, RNDRRS
These are optional instructions in ARMv8.5-A and hence the new
+rng is added.
