This patch introduces support for Cortex-A75 and Cortex-A55, Arm's latest big.LITTLE A-class cores. They implement the ARMv8.2-A architecture, including the cryptography and RAS extensions, plus the optional dot product extension. They also implement the RCpc AArch64 extension from ARMv8.3-A. Cortex-A75: https://developer.arm.com/products/processors/cortex-a/cortex-a75 Cortex-A55: https://developer.arm.com/products/processors/cortex-a/cortex-a55 Differential Revision: https://reviews.llvm.org/D36667 llvm-svn: 311316
