[FMV][AArch64] Unify aes with pmull and sve2-aes with sve2-pmull128. (#111673) According to the Arm Architecture Reference Manual for A-profile architecture you can't have one feature without having the other: ID_AA64ZFR0_EL1.AES, bits [7:4] > FEAT_SVE_AES implements the functionality identified by the value 0b0001. > FEAT_SVE_PMULL128 implements the functionality identified by the value 0b0010. > The permitted values are 0b0000 and 0b0010. (The following was removed from the latest release of the specification, but it appears to be a mistake that was not intended to relax the architecture constraints. The discrepancy has been reported) ID_AA64ISAR0_EL1.AES, bits [7:4] > FEAT_AES implements the functionality identified by the value 0b0001. > FEAT_PMULL implements the functionality identified by the value 0b0010. > From Armv8, the permitted values are 0b0000 and 0b0010.

Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
