[AArch64] Allow SVE_AES instructions in streaming mode with SSVE_AES (#115526) In accordance with https://developer.arm.com/documentation/ddi0602/latest/, the following SVE2 instructions are available in streaming SVE mode if the target has FEAT_SSVE_AES - PMULLB, PMULLT (128-bit element) - AESE (vectors) - AESD (vectors) - AESMC - AESIMC This patch updates the predication of these instructions to reflect this architecture change. Note that the assembler predicates here always require at least one of sve2,ssve-aes due to the following condition on [FEAT_SVE_AES](https://developer.arm.com/documentation/109697/2024_09/Feature-descriptions/The-Armv9-0-architecture-extension?lang=en#md457-the-armv90-architecture-extension__feat_FEAT_SVE_AES) >If FEAT_SVE_AES is implemented, then FEAT_SVE2 or FEAT_SSVE_AES is implemented.
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
