Add in SVE/SVE2/MOPS features for aarch64 cpus. These features may be interesting for future memory/math routines. SVE/SVE2 are now being accepted in more implementations: ``` ❯ echo | clang-21 -dM -E - -march=native | grep -i ARM_FEAT #define __ARM_FEATURE_ATOMICS 1 #define __ARM_FEATURE_BF16 1 #define __ARM_FEATURE_BF16_SCALAR_ARITHMETIC 1 #define __ARM_FEATURE_BF16_VECTOR_ARITHMETIC 1 #define __ARM_FEATURE_BTI 1 #define __ARM_FEATURE_CLZ 1 #define __ARM_FEATURE_COMPLEX 1 #define __ARM_FEATURE_CRC32 1 #define __ARM_FEATURE_DIRECTED_ROUNDING 1 #define __ARM_FEATURE_DIV 1 #define __ARM_FEATURE_DOTPROD 1 #define __ARM_FEATURE_FMA 1 #define __ARM_FEATURE_FP16_SCALAR_ARITHMETIC 1 #define __ARM_FEATURE_FP16_VECTOR_ARITHMETIC 1 #define __ARM_FEATURE_FRINT 1 #define __ARM_FEATURE_IDIV 1 #define __ARM_FEATURE_JCVT 1 #define __ARM_FEATURE_LDREX 0xF #define __ARM_FEATURE_MATMUL_INT8 1 #define __ARM_FEATURE_NUMERIC_MAXMIN 1 #define __ARM_FEATURE_PAUTH 1 #define __ARM_FEATURE_QRDMX 1 #define __ARM_FEATURE_RCPC 1 #define __ARM_FEATURE_SVE 1 #define __ARM_FEATURE_SVE2 1 #define __ARM_FEATURE_SVE_BF16 1 #define __ARM_FEATURE_SVE_MATMUL_INT8 1 #define __ARM_FEATURE_SVE_VECTOR_OPERATORS 2 #define __ARM_FEATURE_UNALIGNED 1 ``` MOPS is another set of extension for string operations, but may not be generally available for now: ``` ❯ echo | clang-21 -dM -E - -march=armv9.2a+mops | grep -i MOPS #define __ARM_FEATURE_MOPS 1 ```
The LLVM Compiler Infrastructure
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.
Getting the Source Code and Building LLVM
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.
Getting in touch
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.
