[builtins] Fix CPU feature detection for FreeBSD on AArch64 (#76532) [builtins] Fix CPU feature detection for FreeBSD on AArch64 This is a follow-up to #75635 which broke the build for FreeBSD on AArch64: ``` compiler-rt/lib/builtins/cpu_model/aarch64/lse_atomics/freebsd.inc:3:16: error: call to undeclared function 'elf_aux_info'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 3 | int result = elf_aux_info(AT_HWCAP, &hwcap, sizeof hwcap); | ^ ``` Using `elf_aux_info()` requires including `<sys/auxv.h>` first. To prevent redeclaration issues with `hwcap.inc` attempting to define `HWCAP_xxx` macros before `<sys/auxv.h>` does so, include `<sys/auxv.h>` before any of the `.inc` files on FreeBSD.
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.
