John Brawn cfeb25cd7e [lld][AArch64] Add support for GCS (#90732)
This adds the -z gcs and -z gcs-report options, which behave similarly
to -z shtk and -z cet-report, except that -z gcs accepts a parameter:
* -z gcs=implicit is the default behaviour, where the GCS bit is
inferred from the input objects.
 * -z gcs=never clears the GCS bit, ignoring the input objects.
 * -z gcs=always sets the GCS bit, ignoring the input objects.

This is so that there's a means of explicitly disabling GCS even when
all input objects have the GCS bit set.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

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.
