Matt Arsenault b03b97b828 clang/AMDGPU: Require 16-bit-insts for half typed buffer format builtins
Typed buffer format load/store operations with 16-bit elements require
d16 support which was introduced in gfx8. These builtins previously had
no required features at all, so they were accepted (and then crashed the
backend) on targets without 16-bit support.

Diagnose these in Sema, parallel to the image builtins. The manual
verification here suprised me. The automatic builtin feature verification
is enforced in codegen, which seems like a layering violation which
should be fixed.

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.
