fixes #159438 This patch adds `MatrixElementExpr`, a new AST node for HLSL matrix element and swizzle access (e.g. M._m00, M._11_22_33). It introduces a shared `ElementAccessExprBase` used by both matrix and vector swizzle expressions, updates Sema to parse and validate zero-based and one-based accessors, detects duplicates for l-value checks, and emits improved diagnostics. CodeGen is updated to lower scalar and multi-element accesses consistently, and full AST serialization, dumping, and tooling support is included. This implementation reflects the updated [RFC](https://github.com/llvm/wg-hlsl/pull/357/files) for HLSL matrix accessor semantics.
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.
