[HLSL][RootSignature] Add `fdx-rootsignature-version` option to specify root signature version (#144813) This pr provides the ability to specify the root signature version as a compiler option and to retain this in the root signature decl. It also updates the methods to serialize the version when dumping the declaration and to output the version when generating the metadata. - Update `DXContainer.hI` to define the root signature versions - Update `Options.td` and `LangOpts.h` to define the `fdx-rootsignature-version` compiler option - Update `Options.td` to provide an alias `force-rootsig-ver` in clang-dxc - Update `Decl.[h|cpp]` and `SeamHLSL.cpp` so that `RootSignatureDecl` will retain its version type - Updates `CGHLSLRuntime.cpp` to generate the extra metadata field - Add tests to illustrate Resolves https://github.com/llvm/llvm-project/issues/126557. Note: this does not implement validation based on versioning. https://github.com/llvm/llvm-project/issues/129940 is required to retrieve the version and use it for validations.
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.
