[mlir][mlir-vulkan-runner] Move part of device pass pipeline to mlir-opt (#119372) Adds a new mlir-opt test-only pass, -test-vulkan-runner-pipeline, which runs a set of passes needed for mlir-vulkan-runner, and removes them from the runner. The tests are changed to invoke mlir-opt with this flag before invoking the runner. The passes moved are ones concerned with lowering of the device code prior to serialization to SPIR-V. This is an incremental step towards moving the entire pipeline to mlir-opt, to align with other runners (see #73457).
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.
