[Flang] [OpenMP] [Semantics] [MLIR] [Lowering] Add lowering support for IS_DEVICE_PTR and HAS_DEVICE_ADDR clauses on OMP TARGET directive. (#74187) Added lowering support for IS_DEVICE_PTR and HAS_DEVICE_ADDR clauses for OMP TARGET directive and added related tests for these changes. IS_DEVICE_PTR and HAS_DEVICE_ADDR clauses apply to OMP TARGET directive OpenMP spec states `The **is_device_ptr** clause indicates that its list items are device pointers.` `The **has_device_addr** clause indicates that its list items already have device addresses and therefore they may be directly accessed from a target device.` Whereas USE_DEVICE_PTR and USE_DEVICE_ADDR clauses apply to OMP TARGET DATA directive and OpenMP spec for them states `Each list item in the **use_device_ptr** clause results in a new list item that is a device pointer that refers to a device address` `Each list item in a **use_device_addr** clause that is present in the device data environment is treated as if it is implicitly mapped by a map clause on the construct with a map-type of alloc`
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.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
