## Purpose This patch is one in a series of code-mods that annotate LLVM’s public interface for export. This patch annotates the `llvm/Target` library. These annotations currently have no meaningful impact on the LLVM build; however, they are a prerequisite to support an LLVM Windows DLL (shared library) build. ## Background This effort is tracked in #109483. Additional context is provided in [this discourse](https://discourse.llvm.org/t/psa-annotating-llvm-public-interface/85307), and documentation for `LLVM_ABI` and related annotations is found in the LLVM repo [here](https://github.com/llvm/llvm-project/blob/main/llvm/docs/InterfaceExportAnnotations.rst). A sub-set of these changes were generated automatically using the [Interface Definition Scanner (IDS)](https://github.com/compnerd/ids) tool, followed formatting with `git clang-format`. The bulk of this change is manual additions of `LLVM_ABI` to `LLVMInitializeX` functions defined in .cpp files under llvm/lib/Target. Adding `LLVM_ABI` to the function implementation is required here because they do not `#include "llvm/Support/TargetSelect.h"`, which contains the declarations for this functions and was already updated with `LLVM_ABI` in a previous patch. I considered patching these files with `#include "llvm/Support/TargetSelect.h"` instead, but since TargetSelect.h is a large file with a bunch of preprocessor x-macro stuff in it I was concerned it would unnecessarily impact compile times. In addition, a number of unit tests under llvm/unittests/Target required additional dependencies to make them build correctly against the LLVM DLL on Windows using MSVC. ## Validation Local builds and tests to validate cross-platform compatibility. This included llvm, clang, and lldb on the following configurations: - Windows with MSVC - Windows with Clang - Linux with GCC - Linux with Clang - Darwin with Clang
