## Purpose This patch is one in a series of code-mods that annotate LLVM’s public interface for export. This patch annotates the `llvm/Transforms` 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). The bulk 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 following manual adjustments were also applied after running IDS on Linux: - Removed a redundant `operator<<` from Attributor.h. IDS only auto-annotates the 1st declaration, and the 2nd declaration being un-annotated resulted in an "inconsistent linkage" error on Windows when building LLVM as a DLL. - `#include` the `VirtualFileSystem.h` in PGOInstrumentation.h and remove the local declaration of the `vfs::FileSystem` class. This is required because exporting the `PGOInstrumentationUse` constructor requires the class be fully defined because it is used by an argument. - Add #include "llvm/Support/Compiler.h" to files where it was not auto-added by IDS due to no pre-existing block of include statements. - Add `LLVM_TEMPLATE_ABI` and `LLVM_EXPORT_TEMPLATE` to exported instantiated templates. ## 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
