Reviewers of #89153 suggested to break up the patch into per-subproject patches. This is the libclc part. See #89153 for the entire series and motivation. Update the folder titles for targets in the monorepository that have not seen taken care of for some time. These are the folders that targets are organized in Visual Studio and XCode (`set_property(TARGET <target> PROPERTY FOLDER "<title>")`) when using the respective CMake's IDE generator. * Ensure that every target is in a folder * Use a folder hierarchy with each LLVM subproject as a top-level folder * Use consistent folder names between subprojects * When using target-creating functions from AddLLVM.cmake, automatically deduce the folder. This reduces the number of `set_property`/`set_target_property`, but are still necessary when `add_custom_target`, `add_executable`, `add_library`, etc. are used. A LLVM_SUBPROJECT_TITLE definition is used for that in each subproject's root CMakeLists.txt.
libclc ------ libclc is an open source, BSD licensed implementation of the library requirements of the OpenCL C programming language, as specified by the OpenCL 1.1 Specification. The following sections of the specification impose library requirements: * 6.1: Supported Data Types * 6.2.3: Explicit Conversions * 6.2.4.2: Reinterpreting Types Using as_type() and as_typen() * 6.9: Preprocessor Directives and Macros * 6.11: Built-in Functions * 9.3: Double Precision Floating-Point * 9.4: 64-bit Atomics * 9.5: Writing to 3D image memory objects * 9.6: Half Precision Floating-Point libclc is intended to be used with the Clang compiler's OpenCL frontend. libclc is designed to be portable and extensible. To this end, it provides generic implementations of most library requirements, allowing the target to override the generic implementation at the granularity of individual functions. libclc currently only supports the PTX target, but support for more targets is welcome.
