This is a new draft of D28234. I previously did the unorthodox thing of pushing to it when I wasn't the original author, but since this version - Uses `GNUInstallDirs`, rather than mimics it, as the original author was hesitant to do but others requested. - Is much broader, effecting many more projects than LLVM itself. I figured it was time to make a new revision. I am using this patch (and many back-ports) as the basis of https://github.com/NixOS/nixpkgs/pull/111487 for my distro (NixOS). It looked like people were generally on board in D28234, but I make note of this here in case extra motivation is useful. --- As pointed out in the original issue, a central tension is that LLVM already has some partial support for these sorts of things. For example `LLVM_LIBDIR_SUFFIX`, or `COMPILER_RT_INSTALL_PATH`. Because it's not quite clear yet what to do about those, we are holding off on changing libdirs and `compiler-rt`. for this initial PR. --- On the advice of @lebedev.ri, I am splitting this up a bit per subproject, starting with LLVM. To allow it to be more easily reviewed. This and the subsequent patch must be landed together, as this will not build alone. But the rest can be landed on their own.

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.
