2025-05-20[libclc] Reorganize OpenCL builtins (#140557)Fraser Cormack
This commits moves all OpenCL builtins under a top-level 'opencl' directory, akin to how the CLC builtins are organized. This new structure aims to better convey the separation of the two layers and that 'CLC' is not a subset of OpenCL or a libclc target. In doing so this commit moves the location of the 'lib' directory to match CLC: libclc/generic/lib/ becomes libclc/opencl/lib/generic/. This allows us to remove some special casing in CMake and ensure a common directory structure. It also tries to better communicate that the OpenCL headers are libclc-specific OpenCL headers and should not be confused with or used as standard OpenCL headers. It does so by ensuring includes are of the form <clc/opencl/*>. It might be that we don't specifically need the libclc OpenCL headers and we simply could use clang's built-in declarations, but we can revisit that later. Aside from the code move, there is some code formatting and updating a couple of OpenCL builtin includes to use the readily available gentype helpers. This allows us to remove some '.inc' files.
2025-03-24[libclc] Add license headers to files missing them (#132239)Fraser Cormack
This commit bulk updates all '.h', '.cl', '.inc', and '.cpp' files to add any missing license headers. The remaining files are generally CMake, SOURCES, scripts, markdown, etc. There are still some '.ll' files which may benefit from a license header. I can't find an example of an LLVM IR file with a license header in the rest of LLVM, but unlike most other (sub)projects, libclc has examples of LLVM IR as source files, compiled and built into the library.
2013-07-08Add __CLC_ prefix to all macro definitions in headersTom Stellard
libclc was defining and undefing GENTYPE and several other macros with common names in its header files. This was preventing applications from defining macros with identical names as command line arguments to the compiler, because the definitions in the header files were masking the macros defined as compiler arguements.
