URL: https://github.com/llvm/llvm-project/commit/e47027d091deb4a0774eab911411a27092a60916 DIFF: https://github.com/llvm/llvm-project/commit/e47027d091deb4a0774eab911411a27092a60916.diff LOG: [OpenCL] Use DW_LANG_OpenCL language tag for OpenCL C Note regarding C++ for OpenCL: When compiling C++ for OpenCL, DW_LANG_C_plus_plus* is emitted. There is no DWARF language code defined for C++ for OpenCL as of yet, but DWARF issue 210514.1 has been raised to request one. In the mean time, continuing to emit DW_LANG_C_plus_plus* for C++ for OpenCL allows the potential to distinguish between C++ for OpenCL and OpenCL C in !DICompileUnit nodes, whereas using DW_LANG_OpenCL for C++ for OpenCL would prevent this. This change therefore leaves C++ for OpenCL as-is.
