+clang
+________________________________________________________________________________
+
+Clang is a compiler front end for the C, C++, Objective-C and Objective-C++
+programming languages, as well as the OpenMP, OpenCL, RenderScript, CUDA and
+HIP frameworks. It uses the LLVM compiler infrastructure as its back end and has
+been part of the LLVM release cycle since LLVM 2.6.
+
+It is designed to act as a drop-in replacement for the GNU Compiler Collection
+(GCC), supporting most of its compilation flags and unofficial language
+extensions. Its contributors include Apple, Microsoft, Google, ARM, Sony,
+Intel and Advanced Micro Devices (AMD). [0]
