Description: C, C++ and Objective-C compiler (LLVM based), clang binary
Clang project is a C, C++, Objective C and Objective C++ front-end
for the LLVM compiler. Its goal is to offer a replacement to the GNU Compiler
Collection (GCC).
.
Clang implements all of the ISO C++ 1998, 11, 14 and 17 standards and also
provides most of the support of C++20.
.
This is a dependency package providing the default clang compiler.
