Clang and LLVM. What is it?

Question

C++ / C#

Hello! After a little googling, I came to the conclusion that Clang is a code generator that receives a cpp file as input, and we have some kind of intermediate code as output. But LLVM can already execute or compile this code.
But I am tormented by vague doubts! Help, please, to understand!

Answer 1

Yes you are right. Clang is a frontend that generates an intermediate representation. LLVM takes an intermediate representation (regardless of the language in which the original code was written), optimizes and generates a binary file.
GCC uses a similar system (before clang, LLVM generally accepted IF from GCC). This allows you to have one backend for multiple languages. In fact, only the parser has to be developed.
