What kind of compiler is clang for llvm?


Asked by Chana Howell on Nov 30, 2021 FAQ



The Clang project provides a language front-end and tooling infrastructure for languages in the C language family (C, C++, Objective C/C++, OpenCL, CUDA, and RenderScript) for the LLVM project. Both a GCC-compatible compiler driver ( clang) and an MSVC-compatible compiler driver ( clang-cl.exe) are provided.
Also Know,
Clang is the front end of LLVM tool chain ( "clang" C Language Family Frontend for LLVM ). Every Compiler has three parts . 1. Front end ( lexical analysis, parsing ) 2. Optimizer ( Optimizing abstract syntax tree ) 3. Back end ( machine code generation )
Also, Clang uses the LLVM compiler as its back end and it has been included in the release of the LLVM since the LLVM 2.6. Clang is also built to be a drop-in replacement for GCC command. In its design, the Clang compiler has been constructed to work very similarly to GCC to ensure that portability is maximized.
Thereof,
However, LLVM and the open source C-language compiler built on top of it (Clang) do not get a lot of attention in the embedded world. In this article, I hope I can convince you that adding a Clang build target to your project can be a relatively simple and useful endeavor.
Subsequently,
The roster of languages making use of LLVM has many familiar names. Apple’s Swift language uses LLVM as its compiler framework, and Rust uses LLVM as a core component of its tool chain. Also, many compilers have an LLVM edition, such as Clang, the C/C++ compiler (this the name, “C-lang”), itself a project closely allied with LLVM.
