Jul 19, 2014 · Clang is a front-end for LLVM that processes C-family languages: C, C++, Objective C, Objective C++. Clang converts C/C++/etc to LLVM IR, LLVM performs optimizations on the IR, and the LLVM x86 backend writes out x86 machine code for execution. Despite the name, LLVM is not a Virtual Machine in the traditional sense - it is a computation model ...
In conclusion, both GCC and LLVM are excellent compilers with their own unique strengths and weaknesses. GCC is known for its speed and stability, while LLVM is praised for its advanced optimization techniques and flexibility. Ultimately, the choice between GCC and LLVM depends on your specific needs and preferences as a developer. It is ...
Dec 20, 2019 · Performance Tests by a Compiler Expert. These tests and analyzes were done by Mike Kinghan a Oxford Software Engineer. The tests were performed on different architectures and also on different amounts of processor cores. With versions GCC 4.7.2 and Clang 3.2. It can be noted that Clang (LLVM) outperforms larger cores and GCC for smaller and/or ...
Aug 28, 2019 · Background. Visual C++, GNU Compiler Collection (GCC), and Clang/Low Level Virtual Machine (LLVM) are three mainstream C/C++ compilers in the industry. Visual C++ provides graphical user interfaces (GUIs) and is easy to debug, but it is not suitable for Linux platforms. Therefore, this document mainly compares GCC with Clang/LLVM.

License for GCC runtime libraries adds another layer of restrictions while Clang compiler runtime (compiler-rt library) is under permissive MIT license. Summary: compile with Clang when you develop the program, and with GCC for the final build (but make sure that its faster and doesn't break). Stick with Clang/LLVM if you do compiler research.
LLVM Pros. Better well known, leading to: More documentation and examples; If it's your thing, more recognisability; More bindings for various languages
May 27, 2021 · GCC uses ld as the linker with support for ld-gold. Clang uses lld as its linker. With some benchmarks, it is seen that lld is faster than ld and even the newer ld-gold. Build tool – Perhaps another place where Clang Vs GCC difference comes to the forefront. GCC uses autotools and Make as its build tools whereas Clang/LLVM uses CMake as its ...
