GCC, Clang and MSVC are powerful compilers, with many heuristics to emit the most efficient instructions, maybe even optimal ones. The same goes for ICC, a.k.a Intel’s compiler, well known for outranking all the others regarding the performance of the generated code. We rarely talk about it but it is here. (By the way, did you know that Intel is migrating his compiler to LLVM? The new compiler’s name is ICX for the C language, and ICPX for C++).
