Better how? There are plenty of benchmarks showing that gcc's optimizations are more performant than llvm's.

And here are plenty that support the converse ;) I don't think there's anything that points to one being definitively better than the other in performance.

Clang has this too.

Not as much as GCC.

That’s a bug, not an optimization.

Every performant compiler on the SPECcpu benchmarks does this.
