My code consists of tight loops used for numerical simulation. Clang runs about 2x slower. Hence I conclude that Clang is bad for optimizing tight loops.
Many of the Clang vs. GCC tests are clandestinely skewed towards llvm because they involve code that does not benefit from low level optimization.
Many of the people who work on GCC are scientists who want tight loop performance while many of the folks who work on clang want a BSD license.
