Benchmarks "Google has released a research paper that suggests C++ is the best-performing programming language in the market. The internet giant implemented a compact algorithm in four languages - C++, Java, Scala and its own programming language Go - and then benchmarked results to find 'factors of difference'."

RE[5]: GCC isn't all that great

I couldn't tell you more about GCC vectorisation in any great detail.

I have seen restrict et al work (that is generate vector code) on ARM for the NEON instruction set but right now I can't remember if that was RVCT or GCC. If ARM is your thing it might be worth checking the builds of GCC. For x86 - I'm afraid I've no idea. I just hit "build" in Qt Creator as none of my x86 code is really that performance critical anymore!

There seem to have been a small army of devs reporting issues with 'restrict' since 2002, which have been marked as dups of each other. They ultimately point to this bug which indicates a fix in GCC 4.5.
