Thanks Honza. Just one comment: > The runtime benefits are more visible on bigger, bloated and less > optimized projects than on hand tuned video encoder implementation. > I believe Kernel largely falls into hand tuned category despite its size.
In my experience there's a lot of badly tuned code in the kernel these days, especially when you go outside the core code (i.e. into drivers/*) Or code that used to be tuned, but isn't aftermore after several years of feature additions and bug fixes. The kernel code quality is also quite varying. So anything the compiler can do helps. > I would be curious about the results on Kernel. We saw some upsides in performance with some standard tests, but nothing too significant. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
