My general experience with compiler generated prefetches right now is pretty poor for kernel type code. Its hard to do it right in the compiler for complex stuff rather than 'fortran in C' type jobs We certainly could perl the asm to drop in the right directives if it became an issue, but there are children on the list so lets worry about it if it becomes a problem - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
