The problem is that the threshold for that is architecture specific. While e.g. x86 has relatively low overhead of prologue/epilogue other architectures like s390 have enormous overhead. So handling this in the compiler would be optimal, but it would need at least whole-program optimization and a compiler aware of the inline assembly to get it half-way right. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
