C code is not really an issue. Most of the unwind complexity is handling the special case asm code, interrupt handlers, out of line lock contention paths, anything in entry.S. Much of the IA64 asm code has explicit unwind directives in the asm code, i386 asm would need equivalent kernel changes. - 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/
