Yes, the x86-64 64bit vsyscalls predate all the vDSO work and haven't been updated. It has a vDSO for 32bit programs though. I guess it would be not that much work to add it for 64bit too. I would not be opposed to it if somebody sends me patches. This means my only objection is that an dwarf2 unwind table written without the .cfi_* support in the assembler is incredibly ugly and unmaintainable. I really don't want to have more such ugly tables. I guess it would be best to force an binutils update for dwarf2 information. -Andi - 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/
