If "addr" is properly aligned for an "int", but misaligned for a long ... i.e. addr%8 == 4, then I'll take an unaligned reference trap if I work with long* where the current code working with int* does not. Now perhaps all the callers do guarantee long* alignment? But I don't know. Apart from uniformity, there doesn't see to be any upside to changing this. -Tony Luck -- To unsubscribe from this list: send the line "unsubscribe linux-alpha" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
