GNU as only does DV checking if the -x option is specified. The DV checking stuff was never properly finished. It should be enabled by default. And we should emit errors instead of warnings for provable DVs. However, if we did that, we would then have the problem that false positives from bugs would prevent the compiler from working. So we would have to add an option to disable DV checking and have the compiler emit it. But then we would have the problem that the compiler output would not get any DV checking from the assembler, which is a worse problem than what we have now. We really need to get the bugs fixed first, and then emit errors by default for DVs. I'm glad to see that HJ has time to work on these problems. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Mon Oct 20 18:26:44 2003
