However, that patch resulted in an ICE in some other cases, and unnecessary saves/restores of ar.pfs, see gcc PR 10681. The patch for that is in gcc-3.3.1. See Richard Henderson's 2003-06-26 change in gcc. It would be reasonable to just check for >= gcc-3.3 for use of this feature. I wouldn't recommend using gcc-3.3.0 though. -- 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 Thu Nov 27 17:43:45 2003
