I think the zero vector implementation should be safe. Checked in at r232061.
While we're here, do you see a problem with casting the 32-bit / packed single case to use 64-bit values instead? If we do it that way, the masks would be identical for all cases. And then we could just define the 2nd and 3rd macros in terms of the 1st? http://reviews.llvm.org/D8275 EMAIL PREFERENCES http://reviews.llvm.org/settings/panel/emailpreferences/ _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
