What about long long? I think there is support, at least at the IR level. Anyway, ARM does support long long, so if there isn't yet, we should add. > For additional builtins that map directly to ldrex/strex, which I'm given to > understand ARM's compiler supports, we would indeed need new intrinsics (one > for each data size).

Yup, they can be a Custom lowering in ARMISelLowering... cheers, --renato _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
