From the current SelectionDAG you can get a pointer to the Function object, which should have the attribute. Lowering for an ISD::RET can thus getting it from following this chain, -Chris _______________________________________________ llvm-commits mailing list llvm-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits
