Hi LLVM-Folks, as mentioned in an earlier post (http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-July/051677.html) I am currently working on a Back-End for the TriCore processor. Currently, I am struggling as LLVM could not select zext and load, for instance, so some of the testcases in test/CodeGen/Generic are not successfully compiled by my back-end. Furthermore, I am completely puzzled by the

...tructions. Since they aren't selected at ISel time, they have no pattern. > > > [Villmow, Micah] Have you tried using a tablegen pattern here?
