Hi, I am having issues running a new backend that I created for a new architecture. I suspect these errors may have something to do with how I have the string setup in LLVMTargetMachine() below? Also - It would be great if someone could point me to a document that describes some of these error messages? For example what does t26 ..t4 mean? Thanks in advance for taking your valuable time to help

Hi, On SystemZ there are a set of "access registers" that can be copied in and out of 32-bit GPRs with special instructions. These instructions can only perform the copy using low 32-bit parts of the 64-bit GPRs. As reported and discussed at https://bugs.llvm.org/show_bug.cgi?id=44254, this is currently broken due to the fact that the default register class for 32-bit integers is
