[LLVMdev] Instructions working on 64bit registers without true support for 64bit operations
Fabian, We have a very similar setup with the AMDIL backend(some operations support 64bit some don't). What we do is we enable MVT::i64, set legal to all operands that are legal and then set everything else to expand.

Unfortunately, I didn't find any time to work on my problem in the meantime as I was busy preparing lectures. However, the summer

[LLVMdev] Instructions working on 64bit registers without true support for 64bit operations
Hello Tom, > I took a look at lib/CodeGen/SelectionDAG/LegalizeDAG.cpp and it > doesn't look like there is an Expand operation implemented for > ISD::Constant. I think you'll either need implement Expand for > ISD::Constant or Custom lower it in your backend. thank you for that information. This exactly is what I feared. Well I did some more mostly unguided hacking and these

[LLVMdev] More Back-End Porting Troubles
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

[LLVMdev] Pointer argument type in SparcISelLowering.cpp
Hi Raghu, > I am working with the "LowerCall" function, and trying to figure out the types of all the "Outs" arguments. Specifically, I want to find out if a particular "Out[i]" argument is a pointer (of any type), or a regular data type. So far, all pointers show up as the "MVT::i32" datatype, which is not helping my cause. Is there a way to distinguish
