similar to: [LLVMdev] TableGen patterns with multiple outputs

Thanks for the info. Is this on someone's list of things to do?

It is a known limitation. You have to write C++ code to match patterns with multiple outputs. > > If I have TableGen code like the following... > > 1242 def SDTTestNode

It has been something we've talked about for years, but I'm not aware of anyone working on it right now.

Hi Jacob, thank you for your reply. Your suggestion works! But instead of using the Pat<>, I am using def MOVE_ADDR : MYInst<(outs Int32Regs:$dst), (ins i32mem:$a), "move $dst, $a;", [(set Int32Regs:$dst, (Wrapper tglobaladdr:$a))]>; I don't quite understand what the semantics of Pat in general. Could you please explain what

Hello, I am learning to write a new backend for LLVM and have a few simple questions. 1) What are the differences between 'constant' and 'targetconstant', 'globaladdress' and 'targetglobaladdress'? It is not clear from the document when and which should be used. 2) On the processor I am working on, there is a 'move reg, mem_addr' instruction. When I try

For those of you who haven't noticed, I'm planning to commit a major change to the Makefile rules tomorrow evening (Tuesday) if there are no complaints about it between now and then. This needs testing on Darwin. I've heard back from Linux on many platforms and even FreeBSD, which is fantastic, but I'm told that lots of LLVMers are running Darwin and I haven't heard a peep

This also broke the build for MSVC when doing a debug build (though no builder seems to be picking up the failure!). After

You are welcome. I changed the pattern, the same old error pop up again, crash in the same place.

Hello LLVM developers, Following some hints on this mailing list earlier this year on how to make clang faster than stock llvm.org builds I have implemented a script that builds a PGO optimized version of clang by following the guide here: http://llvm.org/docs/HowToBuildWithPGO.html This works great on macOS and Linux - we gained almost 15% in our project with this technique. I am now looking at

Hi Justin, I download llvm-ptx-samples [1] and try to build them. I found it seems lack of a complete document on how to build them with LLVM/Clang/libclc. Do you think it's a good idea to put a complete document/tutorial in _one_ place? Currently, there are your website [2], LLVM [3], Clang and libclc websites [5] over there. I feel people might get lost among those websites. ;-) Here
