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:$a))]>; I don't quite understand what the semantics of Pat in general. Could you please explain what def : Pat<(BfinWrapper (i32 tglobaladdr:$addr))...

...' 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 to match it using the pattern [(set Int32Regs::reg, tglobaladdr::mem_addr)]. the code generated by tblgen cannot be compiled because there will be a switch statement that contains two cases for the 'tglobaladdr', one is hard-coded in by tblgen and the other is generated by tbglen following the pattern I specified. The compilation fail...

Timothy, Those calls to compute grid intrinsics are definitely wrong. In ptx code they should end up into reading special registers, rather than function calls. Try to take some working example and figure out the LLVM IR differences between it and the result of your compiler. - D. ----- Original message ----- > I've written a compiler that outputs PTX code, the result seems fairly >

I've written a compiler that outputs PTX code, the result seems fairly reasonable, but I'm not sure the intrinsics are getting compiled correctly. In addition, when I try load the module using CUDA, I get an error: CUDA_ERROR_NO_BINARY_FOR_GPU. I'm running this on a 2012 MBP with a 640M GPU.
