...ave a crash in NVPTX backend: LLVM ERROR: Cannot select: 0x732b270: i64 = ExternalSymbol'__powisf2' [ID=18] As I understand LLVM tries to lower the following call %28 = call ptx_device float @llvm.powi.f32(float 2.000000e+00, i32 %8) nounwind readonly to device intrinsic. The table llvm/IntrinsicsNVVM.td does not contain such intrinsic, however it should be builtin, according to cuda/include/math_functions.h Is my understanding correct, and we need simply add the corresponding definition to llvm/IntrinsicsNVVM.td ? How to do that, what are the rules? Thanks, - D.

Justins: I noticed that the intrinsics in IntrinsicsNVVM don't specify a TargetPrefix. This seems like a simple omission, so I was going to simply throw a `let TargetPrefix = "nvvm" ` block around them, but this doesn't quite work. There seem to be three prefixes that are used in this file. About 900 are int_nvvm_*, 30 are int_ptx_*, a...

Hi: Does Clang support CUDA? I am looking for a front end for my compiler that can take CUDA programming framework.

The identifier INT_PTX_SREG_TID_X is the name of an instruction as the back-end sees it, and has very little to do with the name you should use in your IR. Your best bet is to look at the include/llvm/IR/IntrinsicsNVVM.td file and see the definitions for each intrinsic. Then, the name mapping is just: int_foo_bar -> llvm.foo.bar() int_ prefix becomes llvm., and all underscores turn into periods. Ex: int_nvvm_read_ptx_sreg_tid_x -> llvm.nvvm.read.ptx.sreg.tid.x() On Fri, Mar 1, 2013 at 3:51 PM, Pete...

Hi, I am sorry for sending this query again here, but maybe I sent it to wrong list yesterday. I am trying to compile LonestarGPU-rev2.0 <http://iss.ices.utexas.edu/?p=projects/galois/lonestargpu/download> benchmark suite with LLVM/CLANG. This suite has a following piece of code (more info here

Hi LLVMers, We at NVIDIA would like to contribute back to the LLVM open-source community by up-streaming the NVPTX back-end for LLVM. This back-end is based on the sources used by NVIDIA, and currently provides significantly more functionality than the current PTX back-end. Some functionality is currently disabled due to dependencies on LLVM core changes that we are also in the process of

Hi Timothy, I'm not sure what you mean by this working for other intrinsics, but in this case, I think you want the intrinsic name llvm.nvvm.read.ptx.sreg.tid.x. For me, this looks like: %x = call i32 @llvm.nvvm.read.ptx.sreg.tid.x() Pete On Fri, Mar 1, 2013 at 11:51 AM, Timothy Baldridge <tbaldridge at gmail.com> wrote: > I'm building this with llvm-c, and accessing these

I'm building this with llvm-c, and accessing these intrinsics via calling the intrinsic as if it were a function. class F_SREG<string OpStr, NVPTXRegClass regclassOut, Intrinsic IntOp> : NVPTXInst<(outs regclassOut:$dst), (ins), OpStr, [(set regclassOut:$dst, (IntOp))]>; def INT_PTX_SREG_TID_X : F_SREG<"mov.u32 \t$dst, %tid.x;",
