Hi, I work in a large CUDA codebase and use Clang to build some of our CUDA code to improve compilation speed. We're planning to upgrade to CUDA 11 soon, and it appears that CUDA 11 is not yet supported in LLVM. >From the LLVM commits history, I can see that work on CUDA 11 has started. Is this currently being worked on? What is the remaining work left? And is any help needed to finish

Hello, When generating the PTX output from CUDA file(.cu file), the minimum target that is accepted by LLVM is sm_20. But I have a specific requirement to generate PTX output for compute capability 1.0 (sm_10). Is there any previous version of LLVM supporting this? Thank you, Ginu -------------- next part -------------- An HTML attachment was scrubbed... URL:

Clang currently doesn't support CUDA separate compilation and thus extern __device__ functions and variables cannot be used. Could someone give me any pointers where to look or what has to be done to support this? If at all possible, I'd like to see what's missing and possibly try to tackle it. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I was wondering if anyone has encountered this issue when cross compiling cuda on Nvidia TX2 running android. The error is In file included from <built-in>:1: In file included from prebuilts/clang/host/linux-x86/clang-4667116/lib64/clang/7.0.1/include/__clang_cuda_runtime_wrapper.h:219: ../cuda/targets/aarch64-linux-androideabi/include/math_functions.hpp:3477:19: error: no matching function

David's change makes nvvm_reflect_anchor unnecessary. The issue with dots in names generated by llvm still needs to be fixed.

Hello everyone, Below are some buildbot numbers for the last week of 6/05/2016 - 6/11/2016. Thanks Galina buildername | was_red -----------------------------------------------------------+----------- sanitizer-x86_64-linux-bootstrap | 134:12:25 perf-x86_64-penryn-O3-polly-parallel-fast | 46:29:26

Yeah, '.' is the direct reason for the ptxas failure here. I'm curious, however, about what the purpose of nvvm_reflect_anchorv() is here, and why does the front-end always generate this function? Since the current PTX emission doesn't mangle dots, it would be a reasonable workaround for me to prevent the front-end from generating this function in the first place. Is there any

OK, I see the problem. You were right that we weren't picking up libdevice. CUDA 7.0 only ships with the following libdevice binaries (found /path/to/cuda/nvvm/libdevice): libdevice.compute_20.10.bc libdevice.compute_30.10.bc libdevice.compute_35.10.bc If you ask for sm_50 with cuda 7.0, clang can't find a matching libdevice binary, and it will apparently silently give up and try to

Hi llvm-admin, (cc llvm-dev for visibility) We’re working on some improvements to the documentation, and want to move things (e.g. the Kaleidoscope tutorial into a subdirectory) around without breaking any links to it. Is there a way to do forwards on the web page that you prefer? -Chris

Thanks Quentin. I'm trying to examine from the operands of the return instruction, and then to get the last assignment of those. I thought use_iterator/reg_iterator may suit better than just loop through the machine basicblock in the reverse order.

Hi Alexey, Almost a year has passed and Nvidia finally fixes the ptxas issue in CUDA 10.2 according to: https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#cuda-compiler-resolved-issues However, I can not yet use it with llvm 9.0.0 release because CUDA 10.2 is not supported yet. Is there other branches of the llvm repo that supports CUDA 10.2 now? Or do I need to wait for llvm 10

Hi all, I'm trying to write a custom module-level pass that runs before AsmPrinter::EmitStartOfAsmFile(), since I'd like to have some processed information available once entering this function. Looking through "Writing an LLVM pass" documentation, it's not clear to me if this is possible. I've also tried putting the pass in different orders (addPreISel, addIRPasses,

Hi folks, I would like to find out the machine instructions that use some given registers in the reverse order, and I came across these iterators (use_iterator/reg_iterator). However, there are two things I noticed: 1) These iterators seem to traverse the machine function a bit differently from what I get from the machine function dump. In other words, the use_iterator list is not constructed in

Dear all, Attached notunrolled.ll is a module containing reduction kernel. What I'm trying to do is to unroll it in such way, that partial reduction on unrolled iterations would be performed on register, and then stored to memory only once. Currently llvm's unroller together with all standard optimizations produce code, which stores value to memory after every unrolled iteration, which is

Hi guys, I’m trying to figure out a way to assign initial values to function arguments. For a function in IR: define i32 @main (i32 %0, i32 %1) { %tmp = add i32 %0, %1 ... } I would like to make sure %0 has some initial value (e.g. i32 0) under some circumstances. Is there any easy way to do this? I understand that %0 comes from a live-in value which is defined from outside of the function. I
