similar to: [LLVMdev] PTX target for LLVM?

Hi, (Disabling lurk mode) I must admit, I believe this would be an extremely valuable addition to llvm, to the point where I was also seriously considering writing this backend. The main thing holding me back is the thought that other people are almost certainly working on the same thing (probably including nvidia)! I assume it's not yet ready to publish, but it's worth

Hi I am interested to know: are there are any LLVM targets in the works for Nvidia's PTX ISA? Also if anyone knows about Ocelot (a project done by some students at my school): it does the opposite of what I am trying to do (translates PTX to LLVM IR to run Cuda kernels on the CPU). Thanks in advance. -Puyan

Hi, The PTX backend we developed (CBackend approach, does not use the target independent code generator) is already more advanced. An older version is published here: http://sourceforge.net/projects/llvmptxbackend/ We recently eliminated a bug which increased the number of required registers per thread. Surprisingly, without that bug the generated code is already comparable to code generated

Hi, finally we changed the license of the PTX-backend from GPL to BSD(license of llvm). You can get the latest version here: https://sourceforge.net/projects/llvmptxbackend/ It should be compatible to the current llvm svn trunk. (revision 110329, Thu 05 Aug 2010) The backend now uses the address space attribute of LLVM for local, global, ... and constant address space. However the clang frontend

Hello Bergström/Eric, Thanks for the reply. The G80(sm_10) architecture was ported on FPGA by a group of researchers (http://www.ecs.umass.edu/ece/tessier/andryc-fpt13.pdf). Our group have some further research interest on this work. I was working on modifying the Clang-LLVM for a couple of months and achieved the required changes. But Clang-LLVM is only allowing me to generate PTX for sm_20,

Hello, Yes? Where is allActive defined, I couldn't find it. Basically, a BB is control divergent if it's execution depends on a branch that itself depends on a divergent ssa value.

Hi everyone, I downloaded the latest version of LLVM PTX backend from http://www.prog.uni-saarland.de/projects/anysl and made the required changes to all the files mentioned in the README. But I get the following error when I compile it. llvm[3]: Compiling PTXBackend.cpp for Release build In file included from PTXBackend.h:70:0, from PTXBackend.cpp:36: PTXPasses.h: In constructor

Hey everybody, good news for everyone interested in the PTX backend: We decided to release the current source code under the GPL - you can find the latest tarball here: http://www.prog.uni-saarland.de/projects/anysl You will find the README in the attachment, which should hopefully answer a lot of questions concerning the implementation and the current status. If you have further questions,

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?

Hello, It seems to me that our current DivergenceAnalysis does not save which BasicBlocks may suffer from divergent control. Am I correct? I want to modify our DivergenceAnalysis to add a "bool isControlDivergent(BasicBlock*) const" method and save in the divergence propagator the basicblock that are divergent. I am not sure that is entirely correct, if you have input on that please

Please create a similar branch for Klee; I've been working on porting that to 2.7 as well.<br /> <br /> Best, Erich Ocean<br /> <br /> On Fri, Mar 5, 2010 at 8:43 PM, John Criswell (criswell@uiuc.edu) wrote:<br /> > <br /> > Dear SAFECoders and LLVMers,<br /> > <br /> > There is some new work on moving DSA to the new LLVM 2.7 API.
