[llvm-dev] Debug info for CUDA code

[treinz via llvm-dev]

Hi Alex, Eric and Valentin,



Thanks for the information. I don't mean to push this but I'm in desperate need of debugging some cuda code. I'm not familiar with the llvm internal but it sounds like there's at least line info now, right? If so, can you point me to a branch of llvm that can help tracing the bug down to certain line of code. I believe my bug is simply a write/read out of array boundary.



Thanks,
Char

Hi, yes, these patches are required to have tne basic debug info support. At least 2 more patches are required to be able to get values of the variables without additional manual data type casting in cuda-gdb. 


Best regards,
Alexey Bataev

Adding Alexey here who has been driving this effort in llvm.


There are about 5 patches waiting on my review:


   -: https://reviews.llvm.org/D54320
   -: https://reviews.llvm.org/D46189
   -: https://reviews.llvm.org/D51554
   -: https://reviews.llvm.org/D46061
   -: https://reviews.llvm.org/D45784


After which I think we're good.

AFAIK there is work under way from IBM (couple of PRs open), but yes Clang 7.0 doesn't produce the necessary information.

Hi all,
I found this http://lists.llvm.org/pipermail/llvm-dev/2017-November/118871.html when googling about compiling CUDA code using llvm. Is it still the case that one can't step into CUDA kernel code compiled by llvm in cuda-gdb? I'm using clang 7.0.


Thanks,
Char
