<div>Hi Char, sorry, you need to wait a little bit. It is almost
ready, but not yet. For now, use nvcc if you need debug info for
Cuda.<br>

<div>Hi Alex, Eric and Valentin, <br>
</div>
<div><br>
</div>
<div>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.<br>

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. <br>

<div>I found this <a href="http://lists.llvm.org/pipermail/llvm-dev/2017-November/118871.html" rel="noreferrer noreferrer" target="_blank">
http://lists.llvm.org/pipermail/llvm-dev/2017-November/118871.html</a>
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.</div>
