<p>Hi Char, not sure if clang supports 10.2. You can ry to use trunk
instead of release and check it yourself. Most probably clang 10
will support cuda 10. Also, you can use cuda 9 safely, just
replace ptxas in the installation dir with the newest ptxas from
cuda 10.2<br>

<div style="position:relative;zoom:1">Almost a year has passed
and Nvidia finally fixes the ptxas issue in CUDA 10.2
according to: <a

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 releaase.</div>

<p>Hi Char, yes, this line causes the crash. You don't
need .cu files (I don't know what files are you
talking about, clang does not generate .cu files). You
need just this .s file to reproduce the error and
nothing else.<br>

you with these crashes, because they caused not by
clang /LLVM, but the NVidia's PTX-to-SASS
translator ptxas. It is ptxas who crashes and I
can't do anything about this. You need to report
the bug to NVidia, but you need to manually run
the ptxas tool with the generated .s file.
Sometimes it helps to compile the code
sequentially, not using the parallel builds. Plus,
those crashes may disappear from time to time.<br>

<div>Thank you for

<p>Hi, debug info for
the NVPTX is

planning to

it's ready or
you want to

Is it possible

once the code

it takes a

sorry, you
need to wait a

yet. For now,

<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
