<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>

Hi Char, unfortunately I cannot help 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>Hi Alexey,</div>
<div><br>
</div>
<div>Thanks for the great work! The version I checked
out works most of the time. But I do encounter crashes
sometimes. I can't file a bug report on <a href="https://bugs.llvm.org/" _src="https://bugs.llvm.org/" moz-do-not-send="true">https://bugs.llvm.org/</a> because
I don't have an account. I sent an email to <a href="mailto:bugs-admin@lists.llvm.org" _src="mailto:bugs-admin@lists.llvm.org" moz-do-not-send="true">bugs-admin@lists.llvm.org</a> for
an account already but I haven't heard back.
Meanwhile, can you take a look at the issue? I'm
attaching the bug report files here -- the
clang_error.log has the verbose output from clang and
the other files are generated automatically by clang
upon the crash. I'm using the above-mentioned commit
48aefa8877713616802d9c90b63f86fe50b9a101 from github
mirror. The bug is reproducible on my machine with a
nvidia RTX2080 card (sm=Turing75).</div>

<div>Are you planning
to release this as
soon as it's ready
or you want to make
it into a major
release? Is it
possible to let me
know (maybe by
replying to this
thread) once the
code is ready? I
know sometimes it
takes a while to get
things in the major
release. I greatly
appreciate your work
on this!</div>

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

<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>Hi all,</div>

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>
