<div>Is there any option for clang to turn on debug for

using something like -ggdb3 -O0 but this generate debug

<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>

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>

sometimes. I can't file a bug report

the bug report files here -- the

output from clang and the other

clang upon the crash. I'm using the
above-mentioned commit

</div>
<div>Thank you for
letting me know.
Can I assume the
the github
mirror is bumped
to 9.0 and
should contain
the commit you
mentioned? Just
want to make
sure I'm looking
at the right
repo.</div>

<p>Hi, debug

<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

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

<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>

about
compiling CUDA

still the case
that one can't
step into CUDA
