dpct giving SIGSEGV during conversion

Hi,

I was converting dump_reg_shmem.cu from repo cutlass and dpct gave SIGSEGV

Output:

C:\Users\intel\Downloads\cuda code\dpct_repos\cutlass\examples\02_dump_reg_shmem>dpct --cuda-include-path="C:\nvcc\include" --extra-arg="-I../../tools/util/include" --extra-arg="-I../common" --extra-arg="-I../../include" --out-root=dpct dump_reg_shmem.cu
NOTE: Could not auto-detect compilation database for file 'dump_reg_shmem.cu' in 'C:\Users\intel\Downloads\cuda code\dpct_repos\cutlass\examples\02_dump_reg_shmem' or any parent directory.
Processing: C:\Users\intel\Downloads\cuda code\dpct_repos\cutlass\examples\02_dump_reg_shmem\dump_reg_shmem.cu

Hi Gagan,

We are also getting the same error while migrating the file(dump_reg_shmem.cu) mentioned by you. So we are escalating it to the concerned team.

 

Warm Regards,

Abhishek

I don't see a segfault with the latest DPCT. See the following behavior:


C:\Users\amadhuso\Downloads\cutlass\examples\02_dump_reg_shmem>dpct --extra-arg="-I../../tools/util/include" --extra-arg="-I../common" --extra-arg="-I../../include" --out-root=dpct dump_reg_shmem.cu
