dpcpp -fsanitize=memory/address

flawkjoe — Tue, 10 May 2022 13:32:11 GMT

I am trying to look for loose memory allocations in my program using the built in memory sanitizers. Unfortunately the dpcpp compiler does not accept any variation of '-fsanitize=xyz' and reports it as an unknown argument. Does anyone know how to directly set these for the clang compilation units (not the sycl kernels)?

Thank you!

Joe

I am just sharing an article this might help you.

I appreciate the reply, however the core of my issue is the inability to pass -fsanitize=xyz into the dpcpp command line. I can easily use clang or gcc and these arguments work fine, but dpcpp does not handle or forward them to the clang compiler as it should.

I also found that valgrind fails due to unknown instructions being added by the sycl compiler, presumably. I tried compiling/using the latest valgrind from git and the error persists.

I am looking into utilizing https://www.intel.com/content/www/us/en/develop/documentation/oneapi-dpcpp-cpp-compiler-dev-guide-and-reference/top/compiler-reference/compiler-options/compiler-option-details/offload-openmp-and-parallel-processing-options/fsycl-host-compiler-options.html but the problem is that it does not keep my C++ arguments. I will have to play around with CMake to see if I can get a reasonably good working solution for this.

Is there an update on this? Is there any way to do memory access and address sanitization in the sycl kernels as well?

The fix will be available in the next oneAPI release.
