dpcpp -fsanitize=memory/address

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!

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?
