The issue is because __nv_tex_surf_handler built-in is still not implemented in clang. Here is the latest activity on the subject: https://reviews.llvm.org/D76365. Mark this bug as clang specific bug.

The original bug: https://bugs.llvm.org/show_bug.cgi?id=26400, which was finally fixed in clang only in Sept 2021 by https://reviews.llvm.org/D110089.

hipify-clang should be built against the latest trunk LLVM (currently, 14.0.0git).

The command line to test:

hipify-clang --print-stats --cuda-path="c:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.5" "c:\ProgramData\NVIDIA Corporation\CUDA Samples\v11.5/0_Simple/simpleSurfaceWrite/simpleSurfaceWrite.cu" --skip-excluded-preprocessor-conditional-blocks -I"c:\ProgramData\NVIDIA Corporation\CUDA Samples\v11.5\common\inc" -- -D_ALLOW_COMPILER_AND_STL_VERSION_MISMATCH

Output:
