[PATCH] D99551: [clang-offload-wrapper] Add standard notes for ELF offload images

[Joseph Huber via Phabricator via cfe-commits]

jhuber6 added a comment.

This patch broke offloading on my machine. If I compile a basic offloading application I get an invalid device image.

  #include <omp.h>
  
  int main() {
    int isHost;
  #pragma omp target map(from:isHost)
    { isHost = omp_is_initial_device(); }
    return isHost;
  }

Compiling and running with `clang -fopenmp -fopenmp-targets=nvptx64` gives me the following results.

  CUDA error: Error returned from cuModuleLoadDataEx
  CUDA error: device kernel image is invalid 
  Libomptarget error: Unable to generate entries table for device id 0.
  Libomptarget error: Failed to init globals on device 0
  Libomptarget error: Run with LIBOMPTARGET_INFO=4 to dump host-target pointer mappings.
  Libomptarget fatal error 1: failure of target construct while offloading is mandatory

Reverting `93d08acaacec951dbb302f77eeae51974985b6b2` fixes it.
