[Alexey Bataev via Phabricator via cfe-commits]

ABataev added inline comments.


================
Comment at: include/clang/Basic/DiagnosticDriverKinds.td:207-208
+def remark_drv_omp_offload_target_missingbcruntime : Warning<
+  "Expect degraded performance on the target device due to missing '%0' in LIBRARY_PATH.">,
+  InGroup<OpenMPTarget>;
 def err_drv_bitcode_unsupported_on_toolchain : Error<
----------------
Fix the message in the warning, it does not follow the logic of the patch


================
Comment at: lib/Driver/ToolChains/Cuda.cpp:586
+  if (DeviceOffloadingKind == Action::OFK_OpenMP) {
+    SmallVector<std::string, 8> LibraryPaths;
+    // Add path to lib and/or lib64 folders.
----------------
Do you really need `std::string` here? Or StringRef is enough?
