Comment at: clang/lib/Driver/ToolChains/Clang.cpp:4442-4446
+ std::string CPU = getCPUName(Args, Triple, /*FromAs*/ false);
+ if (!CPU.empty()) {
+ CmdArgs.push_back("-target-cpu");
+ CmdArgs.push_back(Args.MakeArgString(CPU));
+ }

Fair. I'll update it.
================
Comment at: clang/test/Driver/embed-bitcode-nvptx.cu:1
+// RUN: %clang -Xclang -triple -Xclang nvptx64 -S -Xclang -target-feature
-Xclang +ptx70 -fembed-bitcode=all --cuda-device-only -nocudalib -nocudainc %s
-o - | FileCheck %s
+// REQUIRES: nvptx-registered-target

I'll go with your options.
