================
Comment at: llvm/unittests/Object/ELFObjectFileTest.cpp:77-83
+TEST(ELFObjectFileTest, MachineTestForNone) {
+  checkFormatAndArch({ELF::ELFCLASS64, ELF::ELFDATA2LSB, ELF::EM_NONE},
+                     "elf64-unknown", Triple::UnknownArch);
+
+  checkFormatAndArch({ELF::ELFCLASS32, ELF::ELFDATA2LSB, ELF::EM_NONE},
+                     "elf32-unknown", Triple::UnknownArch);
+}

Reasonable, I think. Done.

Done.
