================
Comment at: clang/lib/Driver/ToolChain.cpp:753
             : tools::arm::getARMTargetCPU(MCPU, MArch, Triple);
     StringRef Suffix =
       tools::arm::getLLVMArchSuffixForARM(CPU, MArch, Triple);
----------------
Suffix originally set here, from any compiler options.


================
Comment at: clang/lib/Driver/ToolChain.cpp:807
+        // over -Wa,-march. Which matches the compiler behaviour.
+        Suffix = tools::arm::getLLVMArchSuffixForARM(WaMCPU, WaMArch, Triple);
+      }
----------------
Then we override that if we're using the assembler and have -Wa options.
