[PATCH] D139305: [clang][driver] Support option '-mcpu' on target AVR

[Alexander Richardson via Phabricator via cfe-commits]

arichardson added inline comments.


================
Comment at: clang/lib/Driver/ToolChains/CommonArgs.cpp:387
       return A->getValue();
+    if (const Arg *A = Args.getLastArg(options::OPT_mcpu_EQ))
+      return A->getValue();
----------------
It looks to me that -mcpu will always take precedence over -mmcu with this code even if mmcu comes later in the command line. Wouldn't it make more sense to treat them as aliases?
