This revision now requires changes to proceed.

Aliasing `-march=help` to `--print-supported-extensions` looks weird. I think this patch should remove `-march=help`.



================
Comment at: clang/test/Driver/print-supported-marchs.c:1
+// Test that --print-supported-extensions lists supported extensions.
+
----------------
The filename should be fixed.
