[Craig Topper via Phabricator via cfe-commits]

craig.topper added inline comments.


================
Comment at: clang/lib/Driver/ToolChains/CommonArgs.cpp:1723
+  if (Args.hasArg(options::OPT_fuse_unaligned_vector_move))
+    addArg(Twine("-x86-enable-unaligned-vector-move=true"));
+  else if (Args.hasArg(options::OPT_fno_use_unaligned_vector_move))
----------------
Could you just put this in target features in the IR and not have to deal with LTO specially? Similar to what we do with retpoline, speculative loading hardening, etc.
