This revision now requires changes to proceed.

Does the name of the `-falways-need-cfi` option match any existing compiler (google doesn't find anything)? If not, I think it would make more sense as a `-g` option, as it's similar to `-gline-tables-only`.



================
Comment at: clang/lib/Frontend/CompilerInvocation.cpp:956
                                          OPT_fno_unique_section_names, true);
+  Opts.AlwaysNeedCFI =
+      Args.hasFlag(OPT_falways_need_cfi, OPT_fno_always_need_cfi, false);
----------------
Is this option actually being read anywhere?
