Comment at: lib/FuzzMutate/FuzzerCLI.cpp:80-84
+  for (StringRef Opt : Opts) {
+    if (Opt.startswith("instcombine")) {
+      Args.push_back("-passes=instcombine");
+    } else if (Triple(Opt).getArch()) {
+      Args.push_back("-mtriple=" + Opt.str());
----------------
Why not assume everything that isn't an arch is a pass name and pass them all as a comma separated list to -passes=?
