[PATCH] D149444: [ARM] Allow codegen for Armv6m eXecute-Only (XO) sections

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added inline comments.


================
Comment at: llvm/lib/Target/ARM/ARMSubtarget.cpp:195
+    if (!hasV6MOps())
+      llvm_unreachable("Cannot generate execute-only code for this target");
   }
----------------
If this code path is actually reachable, a proper error reporting will be better. At the least `report_fatal_error` can be used. Don't use `llvm_unreachable` for known-reachable code paths.
