+      Ctx.reportError(Fixup.getLoc(), "fixup value too large for data type!");
+    LLVM_FALLTHROUGH;
----------------
It appears like this error unfortunately can also be triggered by valid LLVM IR. @t.p.northover put up a patch to remove the error D88085. I am not sure if there is a more targeted way to only detect transforms in the backend that result in invalid overflows.
