;; A bitcode file can generate undefined references to symbols that weren't
;; listed as undefined on the bitcode file itself, when lowering produces
;; calls to e.g. builtin helper functions. If these functions are provided
;; as LTO bitcode, the linker would hit an unhandled state. (In practice,
;; compiler-rt builtins are always compiled with -fno-lto, so this shouldn't
;; happen.)
