+/* fold_single_bit_test() failed to return a tree of the type that the
+   outer expression was looking for.  Specifically, it returned a tree
+   whose type corresponded to QImode for !p->m, but the desired result
+   type was int, which corresponded to SImode.  emit_move_insn() later
+   tried to copy a reg:QI to reg:SI, causing an ICE.  */
