--- Comment #1 from Roland Illig <roland.illig at gmx dot de> --- Just another remark: The words "BIT_FIELD_REF of non-mode-precision operand" do not occur anywhere in the test suite. They should. Or did I miss something? If this is meant to be unreachable code, it should rather be an "assert" instead of an "error".
