optimization/9123: [3.2/3.3/3.4 regression ] Internal compiler error in do_SUBST at combine.c:434

[Janis Johnson]

The regression appeared with this patch:

2001-04-12  Alexandre Oliva  <aoliva@redhat.com>

        * recog.c (general_operand, immediate_operand,
        nonmemory_operand): Require CONST_INTs to be sign-extended
        values for their modes.

The search used the smaller C++ test case.
