Re: PATCH to build1 for c/12553


    +                 int i = first_rtl_op (TREE_CODE (node));
    +                 for (; i >= 0; --i)

    Isn't there a problem if "node" has only tree operands here, because
    "i" starts as the number of operands in that case ?

Actually, there's a problem in *all* cases: this is an off-by-one error.
It should be first_rtl_op (...) - 1.  Making that change is pre-approved.
