    Okay.<br>
    <br>
    The problem here was that tablegen declares those functions as
    static in the calling convention .inc file.<br>

    Then if you include the file you have to use the them or else you

                        Log:<br>
                        First stage of call lowering for Mips fast-isel<br>
                        <br>
                        Summary:<br>
                        This has most of what is needed for mips
                        fast-isel call lowering for O32.<br>
                        What is missing I will add on the next patch
                        because this patch is already too large.<br>
                        It should not be doing anything wrong but it
                        will punt on some cases that it is basically<br>
                        capable of doing.<br>
                        <br>
                        The mechanism is there for parameters to be
                        passed on the stack but I have not enabled it
                        because it serves as a way for now to prevent
                        some of the strange cases of O32 register
                        passing that I have not fully checked yet and
                        have some issues.<br>
                        <br>
                        The Mips O32 abi rules are very complicated as
                        far how data is passed in floating and integer
                        registers.<br>
                        <br>
                        However there is a way to think about this all
                        very simply and this implementation reflects
                        that.<br>
                        <br>
                        Basically, the ABI rules are written as if
                        everything is passed on the stack and aligned as
                        such.<br>
                        Once that is conceptually done, it is nearly
                        trivial to reassign those locations to registers
                        and<br>
                        then all the complexity disappears.<br>
                        <br>
                        So I have told tablegen that all the data is
                        passed on the stack and during the lowering I
                        fix<br>
                        this by assigning to registers as per the ABI
                        doc.<br>
                        <br>
                        This has been my approach and you can line up
                        what I did with the ABI document and see 1 to 1
                        what<br>
                        is going on.<br>
