Title: a bug report of gas (binutils-2.11)

Hello. My name is H.Saito from Japan.

I report a bug of gas (binutils-2.11), when specified '-mips3' option.

xxx.s is a assembler test program.
This assembler program is a part of C program.

fff(){}
int (*ppp)();
main()
{
        ppp = fff;
        (*ppp)();
}

---start xxx.s:---------------------
        .abicalls

        lw      $16,ppp
        move    $25,$16
        jal     $31,$25

        .comm   ppp,4
---end xxx.s:---------------------

Gas-2.11 generates illegal code.
   0:   df900000        ld      $s0,0($gp)
But I hope to generate this code.
   0:   8f900000        lw      $s0,0($gp)

Thank you. Good bye.
