Summary:  addsi_a0_seg_base is too slow

Original Submission:  The current implementation of addsi_a0_seg_base results

in the following code:



    mov    $0x0,%eax

        R_386_32  __op_param1

    lea    0x0(,%eax,4),%eax

        R_386_32  __op_param1

    add    0x58(%ebp,%eax,4),%edi



Which is _too_ much.  This could probably be replaced with

just one insn (the add) if you give the address to the

base directly as a parameter to the micro-op.
