   .ref _c_int00



*------------------------------------------------------------------------------

* This is a macro that instantiates one entry in the interrupt service table.

*------------------------------------------------------------------------------

VEC_ENTRY .macro addr

    STW   B0,*--B15

    MVKL  addr,B0

    MVKH  addr,B0

    B     B0

    LDW   *B15++,B0

    NOP   2

    NOP   

    NOP   

   .endm





*------------------------------------------------------------------------------

* This is a dummy interrupt service routine used to initialize the IST.

*------------------------------------------------------------------------------

_vec_dummy:

  B    B3

  NOP  5



*------------------------------------------------------------------------------

* This is the actual interrupt service table (IST). It is properly aligned and

* is located in the subsection .text:vecs. This means if you don't explicitly

* specify this section in your linker command file, it will default and link

* into the .text section. Remember to set the ISTP register to point to this

* table.
