Patch - GCC Port for Infineon xc16x

[Shrirang Khishti]

Hi all,

      KPIT Cummins is contributing the complete GCC port for Infineon
XC16X 
    architecture. We would like to request you to send in your comments 
    on this port.

	As we are putting our best efforts on this port its quality will

    successively improve and fit more and more to the current GNU
standards.
    KPIT Cummins has already signed copyright assignment with FSF.

      The XC16X is a new derivative of the popular C16X microcontroller

    family that is based on the enhanced C166S V2 architecture
    (http://www.infineon.com) it outperforms existing 16-bit solutions.
    Impressive DSP performance and advanced interrupt handling combined
with                 
    an integrated powerful peripheral set and a high performance on-chip

    flash makes the XC16X the instrument of choice for demanding
industrial
    and automotive applications.

	We have already submitted binutils port to FSF and it has got
accepted
   http://sourceware.org/ml/binutils/2006-02/msg00230.html. Along with
this   
   patch you need to apply following patch 
   http://sourceware.org/ml/binutils/2006-03/msg00042.html to binutils

   source so as to build the gcc.

	  	
Here is the change log for GCC patch.
