Newlib Port : Infineon xc16x

[Shrirang Khishti]

Hi all,

  KPIT Cummins is contributing the complete Newlib 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. We will be giving full fledge implementation 
of system calls as soon as possible.
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 posted binutils and gcc patches to FSF.

 Change log for Newlib 1.14
 
 We are also sending Patch for top-level config to config project
