Seeking Guidence on Porting GCC

Seeking Guidence on Porting GCC

[Sriharsha Vedurmudi]

Hi,

   I am from a company where we have developed a new DSP-type Processor 
and plan to port an RTOS onto it for use with some wireless Stuff. For 
this, we wanted to port the GCC toolchain for our processor. We have 
outsourced it to another company and now, I am made incharge of it from 
the time it is delivered to us (means, I'd be responsible to fix any 
bugs that arise at later date and provide customer support for the same).
    Problem: I have never worked at Sub-Compiler level. Im very 
comfortable with C and some popular command line options of gcc and ld. 
Nothing much more than that (plus ofcourse using some utilities like nm 
etc etc). I would like some guidence from a good samaritan on the 
aspects of Porting GCC toolchain (What part of the entire code needs to 
be changed? What are the pitfalls to watch for when I receive the ported 
version? etc...).

    What I have Done: I have been Bugging Mr. Google for information 
regarding this, but somehow the results were not satisfactory. Then I 
tried looking at the source code and decided against it when my deadline 
arrived.

    Now, Im really stuck and desperately need help.

Thank you in advance for any help you extend. (I'd greatly appreciate if 
you can atleast provide me with some links that might be useful or serve 
as a guide).

Warm Regards,
Sriharsha.
